Media quary not behaving like i want it

Hey there,

Due to a wrist injury i have been trying to keep myself busy the last couple of days trying to HTML and i must say it has been a interesting ride so far.

Now to get to my problem: When changing the body format via a media quary and clicking one of the links, the site still point to the right section however, the section is behind the navigation bar (navbar) for some reason. i have tryed to set the “main content” below the navbar via “position absolute” but issue persists.

Any chance someone can help me out with this?

Love to add my code but it won’t let me…

          <p>JavaScript is a cross-platform, object-oriented scripting language.
             It is a small and lightweight language. Inside a host environment
             (for example, a web browser), JavaScript can be connected to the objects
             of its environment to provide programmatic control over them.
            </p>

          <p>JavaScript contains a standard library of objects, such as Array,
              Date, and Math, and a core set of language elements such as operators,
              control structures, and statements. Core JavaScript can be extended
              for a variety of purposes by supplementing it with additional objects; for example:
          </p>

            <ul>
              <li>
                Client-side JavaScript extends the core language by supplying objects to control
                  a browser and its Document Object Model (DOM). For example, client-side extensions
                  allow an application to place elements on an HTML form and respond to user events
                  such as mouse clicks, form input, and page navigation.
              </li>
              <li>Server-side JavaScript extends the core language by supplying objects relevant to
                  running JavaScript on a server. For example, server-side extensions allow an application
                  to communicate with a database, provide continuity of information from one invocation to
                  another of the application, or perform file manipulations on a server.
                </li>
            </ul>

              <h2>JavaScript and Java</h2>
            </header>
            <p>JavaScript and Java are similar in some ways but fundamentally different in some others.
              The JavaScript language resembles Java but does not have Java's static typing and strong
              type checking. JavaScript follows most Java expression syntax, naming conventions and basic
              control-flow constructs which was the reason why it was renamed from LiveScript to JavaScript.
            </p>
            <p>In contrast to Java's compile-time system of classes built by declarations, JavaScript supports
              a runtime system based on a small number of data types representing numeric, Boolean, and string
              values. JavaScript has a prototype-based object model instead of the more common class-based object model.
              The prototype-based model provides dynamic inheritance; that is, what is inherited can vary for individual
              objects. JavaScript also supports functions without any special declarative requirements. Functions can be
              properties of objects, executing as loosely typed methods.
            </p>
            <p>JavaScript is a very free-form language compared to Java. You do not have to declare all variables, classes,
              and methods. You do not have to be concerned with whether methods are public, private, or protected, and you do
              not have to implement interfaces. Variables, parameters, and function return types are not explicitly typed.
            </p>

          <p>To get started with writing JavaScript, open the Scratchpad and write
            your first "Hello world" JavaScript code:
          </p>

          <p class="code">
            <code>
              function greetMe(yourName) { alert("Hello " + yourName); }<br />

      <section id="variables" class="main-section">
        <header>
          <h2 id="variables">Variables</h2>
        </header>
        <p>You use variables as symbolic names for values in your application. The names of variables,
          called identifiers, conform to certain rules.
        </p>
        <p>A JavaScript identifier must start with a letter, underscore (_), or dollar sign ($); subsequent
          characters can also be digits (0-9). Because JavaScript is case sensitive, letters include the characters
          "A" through "Z" (uppercase) and the characters "a" through "z" (lowercase).
        </p>
        <p>You can use ISO 8859-1 or Unicode letters such as å and ü in identifiers. You can also use the Unicode
          escape sequences as characters in identifiers. Some examples of legal names are Number_hits, temp99, and _name.
        </p>
      </section>

      <section id="declaring_variables" class="main-section">
        <header>
          <h2>Declaring variables</h2>
        </header>
        <p>You can declare a variable in three ways:</p>
        <p>With the keyword var. For example,</p>
        <p class="code"><code>var x = 42.</code></p>
        <p>This syntax can be used to declare both local and global variables.</p>
        <p>By simply assigning it a value. For example,</p>
        <p class="code"><code>x = 42.</code></p>
        <p>This always declares a global variable. It generates a strict JavaScript warning. You shouldn't use this variant.</p>
        <p>With the keyword let. For example,</p>
        <p class="code"><code>let y = 13.</code></p>
        <p>This syntax can be used to declare a block scope local variable. See Variable scope below.</p>
      </section>

      <section id="variable_scope" class="main-section">
        <header>
          <h2>Variable scope</h2>
        </header>
        <p>When you declare a variable outside of any function, it is called a global variable,
          because it is available to any other code in the current document. When you declare a
          variable within a function, it is called a local variable, because it is available only within that function.
        </p>

        <p>JavaScript before ECMAScript 2015 does not have block statement scope; rather, a variable
          declared within a block is local to the function (or global scope) that the block resides within.
          For example the following code will log 5, because the scope of x is the function (or global context)
          within which x is declared, not the block, which in this case is an if statement.
        </p>

        <p class="code"><code>if (true) { var x = 5; } console.log(x); // 5</code></p>

        <p>This behavior changes, when using the let declaration introduced in ECMAScript 2015.</p>

        <p class="code"><code>if (true) { let y = 5; } console.log(y); // ReferenceError: y is not defined</code></p>
      </section>


      <section id="global_variables" class="main-section">
        <header>
          <h2>Global variables</h2>
        </header>
        <p>Global variables are in fact properties of the global object. In web pages the global object is window, so you can set and access global variables using the window.variable syntax.
        </p>

        <p>Consequently, you can access global variables declared in one window or frame from another window or frame by specifying the window or frame name. For example, if a variable called phoneNumber is declared in a document, you can refer to this variable from an iframe as parent.phoneNumber.
        </p>
      </section>

      <section id="constants" class="main-section">
        <header>
          <h2>Constants</h2>
        </header>
        <p>You can create a read-only, named constant with the const keyword. The syntax of a constant identifier is the same as for a variable identifier: it must start with a letter, underscore or dollar sign and can contain alphabetic, numeric, or underscore characters.
        </p>

        <p class="code"><code>const PI = 3.14;</code></p>
        <p>A constant cannot change value through assignment or be re-declared while the script is running. It has to be initialized to a value.
        </p>

        <p>The scope rules for constants are the same as those for let block scope variables. If the const keyword is omitted, the identifier is assumed to represent a variable.
        </p>

        <p>You cannot declare a constant with the same name as a function or variable in the same scope. For example:
        </p>

        <p class="code">
          <code>
            // THIS WILL CAUSE AN ERROR function f() {}; const f = 5;<br />
            // THIS WILL CAUSE AN ERROR ALSO function f() { const g = 5; var g; //statements}
          </code>
        </p>

        <p>However, object attributes are not protected, so the following statement is executed without problems.
        </p>
        <p class="code"><code>const MY_OBJECT = {"key": "value"}; MY_OBJECT.key = "otherValue";</code></p>
      </section>

      <section id="data_types" class="main-section">
        <header>
          <h2>Data types</h2>
        </header>
        <p>The latest ECMAScript standard defines seven data types:
        </p>
        <ul>
          <li>Six data types that are primitives:</li>
          <ul>
            <li>Boolean. true and false.</li>
            <li>null. A special keyword denoting a null value. Because JavaScript is case-sensitive, null is not the same as Null, NULL, or any other variant.</li>
            <li>undefined. A top-level property whose value is undefined.</li>
            <li>Number. 42 or 3.14159.</li>
            <li>String. "Howdy"</li>
            <li>Symbol (new in ECMAScript 2015). A data type whose instances are unique and immutable.</li>
          </ul>
          <li>and Object</li>
        </ul>
        <p>Although these data types are a relatively small amount, they enable you to perform useful functions with your applications. Objects and functions are the other fundamental elements in the language. You can think of objects as named containers for values, and functions as procedures that your application can perform.
        </p>
      </section>

      <section id="if...else_statement" class="main-section">
        <header>
          <h2>if...else statement</h2>
        </header>
        <p>Use the if statement to execute a statement if a logical condition is true. Use the
          optional else clause to execute a statement if the condition is false. An if statement
          looks as follows:
        </p>

        <p class="code"><code>if (condition) { statement_1; } else { statement_2; }</code></p>

        <p>condition can be any expression that evaluates to true or false. See Boolean for an
          explanation of what evaluates to true and false. If condition evaluates to true, statement_1
          is executed; otherwise, statement_2 is executed. statement_1 and statement_2 can be any
          statement, including further nested if statements.
        </p>

        <p>You may also compound the statements using else if to have multiple conditions tested in
          sequence, as follows:
        </p>

        <p class="code">
          <code>
            if (condition_1) { statement_1; }<br />
            else if (condition_2) { statement_2;}<br />
            else if (condition_n) { statement_n; }<br />
            else { statement_last; }
          </code>
        </p>

        <p>In the case of multiple conditions only the first logical condition which evaluates to true
          will be executed. To execute multiple statements, group them within a block statement
          ({ ... }) . In general, it's good practice to always use block statements, especially when
          nesting if statements:
        </p>

        <p class="code">
          <code>
            if (condition) { statement_1_runs_if_condition_is_true; <br />
            statement_2_runs_if_condition_is_true; } else {<br />
            statement_3_runs_if_condition_is_false;<br />
            statement_4_runs_if_condition_is_false; }
          </code>
        </p>

        <p>It is advisable to not use simple assignments in a conditional expression, because the
          assignment can be confused with equality when glancing over the code. For example, do not
          use the following code:
        </p>
        <p class="code"><code>if (x = y) { /* statements here */ }</code></p>

        <p>If you need to use an assignment in a conditional expression, a common practice is to put
          additional parentheses around the assignment. For example:
        </p>

        <p class="code"><code>if ((x = y)) { /* statements here */ }</code></p>

      </section>

      <section id="while_statements" class="main-section">
        <header>
          <h2>while statement</h2>
        </header>
        <p>A while statement executes its statements as long as a specified condition evaluates to true.
          A while statement looks as follows:
        </p>

        <p class="code"><code>while (condition) statement</code></p>

        <p>If the condition becomes false, statement within the loop stops executing and control passes
          to the statement following the loop.
        </p>

        <p>The condition test occurs before statement in the loop is executed. If the condition returns
          true, statement is executed and the condition is tested again. If the condition returns false,
          execution stops and control is passed to the statement following while.
        </p>

        <p>To execute multiple statements, use a block statement ({ ... }) to group those statements.
        </p>

        <p>Example: <br />
        The following while loop iterates as long as n is less than three:
        </p>

        <p class="code"><code>var n = 0; var x = 0; while (n &gt; 3) { n++; x += n; }</code></p>

        <p>With each iteration, the loop increments n and adds that value to x. Therefore, x and n take
          on the following values:
        </p>

        <ul>
          <li>After the first pass: n = 1 and x = 1</li>
          <li>After the second pass: n = 2 and x = 3</li>
          <li>After the third pass: n = 3 and x = 6</li>
        </ul>

        <p>After completing the third pass, the condition n &gt; 3 is no longer true, so the loop terminates.

          <h2>Function declarations</h2>
        </header>
        <p>A function definition (also called a function declaration, or function statement) consists
          of the function keyword, followed by:
        </p>

        <ul>
          <li>The name of the function.</li>
          <li>A list of arguments to the function, enclosed in parentheses and separated by commas.</li>
          <li>The JavaScript statements that define the function, enclosed in curly brackets, { }.</li>
        </ul>

        <p>For example, the following code defines a simple function named square:</p>

        <p class="code"><code>function square(number) { return number * number; }</code></p>

        <p>The function square takes one argument, called number. The function consists of one statement
          that says to return the argument of the function (that is, number) multiplied by itself. The
          return statement specifies the value returned by the function.
        </p>

        <p class="code"><code>return number * number;</code></p>

        <p>Primitive parameters (such as a number) are passed to functions by value; the value is passed
          to the function, but if the function changes the value of the parameter, this change is not
          reflected globally or in the calling function.

Hi @giefchicken,

I don’t know exactly what you asked for but as I see you are combining flex and grid. It’s easier to stick with one and find the problem that way. I believe your side can be cerated by using one of thes techniques.

If possible can you share your codepen.io link so we can see exactly what you mean?

Kind regards

I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (’).

Hi luhah001,

Thanks for the speedy reply!

Sorry i was a bit in the wind yesterday when i wrote that post haha. But my problem is as followed: I have created a media quarry to change the layout as per the example (navigation bar goes to the top and content goes below it) when the viewport width gets below 800px.

This layout change works fine but when i now try to navigate to one of the sections via the navigation’s bar anchors/links, i am redirected to the correct section but the section is partially blocked by the navigation bar.

I tried changing the position to absolute of the “main-doc” so that it sits below the navigation bar and tried playing with the overflow but to no avail.
My codepen: https://codepen.io/giefchicken/pen/bGwLRwg

You can reproduce the behavior by minimizing the window so that it smaller than 800px and then use the navigation bar to navigate to the sections.

I just also saw that the navigation bar doesn’t work in codepen when the screen size exceeds 800px for some reason . Not seeing this issue outside of the codepen environment.

What the display mixing is concerned, i know i can use only grid or flex to fulfill this exercise but for some reason i like using the grid to create the general layout and then use flex within those grid-areas .

Hi @giefchicken, i tried a lot of things but nothing is working for me. I have seen a lot of posts about what you were trying to do but couldn’t figure out what would solve the issue.

I did an easier example to find a way: for everybody to use:

HTML:

<html lang="en">

<head>

    <meta charset="UTF-8">

    <meta name="viewport" content="width=device-width, initial-scale=1.0">

    <link rel="stylesheet" href="styles_test.css">

    <title>Document</title>

</head>
<body>
    <nav class="navbar">
        <a href="#first">First</a>
        <a href="#second">Second</a>
        <a href="#tenth">Tenth</a>
    </nav>
<div class="content">
    <div class="first section" id="first">
        <p>TEST1</p>
    </div>
    <div class="second section" id="second">
        <p>TEST2</p>
    </div>
    <div class="third section" id="third">
        <p>TEST3</p>
    </div>
    <div class="fourth section" id="fourth">
        <p>TEST4</p>
    </div>
    <div class="fifth section" id="fifth">
        <p>TEST5</p>
    </div>
    <div class="sixth section" id="sixth">
        <p>TEST6</p>
    </div>
    <div class="seventh section" id="seventh">
        <p>TEST7</p>
    </div>
    <div class="eigth section" id="eigth">
        <p>TEST8</p>
    </div>
    <div class="nineth section" id="nineth">
        <p>TEST9</p>
    </div>
    <div class="tenth section" id="tenth">
        <p>TEST10</p>
    </div>
</div>
</body>

CSS:

body {
  display: flex;
  flex-direction: column;

}

.navbar {
  display: flex;
  flex-direction: column;
  padding: 20px;
  position: fixed;
  top: 0px;
  background-color: seagreen;
}

.content {
  padding-top: 100px;
}

.first {
  background-color: rgb(164, 164, 196);
  height: 100px;
  width: 100px;
}

.second {
  background-color: rgb(218, 119, 27);
  height: 100px;
  width: 100px;
}
  1. The body selector is selecting the test script and causing it to be on top of the header/nav. This is why you can’t click the links in desktop view. Put everything inside a container and give the body styles (except the margin removal) to the container instead.

  2. You do not have to use flexbox or Grid for the stacked view. You can just unset the display property (reset it back to default).

  3. For the scroll fix I was going to suggest using scroll-padding but for some reason, it didn’t really seem to work for me. So one option is the old top padding negative top margin trick (more options to look at).

@media (max-width: 800px) {
  .main-section {
    /* scroll position fix */
    padding-top: 273px;
    margin-top: -270px;
  }
}

@lasjorg thanks a lot
it works perfectly.
Can you explain the padding margin trick a bit further? I don’t get why that makes sense…

The padding-top is pushing the sections down. The negative margin-top is pulling them back up to close the gap the padding creates.

This only works if the sections do not have any background color as the padding of each section is actually overlapping the section that comes before it. But because the elements are transparent you can’t see the overlap.

The green is the padding as you can see it is on top of the previous section:

Here it is with a background color:

The link I gave has some more info and a few different techniques.
