How to make navigation remain at the top and fixed


Hello coders, I am unable to make the navbar remain fixed to the top as well as page.tech3

when i click on the nav-link, the #main-doc jump to occupy the #navbar
Please Help me resolve this.

Have you tried to review the challenges or search in google how to do that?

If you want the navbar to stay at the top of the screen (assuming yes) then add this:

#navbar {
...
position: relative;
top: 0px;
left: 0px;
width: 100%;
...
}

i have tried some if these but didn’t worked.

You said you want the bar fixed to the position in respect to the browser window, right? With the position property and the right keyword, and then writing that position using the left/right/top/bottom rules you can

Read this section from the article I posted.

  1. Fixed

Like position: absolute , fixed positioned elements are also removed from the normal document flow. The differences are:

  • They are only relative to the <html> document, not any other parents.
  • They are not affected by scrolling .

Here in the example, I change the orange box’s position to fixed , and this time it is relative 5px to the right of the <html> , not its parent (container).

I would also review the section 5. Sticky for a potentially even more elegant solution. Let me know if you need more help. But I may need to see your HTML to be of any further help.

sure, how can i share the file with you?

Can you copy and paste your code here? Or put it in a code pen pen and link to it.

In your original post, you only showed the css

JS Documentation introduction

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>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>

        <header>what you should already know</header>
        <p>This guide assumes you have the following basic background:</p>
        <ul>
            <li>A general understanding of the Internet and the World Wide Web (WWW).</li>
            <li>Good working knowledge of HyperText Markup Language (HTML).</li>
            <li>Some programming experience. If you are new to programming, try one of the tutorials linked on the main page
                about
                JavaScript.</li>
        </ul>
    </section>
    <section class="main-section" id="javaScript_and_java">
        <header>javaScript and java</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>
    </section>
    <section class="main-section" id="hello_world">
        <header>hello world</header>
        <p>To get started with writing JavaScript, open the Scratchpad and write your first "Hello world" JavaScript code:</p>
        <code>funtion greetme(yourName) { <br>
                    alert("Hello " + yourName); <br>
                } <br>
                greetMe("World");
        </code>
        Select the code in the pad and hit Ctrl+R to watch it unfold in your browser!
    </section>
    <section class="main-section" id="variables">
        <header>variables</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 class="main-section" id="declaring_variables">
        <header>declaring variables</header>
        <p>You can declare a variable in three ways</p>
        <p>With the keyword var. For example,</p>
        <code>var x = 42</code>
        <p>This syntax can be used to declare both local and global variable.
            By simply assigning it a value. For Example,
        </p>
        <code>
            let y = 42.
        </code>
        <p>This syntax can be used to declare a block scope local variable see Variable scope below</p>
        <p>By simply assigning it a value. For example,</p>
        <code>x = 42</code>
        <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>
        <code>let y = 13</code>
        <p>This syntax can be used to declare a block scope local variable. See Variable scope below.</p>
    </section>
    <section class="main-section" id="variable_scope">
        <header>variable scope</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>
        <code>
            if (true) { <br>
            var x = 5; <br>
            } <br>
            console.log(x); // 5 <br>
        </code>
        <p>This behavior changes, when using the let declaration introduced in ECMAScript 2015.</p>
        <code>
            if (true) { <br>
            let y = 5; <br>
            } <br>
            console.log(y); <br>
            // ReferenceError: y is not defined
        </code>
    </section>
    <section class="main-section" id="global_variables">
        <header>global variables</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 class="main-section" id="constants">
        <header>constants</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>
        <code>const PI = 3.14;</code>
        <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>
        <code>
            // THIS WILL CAUSE AN ERROR
            function f() {};<br>
            const f = 5; <br>
            // THIS WILL CAUSE AN ERROR ALSO <br>
            function f() { <br>
            const g = 5; <br>
            var g; <br>
            //statements <br>
            }
        </code>
        <p>However, object attributes are not protected, so the following statement is executed without problems.</p>
        <code>
            const MY_OBJECT = {"key": "value"}; <br>
            MY_OBJECT.key = "otherValue"; <br>
        </code>
    </section>
    <section class="main-section" id="data_types">
        <header>data types</header>
        <p>The latest ECMAScript standard defines seven data types:</p>
        <ul>
            <li>Six data types that are primitive</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>
            <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>
        </ul>
    </section>
    <section class="main-section" id="if...else_statement">
        <header>if...else statement</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>
        <code>
            if (condition) { <br>
            statement_1; <br>
            } else { <br>
            statement_2; <br>
            }
        </code>
        <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>
        <code>
            if (condition_1) { <br>
            statement_1; <br>
            } else if (condition_2) { <br>
            statement_2; <br>
            } else if (condition_n) { <br>
            statement_n; <br>
            } else { <br>
            statement_last; <br>
            }
        </code>
        <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>
        <code>
            if (condition) { <br>
            statement_1_runs_if_condition_is_true; <br>
            statement_2_runs_if_condition_is_true; <br>
            } else { <br>
            statement_3_runs_if_condition_is_false; <br>
            statement_4_runs_if_condition_is_false; <br>
            }
        </code>
        <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>
        <code>
            if (x = y) { <br>
            /* statements here */ <br>
            }
        </code>
        <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>
        <code>
            if ((x = y)) { <br>
            /* statements here */ <br>
            }
        </code>
    </section>
    <section class="main-section" id="while_statement">
        <header>while statement</header>
        <p>A while statement executes its statements as long as a specified condition evaluates to true. A while statement looks as
        follows:</p>
        <code>
            while (condition)
            statement
        </code>
        <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:</p>
        <p>The following while loop iterates as long as n is less than three:</p>
        <code>
            var n = 0; <br>
            var x = 0; <br>
            while (n < 3) { <br>
                n++; <br>
                x +=n;<br>
            }
        </code>
        <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>With each iteration, the loop increments n and adds that value to x. Therefore, x and n take on the following values:</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 < 3 is no longer true, so the loop terminates.</p>

    <section class="main-section" id="function_declarations">
        <header>function declarations</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>
        <code>
            function square(number) { <br />
            return number * number; <br />
            }
        </code>
        <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>
        <code>return number * number;</code>
        <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.</p>

The above, there’s still not enough for me to go off of, or maybe I’m missing something. With specific issues like this, it can be a lot easier to get help by making a pen on CodePen or some similar website, and copying your code there for others to see. This sounds like it may be caused by an issue in your JS, but I can’t be sure without seeing all of your code in something like a CodePen pen.

For the title question, though, here’s a quick pen showing the “sticky” position property which makes navigation remain at the top and fixed. I hope it helps.
