What am i doing wrong?
it says " Each .main-section should have an id that matches the text of its first child, having any spaces in the child’s text replaced with underscores (_) for the id’s."

and

You should have the same number of .nav-link and .main-section elements.

Your code so far

      <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>
      <code></code>
      <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>

                <code>function greetMe(yourName) { alert("Hello " + yourName); }
            greetMe("World");

        <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>

For the first error:

Each .main-section should have an id that matches the text of its first child, having any spaces in the child’s text replaced with underscores (_ ) for the id’s.

And in your code I see this:

  <section class="main-section" id="What-you-should-already-know">

Reread that message and the code closely.

Remember that computers are very, very, vey picky, on a level that is hard for humans to understand. They are not good at, “well, I think I know what he meant” - we have to lower ourselves to their level.

See if you can apply that kind of thinking to the other issues. Check back if you get stuck.

Remember, every great coder is a great debugger. And great debuggers are great detectives.

ahh i see, thank you

it still says You should have the same number of .nav-link and .main-section elements.
ive counted those elements in page multiple times now and dont know what im missing

Use an editor to do the counting for you. Look for all occurrences of nav-link and compare to how many sections you think you have (often people write the wrong class on their elements so it is good to confirm you have not)

i pasted into vs code and ctrl + F to count how many i have and i have 5 of both. idk whats wrong with my code

when I check your code, the first error I see is

Each .main-section should have an id that matches the text of its first child, having any spaces in the child’s text replaced with underscores (_ ) for the id’s.

I think you should fix this one first?

i have 5 sections and 5 nav-links but it still says:
You should have the same number of .nav-link and .main-section elements.

please do not create duplicate topics on the same issue.
I have merged your duplicates.

I found a few syntax errors in your code.
When I fixed them, the code passed.

To see all the errors, paste the html into this online html validator:

thx for the help, was able to complete it
