Technical Documentation Page - Build a Technical Documentation Page

Hi guys. I keep getting these two errors when running the tests on my code for the Technical Documentation Page project. I’ve checked the name of the headers and the id’s a million times and they are the same. Why wont it accept my code?
The errors:
1." 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."
2. “Each .nav-link should have text that corresponds to the header text of its related section (e.g. if you have a “Hello world” section/header, your #navbar should have a .nav-link which has the text “Hello world”).”

        <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).

          <br>
          <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>

        <p>JavaScript and Java are similar in some ways but fundamentally different in some others.

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>

Hello and welcome to the community :smiley:!
For the first issue:
your underscores should be in your childs text not your main section id. This applies to your second issue concerning your navbar too. Hope this helps.

Thank you for the idea but unfortunately it didn’t work, I tried replacing the spaces in my child’s text with underscores as you suggested but I keep getting the same errors…

Sorry, my bad. As for the second issue instead of matching your href link to the headers id it should match the text you have inside the header. In other words remove the underscores from your #navbars link. I hope this will solve the issue.

Didn’t work either, it must be bugged or something I just can’t understand what I’m doing wrong. I’ve spent over an hour and couldn’t find what I am doing wrong.

how did you change your code?

I tried both of the solutions starstruck suggested but they didn’t work so I changed it again to my first version.

You’ll want to paste your updated HTML in here so we can see exactly what you did. It’s not that we don’t believe you, but misunderstandings do happen :slightly_smiling_face:

To display your code in here you need to wrap it in triple back ticks. On a line by itself type three back ticks. Then on the first line below the three back ticks paste in your code. Then below your code on a new line type three more back ticks. The back tick on my keyboard is in the upper left just above the Tab key and below the Esc key. You may also be able to use Ctrl+e to automatically give you the triple back ticks while you are typing in the this editor and the cursor is on a line by itself. Alternatively, with the cursor on a line by itself, you can use the </> button above the editor to add the triple back ticks.

That’s how i changed it according to starstruck’s first suggestion. It didnt really made sense to me because now the text is displayed on the page with underlines instead of spaces between words, but I tried it anyways.

Yeah I’m sorry🙏 bro. I see that I was mistaken. Your header text shouldn’t have underscores. I think my second suggestion might be more on mark.

Should match the text and should also be without underscores.
Hope this helps.

@paul.calamusa2004, yalla it looks like there might be a bug in the step as another guy just posted having the same error.

That makes no sense. No underscores in normal view

Let’s look at the two HTML tests you aren’t passing:

“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.”

Now take a look at your second section:

<section class='main-section' id="What you should already know">
        <header>What_you_should_already_know</header>

Do you see how you have the requirements reversed? The header text should be “What you should already know” and the id on the section should be What_you_should_already_know.

“Each .nav-link should have text that corresponds to the header text of its related section (e.g. if you have a “Hello world” section/header, your #navbar should have a .nav-link which has the text “Hello world”).”

Once you fix the header text then you’ll want to fix the link text so it is exactly the same as the header text.

Also,

Do you see the issue here that will definitely cause you to not pass some tests.

You’ve got it here too.

You might want to run your HTML through a validator to help catch these types of errors.

What you are saying is exactly what I did in the first place, look at the code I first pasted when posting the problem, it is like you said it should be but it still doesn’t work. Anyway, I’ll paste it here one more time so you can see what I mean.

That’s what I thought as well, I just tried it for the sake of trying.

might be, it just doesn’t make sense why it wouldn’t work, ill try to run the code again tomorrow, thank you

yeah,

trouble in this is that you cant really go to anyone and say I’m gonna name this
Variable_scope and this is gonna look like that on your webpage.

The HTML you just pasted still has this problem. As I mentioned above, you should run your HTML through a validator to catch all of these problems.

I cant believed i missed it even when you pointed it out to me. It worked, thank you so much.
