[amelmr12]

**hello
I am working on the Technical Documentation Page challenge and I need your help guys I couldn’t figure out what m doing wrong

this tab opens when I click on a navbar element to the section that is linked to it (example of when i click on Introduction )
“Normally this link would bring you to another website! It works! This is a link to: (https: // www.freecodecamp.org/learn/2022/responsive-web-design/build-a-technical-documentation-page-project/build-a-technical-documentation-page#Introduction)”

it works on codepen but doesn’t when running the code in freecodecamp directly
here the link to my code https://codepen.io/gurrid/pen/QWQaJEy

I checked the course again and it does the same when trying to click on a navbar element https://www.freecodecamp.org/learn/2022/responsive-web-design/learn-accessibility-by-building-a-quiz/step-67

There is a small error, have you tried clicking on What you should already know and JavaScript and Java in the navbar. It doesnt work for me, check your href values for them.

thank u I fixed that but I still get the same tab that opens when I try on freecodecamp. org instead of codepen

I took a look at your code in codepen and one thing that got my attention on these 3 html tags for example

    <a id="Introduction" ></a>
     <section class="main-section"id="Introduction" >
       <header id="Introduction" >Introduction</header>

the Id attribute should be unique from each other, so I guess your issue is with the id name. Go through your code and find if you have duplicated Id name and change them so they are unique.
