My Html tab switch is not working, what am i doing wrong?

Question

I am trying to group my CV into section, by using the tabs 'Profile', 'Education', 'Skills'. 'Work Experience', 'Featured Projects'.

However, with the code snippets I have found and put together (and the help of W3schools), It seems that my tab functions are not working, but just list the Education "page" below the Profile "page".

What am I not considering? This is my first attempt with HTML and CSS. If you see any clean-up potential, please point it out.

Answer 1

Add this simple js function to switch the tabs. Also add one class (here tabcontainer ) in different tab containers. Add style display:none to next tabs initially, the style will be changed to display:block by js

 function openTab(tab) { var i; var x = document.getElementsByClassName("tabcontainer"); for (i = 0; i < x.length; i++) { x[i].style.display = "none"; } document.getElementById(tab).style.display = "block"; }

 <ul class="header_menu horizontal_list"> <li> <input id="tab1" type="radio" name="tabs" checked onclick="openTab('content_container1')"> <label for="tab1">Profile</label> </li> <li> <input id="tab2" type="radio" name="tabs" onclick="openTab('content_container2')"> <label for="tab2">Education</label></li> <li> <input id="tab3" type="radio" name="tabs" onclick="openTab('content_container3')"> <label for="tab3">Skills</label> </li> <li> <input id="tab4" type="radio" name="tabs" onclick="openTab('content_container4')"> <label for="tab4">Work Experience</label> </li> <li> <input id="tab5" type="radio" name="tabs" onclick="openTab('content_container5')"> <label for="tab5">Featured Projects</label> </li> </ul> <div id="content_container1" class="tabcontainer"> <div class="block"> <h1>Profile</h1> <blockquote class="profile_quote"> <p>"Tab 1: About Profile"</p> <p>Jiddu Krishnamurti.</p> <span class="entypo-quote"></span> </blockquote> </div> </div> <div class="clear"></div> <!-- Education CONTENT --> <div id="content_container2" class="tabcontainer" style="display:none"> <div class="block"> <h1>Education Timeline</h1> <blockquote class="profile_quote"> <p>"Tab 3: About Education Timeline."</p> <p>Test Author2</p> <span class="entypo-quote"></span> </blockquote> </div> </div> <div id="content_container3" class="tabcontainer" style="display:none"> <div class="block"> <h1>Skills</h1> <blockquote class="profile_quote"> <p>"Tab 3: About Skills."</p> <p>Test Author3</p> <span class="entypo-quote"></span> </blockquote> </div> </div> <div class="clear"></div>
