html5 - Are there any custom semantic html tags project for designing html pages? -

i found semantic ui project here: http://semantic-ui.com/

semantic structured around natural language conventions make development more intuitive.

for example bellow code creates menu using semantic:

<nav class="ui menu">   <h3 class="header item">title</h3>   <a class="active item">home</a>   <a class="item">link</a>   <a class="item">link</a>   <span class="right floated text item">     signed in <a href="#">user</a>   </span> </nav> 

instead of bootstrap css classes:

<div class="navbar">   <a class="navbar-brand" href="#">title</a>   <ul class="nav navbar-nav">     <li class="active"><a href="#">home</a></li>     <li><a href="#">link</a></li>     <li><a href="#">link</a></li>     <p class="navbar-text pull-right">signed in <a href="#" class="navbar-link">user</a></p>   </ul> </div>

my question is: there custom semantic html tags project designing html pages?

something this:

<menu>     <menu-header>title</menu-header>     <menu-item active="true">home</menu-item>     <menu-item>link</menu-item>     <menu-item>link</menu-item> </menu>
