Question

I want to create fluid layout using LESS and without using Bootstrap grid clasess like .span6 on html code. How can I do this?
When I wrote without LESS I create layout like this:

<div class="container-fluid">

<div class="row-fluid" id="header">
    <div class="span4 block">
        <h1 class="title">Sample Site</h1>
        <h2 class="sub-title">Powered by Twitter Bootstrap</h2>
    </div>
    <div class="span6 block">
        <ul class="nav nav-pills">
            <li class="active"><a href="#">Home</a></li>
            <li><a href="#">Pages</a></li>
            <li><a href="#">Typography</a></li>
            <li><a href="#">UI</a></li>
            <li><a href="#">Calendar</a></li>
            <li><a href="#">Tables</a></li>
        </ul>
    </div>
    <div class="span2 block">
        <div class="btn-group open">
            <button class="btn">Dropdown</button>
            <button class="btn dropdown-toggle" data-toggle="dropdown">
                <span class="caret"></span>
            </button>
            <ul class="dropdown-menu">
                <li><a href="#">Change password</a></li>
                <li><a href="#">Log in with another user</a></li>
                <li><a href="#">Change token</a></li>
                <li><a href="#">Log out</a></li>
            </ul>
        </div>
    </div>
</div>

<div class="row-fluid" id="slider">
    <div class="span12 block">
        <div id="myCarousel" class="carousel slide">
            <div class="carousel-inner">

Now, my layout looks next way:

<div id="wrap">
<div id="header">
    <div id="logo">SiteLogo</div>
    <div id="top-menu">
        <ul>
            <li><a href="#">Home</a></li>
            <li><a href="#">Page 1</a></li>
            <li><a href="#">Page 2</a></li>
        </ul>
    </div>
    <div id="logout">
        <a href="#">Logout</a>
    </div>
</div>
<div id="slider">

and what I should write on my .less file if I want to make div#wrap -> .container-fluid,
div#header -> .row-fluid, div#logo -> .span4, div#top-menu -> .span6, div#logout -> .span2
without writting this clasess on html code?

Answer 1

First, this wouldn’t really be semantic, at least, no more so.

The semantic form of <div id="top-menu"> is <nav> or <nav id="top">

The semantic form of <div id="header"> is <header>

In any case, there are instructions on doing this here:

Please stop embedding Bootstrap classes in your HTML

Honestly, though, it’s not as simple as the author makes it look. Just because you have a <nav> inherit the styles of .nav from Bootstrap doesn’t mean its children will inherit inherited styles as well.

So if I define a style from .nav ul, a <ul> element will not receive this style if it’s in a <nav>.
