I need you to show only 50% of the DIV’s BG, so? 

#coberturas legend{
    font-family: 'Open Sans', Arial, Helvetica, sans-serif;
    padding:10px 20px;
    display:block;
    position:absolute;
    bottom:0;
    box-sizing: border-box;
    background-color:rgba(55,57,62,0.8);
    width:320px;
    text-transform:uppercase;
    transition:all 0.3s;
    -webkit-transition:all 0.3s;

}

this div is superimposed on another;

    Could you also post along with your question the code you’re trying to do this with? And if possible add more details, because the question seems to be a little vague...

  • What exactly do you want to do? Who’s inside that div? Set a height with overflow:hidden; css does not solve? We need more details to help you

  • I will edit the post, with the code

  • era of this you were looking for @Gustavocardoso ?

  • I voted for reopening, issue 6 seems to have made clear the goal.

I don’t know if you want it to be 50% of div in terms of being horizontal, or if in terms of 50% being vertical. so I’m going to post here two possible ways to do this both ways.

This will be the supposed HTML to generate the 2 divs. The id container is included only to keep both divs filho within the div pai - container using the property position:relative; which you will see in the CSS code below after the HTML code example:

<div id="container">
    <div id="coberturas1"></div>
    <div id="coberturas2"></div>
</div>

If you’re looking to do this horizontally, the CSS will be: http://jsfiddle.net/v7ecw3ah/

#container{position:relative;}
#coberturas1 {
    background-color: rgba(55,57,62,0.8);
    width: 50%;
    height: 300px;
}
#coberturas2 {
    background-color: #efc94d;
    width: 50%;
    height: 300px;

    /* código para mostrar apenas 50% da div Cinzenta (coberturas1) */
    position:absolute;
    top:5px; /* muda este valor para "0" - Isto foi apenas mostrar o que está a acontecer por detrás da div */
    right:25%; /* 25% significa metade (que neste caso será 50%) do tamanho de ambas as divs */
}

If you’re looking to do it vertically, the CSS will be: http://jsfiddle.net/v7ecw3ah/1/

#container{position:relative;}
#coberturas1 {
    background-color: rgba(55,57,62,0.8);
    width: 50%;
    height: 300px;
}
#coberturas2 {
    background-color: #efc94d;
    width: 50%;
    height: 300px;

    /* código para mostrar apenas 50% da div Cinzenta (coberturas1) */
    position:absolute;
    top:150px; /* 150px significa metade (que neste caso será 50%) do tamanho de ambas as divs */
    left:5px; /* muda este valor para "0" - Isto foi apenas mostrar o que está a acontecer por detrás da div */
}

  • This won’t help me, I need the div to still be there, but only show half, I mean the div will take up all the space, but the background needs to be half, I was wrong, I’m sorry

Being a "color" you can use linear-gradient

.horizontal .inner, .vertical .inner, .diagonal .inner {
    width:320px;
    height: 80px;
    margin: 0 0 10px 0;
}

.horizontal .inner {
    background: linear-gradient(to bottom, #00f 0%, #00f 50%, #f00 51%, #f00 100%);
}

.vertical .inner {
    background: linear-gradient(to right, #00f 0%, #00f 50%, #f00 51%, #f00 100%);
}

.diagonal .inner {
    background: linear-gradient(135deg, #00f 0%, #00f 50%, #f00 51%, #f00 100%);
}
<div class="horizontal">
    <div class="inner">
        Olá mundo
    </div>
</div>

<div class="vertical">
    <div class="inner">
        Olá mundo
    </div>
</div>

<div class="diagonal">
    <div class="inner">
        Olá mundo
    </div>
</div>

If you want compatibility with older browsers, use these properties:

/*Fallback para navegadores sem suporte*/
background: #00f;

 /* FF3.6+ */
background: -moz-linear-gradient(left, #00f 0%, #00f 50%, #f00 51%, #f00 100%);

/* Chrome,Safari4+ */
background: -webkit-gradient(linear, left top, right top, color-stop(0%, #00f), color-stop(50%, #f00), color-stop(51%,#f00), color-stop(100%,#f00));

/* Chrome10+,Safari5.1+ */
background: -webkit-linear-gradient(left, #00f 0%, #00f 50%, #f00 51%, #f00 100%);

/* Opera 11.10+ (não webkit/blink) */
background: -o-linear-gradient(left, #00f 0%,#00f 50%,#f00 51%, #f00 100%);

/* IE10+ */
background: -ms-linear-gradient(left, #00f 0%,#00f 50%,#f00 51%, #f00 100%);

/* CSS3*/
background: linear-gradient(to right, #00f 0%,#00f 50%,#f00 51%, #f00 100%);

/* Fallback para IE6 ao IE9 */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#00f', endColorstr='#f00',GradientType=1 );

You can use this online tool, more useful to emulate your div:

To generate the gradient I use this other online tool:

In your case it would look something like this:
