Question

I am trying to let the width of a div to be expanded according to its content horizontally
the content is a floating divs , I want them to appear as one row

I used white-space: nowrap; but it is not working on IE and FF ( It works very fine on google chrome )
here is my HTML code :

<div class="floating_menu_container">    
    <div class="floating_menu">
        <div class="floating_menu_item account">
            <div class="sub_floating_menu">
                <div class="sub_floating_menu_item"></div>
                <div class="sub_floating_menu_item"></div>
            </div>
        </div>

    </div>
</div>

and this is the CSS code :

.floating_menu_container{
position: absolute;
top: 25px;
left: 5px;
height: 50px;
z-index: 5;
}

.floating_menu_container .floating_menu{
height: 0px;
width: 40px;
background: #4D75A6;
z-index: -1;
position: absolute;
top: 35px;
left: 7px;
}

.floating_menu_container .floating_menu .floating_menu_item{
width: 30px;
height: 30px;
background: #94acc9;
border: 1px solid #6991c2;
margin: 7px 0px 4px 4px;
cursor: pointer;
position: relative;
}

.floating_menu_container .floating_menu .floating_menu_item .sub_floating_menu{
height: 30px;
position: absolute;
top: 0px;
background: #4D75A6;
left: 42px;
border: 1px solid #003980;
z-index: 10;
cursor: default;
white-space: nowrap;
}

.floating_menu_container .floating_menu .floating_menu_item .sub_floating_menu .sub_floating_menu_item{
width: 20px;
height: 20px;
background: #94acc9;
margin: 5px;
float: left;
cursor: pointer;
}

and here is the example on jsfiddle

I want to expand the div with class=’sub_floating_menu’ according to its content

Answer 1

Removing width: 20px; from your .sub_floating_menu_item, height: 30px; from .sub_floating_menu, and replacing float: left; with display: inline-block; should fix the issue, little demo: little link.
