3 Responsive DIV Boxes Side by Side - Not Staying Together

Question

Hi i need help figuring this out. I have 3 divs that need to stay side by side regardless of how big or small the screen is, but the problem is that, once the screen's width reaches below 400px, then the last div goes under the others. How can I make them stay inline and at the same time responsive and centered without getting crazy with media queries? Please help. HERE'S A FIDDLE

CSS:

.box{
    background-color: coral;
    width: 30%;    
    float:left;
    margin:10px;
    border-radius:5px;
}
.text{
    padding: 10px;
    color:white;
    font-weight:bold;
    text-align:center;
}

HTML:

<div class="box">
    <div class="text">Text</div>
</div>
<div class="box">
    <div class="text">Text</div>
</div>
<div class="box">
    <div class="text">Text</div>
</div>

Answer 1

One way to fix this would be to wrap the divs in a container, and give that container a white-space:nowrap;text-align:center rule. Then change the divs from floating to display:inline-block;.

jsFiddle example

.box {
    background-color: coral;
    width: 30%;
    display:inline-block;
    margin:10px 0;
    border-radius:5px;
}
.text {
    padding: 10px 0;
    color:white;
    font-weight:bold;
    text-align:center;
}
#container {
    white-space:nowrap;
    text-align:center;
}

For a safer responsive layout, work with display:table on a wrapper div, and change the box to display:table-cell. For the padding, add a middle div, and set the width in percentual value. Also, you won't even need to set the box width.

HTML:

<div class="wrapper">
    <div class="box">
        <div class="text">Text</div>
    </div>
    <div class="middle"></div>
    <div class="box">
        <div class="text">Text</div>
    </div>
    <div class="middle"></div>
    <div class="box">
        <div class="text">Text</div>
    </div>
</div>

CSS:

.box{
    background-color: coral;
    display: table-cell;
    border-radius:5px;
}
.text{
    color:white;
    font-weight:bold;
    text-align:center;
    padding: 10px 0;
}

.wrapper {
    display: table;
    width: 100%;
}

.middle {
    display: table-cell;
    width: 10%;
}

The problem is with your fixed margin of 10px. Change it to percent value, and adjust the width percentual also, and it will work fine.

.box{
    background-color: coral;
    width: 28%;    
    float:left;
    margin:1%;
    border-radius:5px;
}
.text{
    padding: 10px 0;
    color:white;
    font-weight:bold;
    text-align:center;
}

Use table-cell

and have a container to be set to 100%:

.core {width: 100%; display: table; border-spacing: 10px;}

.box{
    background-color: coral;
    width: 32.03125%; 
    float:none;
    display: table-cell;
    border-radius:5px;
}
