Enclosing two smaller boxes within a larger box

Question

Enclosing two smaller boxes within a larger box

I'm attempting to replicate the layout shown in the desired.png file (specifically with an outer box surrounding two inner boxes).

Currently, my code doesn't display the expected outer box around the two inner boxes. How can I modify it to achieve the desired result?

Answer №1

Unlike some programming languages, CSS does not support the // comment format; instead, you can only use /* */. One common mistake is forgetting to specify the height of the parent container when using floating elements, as they do not affect the outer container's height. It's also crucial not to overlook setting the height of the inner container. Here's an example of how I would adjust the CSS:

#wrap {
    border: 1px solid red;
    height: 100px;
    width: 600px;
    padding: 5px;
}
#left_col {
    float: left;
    display: inline-block;
    width: 295px;
    height: 100px;
    border: 1px solid black;
}
#right_col {
    float: right;
    display: inline-block;
    width: 295px;
    height: 100px;
    border: 1px solid orange;
}

To resolve the issue, a simple solution would be to float the #wrap element. By doing this, it will wrap around any floated elements inside of it and adjust its height accordingly.

If floating the #wrap element is not viable for your layout, implementing a clearfix method can also solve the problem. There are various methods available to achieve this, as demonstrated previously.

From my perspective, if it makes sense semantically, using an hr element with clear:both in a CSS class could be a suitable option.

.clearer {
    clear:both; 
    visibility:hidden;
}

However, every developer has their own preference. Nowadays, utilizing content:after is considered a safe approach.

Answer №4

When using floats, remember that the height of an object will adjust to its content. If the inner divs have no content, nothing will be visible except for the borders.

It's important to make sure you understand .clearfix because floating elements within the #wrap without proper clearing can cause issues with height calculations in #wrap.

Here is a solution:

CSS:

#wrap {
    border:1px solid red;
    width:604px
}
.col {
    float:left;
    width:300px;
    border:1px solid black;
}

/* The Amazing clearfix */
.clearfix:before,
.clearfix:after {
    content: " ";
    display: table;
}
.clearfix:after {
    clear: both;
}

HTML

<div id="wrap" class="clearfix">
    <span class="col">
        Content!
    </span>
    <span class="col">
        Content!
    </span>
</div>
