What is causing this floating div to stay outside of its parent element?

Question

What is causing this floating div to stay outside of its parent element?

http://jsfiddle.net/hL8tvet8/

Look at the fiddle above.

In most cases, a floating element remains inside its parent element.

However, in this case it is not behaving as expected and I am unsure why.

I am trying to get the blue floating div to move into its parent green div.

Any idea why this floating div is not staying within the boundaries of its parent?

Shown below is an example code ( http://jsfiddle.net/hL8tvet8/ )

HTML :

<div class="header">
    <div class="left"></div>
    <div class="float_R"></div>
</div>

CSS :

.header {width: 200px; background-color: green;}
.left {width:50px; height: 50px; background-color: red;}
.float_R {width:50px; height: 50px; background-color: blue; float:right;}

Answer №1

Reorder the float_r and left elements. Remember, divs are block elements.

To view an example, refer to this fiddle: http://jsfiddle.net/hL8tvet8/4/

<div class="header">
    <div class="float_R"></div>
    <div class="left"></div>
</div>

Take a look at this response.

Check out the updated fiddle.

Here is the HTML code:

<div class="header">
    <div class="left"></div>
    <div class="float_R"></div>
</div>

And the CSS code:

.header {width: 200px; background-color: green;overflow:hidden;}
.left {width:50px; height: 50px; background-color: red;}
.float_R {width:50px; height: 50px; background-color: blue; float:right;}

(Why do I have to paste the code, so I can post a fiddle link? :-?)

In essence, parents of floated elements collapse, contrary to what you might have assumed. :(

To change the order of the two div elements, you can rearrange them as follows:

DEMO : http://jsfiddle.net/Vinyl/ctxsr2um/1/

<div class="header">    
    <div class="float_R"></div>
    <div class="left"></div>
</div>

Alternatively, you can insert a div with clear:both and apply float:left to the first div:

Answer №6

Following the placement of both floating child divs, it is important to clear the float effect by using clear:both;:

<div style="clear:both"></div>

UPDATED SNIPPET:

<div class="header">
    <div class="left"></div>
    <div class="float_R"></div>
    <div style="clear:both"></div>
</div>

FIDDLE UPDATE:

http://jsfiddle.net/ehsansajjad465/hL8tvet8/10/

If you want both divs to appear opposite each other, make sure to float the left div as well:

.left {width:50px; height: 50px; background-color: red;float:left;}

Answer №7

When using div elements, they will naturally stack on top of one another. To change this behavior, you can make them inline-blocks by adding the following CSS:

.header {
width: 200px;
background-color: green;
font-size: 0; /*added to remove unwanted bottom margin on inline blocks*/
}
.left {
display:inline-block; /*added*/
width:50px;
height: 50px;
background-color: red;
}
.float_R {
width:50px;
height: 50px;
background-color: blue;
float:right;
}

Answer №8

<div class="left"></div>

may be 50px wide, but it still creates a block box that forces the next element to appear below it.

For more information, check out: MDN Visual formatting model

When in the normal flow, within a block formatting context, boxes are stacked vertically one after the other.

To prevent this from happening, you can remove the first div from the normal flow by using the float property.
