The alignment of paragraph margins influencing the positioning of a floated block alongside it

Question

The alignment of paragraph margins influencing the positioning of a floated block alongside it

Dealing with margins has been quite a challenge for me lately. In the beginning of my markup, I have a div that is floated to the right.

 .grey{
   float:right; 
   width:200px; 
 }

My goal is to add some styles (background and margin) to the first paragraph that comes after this floated div.

 .blue{
    background-color: blue; 
    margin: 10px;
    overflow:hidden;
 }

Now, to prevent the background from extending under the floated div, I need to set "overflow: hidden" for the paragraph. However, I am facing two peculiar issues.

The margin doesn't seem to affect the side of the paragraph that touches the float;
The margin appears to affect the floated element next to it..

You can check out the issue in this fiddle: http://jsfiddle.net/whiteatom/Nkfzg/6/

Could someone help me figure out how to create margin space between the "Blue" element and the floated one? Also, any tips on removing these mysterious margins around my floated element would be greatly appreciated.

Thank you,

Answer №1

To create space between the paragraph and the floating element, you should add a left margin to the floating element:

.grey {
    float: right; 
    width: 200px; 
    margin-left: 10px;
}

The issue with margin collapse is that the top margin of the paragraph affects the overall body of the page instead of just the paragraph itself, causing it to push down both the paragraph and the floating element.

To resolve this problem, there are two options available (choose only one):

Prevent margin collapse by floating the body:
```
body {
    float: left;
}
```
By floating the body, the margin will only impact the paragraph. View updated fiddle
Add a negative top margin to the floating element:
```
.grey {
    float: right; 
    width: 200px; 
    margin-left: 10px;
    margin-top: -10px;
}
```
This adjustment shifts the floating element upwards to counteract the margin collapse while still maintaining its effect. View updated fiddle

If you want the .grey div to always be 200px wide, simply adjust the margin of the .blue div to be width + 10px. For example:

.blue {
    border: 1px solid red;
    background-color: blue;
    margin: 10px 210px 10px 10px;
};
