CSS - margin and float property
- by David Casillas
1.- We have a div with static positioning. Inside we have a parragraph with a margin.
The heigth of the div will be the parragraph without the margin
2.- We have a div with float:left. Inside we have a parragraph with a margin.
The heigth of the div will be the parragraph plus its margin.
What is the explanation of this?
Here is the html code and the CSS code.
And here is a link to the test site.
