The height of div element is not setting automatically

                border:1px solid Gray;


If u run the above code in Jsfiddle, then it shows a border around the text
and the important thing is that
the height of the block class is auto
, so it automatically adjust its height.

But the problem comes when i added the following css :


Now the height of div.block
is not set automatically. Can anybody tell me the problem?

Now You need a Clearfix for it

content: ".";

html[xmlns] .clearfix {
display: block;

* html .clearfix {
height: 1%;

you add it like this

because float takes them out of the current flow. They are not inside the block div in the same way they where, use positioning and display:inline to get them to line up the way you want

You can use absolute positioning where by the outer element is set to height:auto and the inner #pe and #area are set to height:100%.

Have a look at this answer: How to make a floated div 100% height of its parent?

That’s because they’re not part of the common flow of the document anymore.

The solution could be to set display: block
in the block class and then use position: absolute
to position the element within that block by using left: 0
and right: 0

Just add overflow:hidden to class “block”.

   border:1px solid Gray;

Here is the fiddle:

I would add overflow:hidden
to the containing element ( #header
). That should fix it.

add float:left; in your block class.

Although a bit dirtier, you can also add something that clears both after the floated elements.

There are also cleaner “clearfix” variations of this as well, that will let you clear:both without adding non-semantic markup.
