i want a scrollbar when the post is too long

Hmmm … that could be related to an overflow statement in the CSS for the item you want to have scroll bars on.

An example would be a bit more helpful … are you having this issue with your blog, or just trying to keep it in mind while creating a theme?

i want it to appear at my posts…so that the footer will be seen w/out going to the bottom of my page…how to put it?

@cais – this is a great solution!

@themanfromph – I just tested it and it works.

In style.css of the theme, there is the content class, most likely as
.entry-content (if you can’t find it, post your URL)
add the overflow property, also by setting a desired height, like this

height: 600px;
overflow: scroll;

Add some padding too, so the scroll bar is not too attached to the text

height: 600px;
overflow: scroll;
padding: 10px;

What about people with larger monitors?…

There’s a reason most people use dynamic height.

NOTE: overflow: scroll; will generate scrollbars regardless of whether the content exceeds the height or not..

Use overflow:auto and you’ll only get the scrollbars when the content warrants them.

i can’t see .entry-content in my style.css
here is my BLOG

Add it to .articleContent
t31os_ is right, use overflow: auto; (instead of scroll)

nothing happens…

I tested again and it works. Make the height to 400px to test, since some posts are shorter than 600px. Adjust the css accordingly.

.articleContent {
	width: 570px;
	padding: 10px 15px 0 15px;
	background: url('images/articleBg.png') repeat-y;
        height: 400px;
        overflow: auto;
}

it now workded… tnx…
how about putting color on it so its more attractive at Internet Explorer

Replace
background: url('images/articleBg.png') repeat-y;

with
background-color: #F5F5F5;

and pick your color from these css color values:
