Liquid CSS rounded corners CSS

Posted on 2010-09-23

I need to modify a css in order to get a liquid rounded corner (top only) effect using a longer (compared with the box dimension) png image with both sides rounded.
Unfortunatelly I have poor to no possibility to modify the HTML, so I need to do everything by css.
This is the css code I am actually using
    margin-bottom: 15px;
	padding-bottom: 5px;
	padding-left: 0;
	color: #FFFFFF;
	background: transparent url(images/BlockHeader.png) no-repeat bottom right;

.block .title
	font-size: 0.9em;
	font-weight: bold;
	text-transform: uppercase;
	padding: 7px 10px;
	color: #ff9933;
	background: transparent url(images/BlockHeader.png) no-repeat bottom right;

.block .listbox
	font-size: 11px;
	padding: 5px 10px 10px;
	line-height: 18px;
	background-color:#404040 ;
	margin: 0px;

.block .listbox ul
	margin: 0px 0px 0px 0px;
	padding: 0px 0px 0px 10px;
	color: #3664A5;
	background-color: inherit;

.block a
	color: #FFF;
	font-weight: bold;
	text-decoration: none;

.block li
    list-style: none;

.block li.separator
	height: 1px;
	line-height: 1px;
	background: #ff9933;
	width: 140px;
	font-size: 1px;
	margin: 5px 0 5px 0;

.block-category-navigation, .block-manufacturer-navigation, .block-recently-viewed-products, 
.block-info, .block-shoppingcart, .block-newsletter, .block-livechat, .block-popular-tags,
.block-popular-blogtags, .block-blog-archive

Open in new window

This is a box example:
<div class="block block-info">
    <div class="title">
    <div class="clear">
    <div class="listbox">


Open in new window

As you can notice I would like to use the subclass (present in each box to sort out this problem.
Please help.

Most of the "rounding" tricks are actually done with a combination of CSS and the use of images.

A "curve" is essentially part of a circle.

Thus create an image of a circle (in whichever way you want it to look) and then use CSS to show only a section of that circle

Having said that, here are some tutorials that can help you:

Hello Gene,
thanks for your answer.
I took a look to the sample but both are using multiple images. I have the necessity to show only the left side and only the right side of the same image.
Thanks for supporting

Create a circle in photoshop or paint or Paint.Net (free downloadable paint with advanced settings)

Then using css show the top left "section" of that circle for the top elft corner and the top right section of that circle for the top right corner.

You can even "cut" that part u want to show within photoshop / paint itself and save it as an image.

I've used the sliding doors approach with a single, very wide (1600px) image which I think is similar to your goal here. You need to align the background image to opposite sides on the two elements and then set a right or left margin on one of the elements so that the rounded corner shows through from behind. Try something like this:
.block .title {
background: transparent url(images/BlockHeader.png) no-repeat bottom left;
margin: 0 6px 0 0;  /* adjust px value to show corner */
