Designing with CSS – Rounded Corners

The CSS3 border-radius property allows web designers and developers to create rounded corners easily in their design elements, without the need for corner images or the use of multiple div tags. At present boder-radius property enjoys widespread browser support.

If you are not very comfortable with CSS, or would like to have CSS codes auto-generated for you to save time, here is a useful and handy tool called CSS3 Generator. This simple tool created by Randy Jensen could be used for most basic design elements like rounder corners, box-shadow, text-shadow, etc on your webpages. It will create some cross-browser CSS3 code based on whatever values you want.

In this article I shall illustrate generation of code for rounded corners using border-radius property of CSS3 with the help of this tool. The procedure is simple. You chose your design element from the drop-down menu, enter your values, and get your auto-generated code for your project.

Example of Box with Rounded Corners

This example uses the CSS3 border-radius property and currently it will not work in all browsers. I am using this code on my blog as you could see various boxes with rounded corners like bread-crumb bar, search bar, author box.

CSS Code:

.box {color:#807970;background:#f9fafa;border:1px solid #dbe1e6}
.corner {border-radius:10px;-moz-border-radius:10px;-webkit-border-radius:10px}


<div class="box corner">
Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
Browser Support
This box created with border-radius property of CSS3 should have rounded corners at present for Safari (version 5 onward), Chrome (version 5 onward), Opera (version 10.5 onward) and IE9.

Mozilla Firefox (version 1.0 onward) supports border-radius with the -moz- prefix. However, it is only since version 3.5 that the browser has allowed elliptical corners. Prior to version 3.5, the browser only accepted one value per corner, resulting in corners with equal horizontal and vertical radii.

Safari and Chrome (and other webkit based browsers) have supported border-radius with the -webkit- prefix since version 3 (no longer needed from version 5 onward).

Even Microsoft have promised, and demonstrated in their recent preview release, support for border-radius from Internet Explorer 9 onward.

    • Modern browsers are adopting CSS 3. I am using CSS 3 where the features don't cause any problem with the browser. For example, rounded borders may or may not show up depending upon the browser but won't cause any problem.
