Rounded Corners with CSS and JavaScript by Simon Willison
Rounded corners are one of the most frequently requested CSS techniques. As with many things in CSS, there are various ways in which this problem can be approached. In this article, I’ll look at the pros and cons of some common techniques and introduce a new technique that utilises both CSS and JavaScript.
Rounded Corners without Images: A Nifty Corners Inspiration
What is it all about? It’s a method of creating rounded corners of an element without using images, just with a piece of JavaScript and few drops of CSS. I like rounded corners, but the necessity to create for every diameter and every combination of foreground and background color 4 images for me as the designer and to download them for the user makes me use the square ones in most cases.
CSS Design: Creating Custom Corners & Borders by Søren Madsen
We’ve all heard the rap:
“Sites designed with CSS tend to be boxy and hard-edged. Where are the rounded corners?â€
Answer: the rounded corners are right here. In this article, we’ll show how customized borders and corners can be applied to fully fluid and flexible layouts with dynamic content, using sound and semantically logical markup.
Rounded Corner Boxes the CSS3 Way by Andy Budd
If you’ve been doing CSS for a while you’ll know that there are approximately 3,762 ways to create a rounded corner box. The simplest techniques rely on the addition of extra mark-up directly to your page, while the more complicated ones add the mark-up though DOM manipulation.

http://www.airtightov.com/lab/airtight_corners.html
Thanks for the list. I’ve been search for something like this for ages!
The airtight OV link is dead.
I recently had a need for rounded-corner boxes that work over a patterned background and from what I could tell none of the ones listed here allow for that, at least not any of the pure css ones. So I came up with my own solution that seems to work pretty well which you can view here:
http://nuttersmark.com/blog/web-development/-super-fantastic-resizable-pattern-friendly-css-rounded-corners
There’s a couple nifty helper methods to clean it up and neatly package everything too if your a Rails developer like myself. Cheers.
Jael,
This is probably 6 months too late but you could always use one the options that uses images and simply convert 3 of the images so they are proper corners, leaving your one rounded corner.
For gradients and round corners there is a new player out there:

Thanks a lot for so much information. I’ll be sure to share this.

Great list, thanks for compiling.
Good resource for beginners of web design and development.
I appreciated this tutorial. I will definatly put this into practice for my website.
Thanks.
Just wanted to point out that now some of the tasks involving creating rounded corners can be automated with XHTML/CSS generator called Artisteer. There are many cool types of content blocks with rounded corners, as well as the page design itself can have rounded corners. The corner graphics is created automatically so you don’t need an image editor.
Cheers
John
very nice collection. You might also want to add this: http://corpocrat.com/2008/09/13/css-tutorial-design-round-corner-boxes-in-css/
Here’s another technique to put on the pile. This one uses pure CSS3 in Safari and Firefox, no images. In IE, it uses corner images, at least until IE gets its act together… The same HTML is used in both cases.

Really help full… Good Stuff & information.
I wrote an article on how to create widget windows with rounded corners, drop shadow and gradiented backgrounds. It uses only CSS and images and is compatible with all browers. I think using images is better than the JavaScript solutions, I tend to put my PSD files under source control, that way you never lose the original file so making changes is pretty straight forward.
http://thatguynamedandy.com/blog/css-widget-rounded-corner-gradient-drop-shadow
Any feedback on my solution would be most appreciated.
Hallo.
You forgot about BlueBodens method, found at http://brugbart.com/Examples/Bordertechnique.html

Lean and Clean CSS boxes is my Favorite, you have a great list.

You can have a look as well at FlexiPanels CSS – a Dreamweaver extension that creates rounded corner css boxes starting from a picture.
Great post. Thanks!
Exremtley helpful article, please write more.
All of the above techniques are great. I prefer using some jQuery plugin for rounded corners.
OK, OK. I didn’t realize rounded corners were such a big deal but they are.
Below is a list of the submission urls for RSS and blog directories that you can submit your blog or RSS feed to
CSS3 has introduced ‘border-radius’ which allows the browser to render rounded corners =)
Nice Tutorial.
Some great advice here. Loved this article.
I’ve recently found the site http://www.cutmypic.com to be rather useful when not wanting to use css to round corners. It let’s you specify how round you want your corners to be, it’s pretty fast, and I don’t have to load up Photoshop to do it.
Good article. Thanks

Thanks for the multy style css curve box.Really great to learn.
Why people go to such lengths to get round corners using some overcomplicated methods just to stay “100% div/css”?
Have they all forgot KISS rule?
Why not using css driven table nested inside of whole div layout for these layout elements which need round corners?
In this respect table has everything divs lack.
It helps with:
- older browser compatibility (pretty much no issues, if css used is clean)
- dynamically spanned connector images (small image connecting corners)
- no problem with added content to one cell versus neighbour(s) – table always keeps expanded cell aligned to its neighbours
- very spatially clean layout – no need for dozens of overlapping divs driven by complex css, giving most of us a good head spin to visualise it
- no problem with 100% widths
- no problem with 100% heights
- no problem with keeping bottom cells on the bottom – same goes in general order of other table elements
- taking advantage of css properties – yes! you can use classes and ids (etc) here as you would with divs
… and above just for starters …
So … until css3 techs are used by browsers wide and far … wouldn’t you say that turning into “div/css zealots” does not help anyone here?
tis is fine and helpful site
Just what I need.
Hi!
Thanks for the links, this page helped me find exactly what I needed!
I did notice however, that not all of the links on the page go to articles. Some point to parked pages full of advertising links with nary a word on the subjects of CSS, JavaScript, or Rounded Corners. So perhaps it’s time to check & update the links?
Thanks again for the info!!
