CSS: a piece of background of different colors?

I am trying to make a background cross browser implementation in 2 parts of each color.

Like this: http://imgur.com/l6ajF2q

To do this, I wrote the following code (script: http://jsfiddle.net/yrQAx/ ):

<!DOCTYPE html> <html> <head> <title>test</title> <style type="text/css"> .block { position: relative; background-color: #ddd; overflow: hidden; } .block .bottom-color { position: absolute; z-index: 999; top: 10%; left: 0px; width: 150%; height: 300%; background-color: #bbb; -moz-transform:rotate(173deg); -webkit-transform:rotate(173deg); -o-transform:rotate(173deg); -ms-transform:rotate(173deg); transform:rotate(173deg); filter:progid:DXImageTransform.Microsoft.BasicImage(rotation=1.73); } .block .content { position: relative; background: transparent; z-index: 1000; } </style> </head> <body> <div class="block"> <div class="content"> <h2>Lorem ipsum</h2> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Vestibulum lacinia, nibh nec cursus ultricies, est ligula tempus lectus, eget eleifend orci ipsum vitae velit. Proin mollis pharetra fermentum. Nullam sed semper nulla. Donec fermentum faucibus faucibus. Aenean rhoncus, mi viverra ultrices tincidunt, erat nibh auctor nisi, nec fermentum turpis orci euismod ligula. Sed eu tincidunt nunc, non molestie nisi. Nunc consequat, est in euismod consequat, libero justo laoreet lectus, id ornare ante tortor non magna. Fusce porta fringilla elementum. Maecenas pharetra nunc orci, ut facilisis ipsum iaculis ultrices. Vestibulum non odio eget enim pulvinar facilisis a ac nunc. Vestibulum sodales augue et lorem pulvinar bibendum id id turpis. Vestibulum blandit cursus imperdiet. Vestibulum venenatis massa diam, auctor pretium nisl rhoncus sit amet. Sed interdum metus tellus, id faucibus risus rhoncus vel. Duis tincidunt est quis justo suscipit pulvinar. Donec condimentum libero in turpis interdum, sed feugiat enim tempus. Vivamus a quam venenatis dui porta consectetur. Mauris ac scelerisque erat. Cras adipiscing purus a sem varius interdum ac sit amet nunc. Quisque iaculis ante nisl, non fringilla ante egestas eget. Sed sit amet est ultricies, commodo odio vitae, blandit justo. Fusce volutpat laoreet blandit. Mauris sapien arcu, sollicitudin quis porta non, rhoncus sed orci. Pellentesque faucibus neque at est ultrices dignissim. Quisque viverra, tortor ut feugiat aliquet, nisl nulla ullamcorper nisl, id laoreet dui turpis vel mi. Nunc sagittis, dui in posuere pharetra, libero nulla sollicitudin quam, venenatis imperdiet mi velit quis nibh. Pellentesque nibh massa, faucibus et nisl nec, ullamcorper tincidunt nibh. Proin iaculis commodo sapien, nec dapibus augue luctus eget. Praesent magna augue, semper non orci id, vehicula imperdiet justo. Nulla porta gravida euismod. Vestibulum ante ipsum primis in faucibus orci luctus et ultrices posuere cubilia Curae; Pellentesque vitae est egestas, dictum quam ut, semper nisl. Suspendisse ligula orci, tincidunt venenatis convallis eu, condimentum in nunc. Vestibulum mollis fermentum malesuada. Sed rutrum erat quis quam molestie condimentum. Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. Integer consectetur congue massa, eu viverra nisi tristique ut. Maecenas pulvinar eget sem in pharetra. Nulla malesuada ultricies eros, ac tristique massa pulvinar ut. Fusce mattis auctor leo, ut ultrices eros ultricies vel. Fusce ac augue nec mi congue sollicitudin at quis nisi. In nec venenatis arcu. Integer ac mauris dapibus, imperdiet nibh suscipit, venenatis arcu. Etiam hendrerit magna ligula, et sodales nunc imperdiet id. Praesent dapibus erat ac ipsum tempor fringilla. Fusce posuere massa sit amet elit porta, in facilisis ipsum dapibus. </div> <div class="bottom-color"></div> </div> </body> </html>

As you can see, it is based on the rotating div.bottom-color element, which is responsible for the second color. There is a big problem: whenever I change the size of the container ( div.block ), the second color can be lost altogether or the first color ( div.container background) is lost.

So my question is: how do I fix this? Or am I doing it wrong and should this effect be done in some other way?

It is best to use a gradient background. Of course, you will need to adjust the angle.

http://cssdeck.com/labs/xbmc9zum

 .content { background: #ebf1f6; /* Old browsers */ background: -moz-linear-gradient(-45deg, , #bbb, #bbb 20em, #ddd 20em); /* FF3.6+ */ background: -webkit-linear-gradient(-45deg, , #bbb, #bbb 20em, #ddd 20em); /* Chrome10+,Safari5.1+ */ background: -o-linear-gradient(-45deg, , #bbb, #bbb 20em, #ddd 20em); /* Opera 11.10+ */ background: -ms-linear-gradient(-45deg, , #bbb, #bbb 20em, #ddd 20em); /* IE10+ */ background: linear-gradient(135deg, #bbb, #bbb 20em, #ddd 20em); /* W3C */ }

Your solution is not compatible with a cross-browser. Instead, you should create a .png image that has one side triangle with dark gray. And make the other side 100% transparent, and let the background color be visible. The image you make will be large, but, fortunately, png images take only a few bytes when you use only 2 colors.

It is best to use cimmanon solution (gradients).

However, if you want your solution to work, see CSS

  top: 0px; right: 0px; width: 150%; height: 300%; background-color: #bbb; -moz-transform:rotate(-26deg); -webkit-transform:rotate(-26deg); -o-transform:rotate(-26deg); -ms-transform:rotate(-26deg); transform:rotate(-26deg); -webkit-transform-origin: top right; transform-origin: top right;

I added the beginning of the trandform of the top right. This way you rotate the div around this point. Also pay attention to the top 0px and the right 0px, which also position this point well (top right).

With these changes, the div will always be where you want.
