A sprite combines multiple background images into a single image. This is a technique for making web pages faster because it reduces the number of downloads in the page.

Background images make pages look good, but also make them slower. Each background image is an extra HTTP request. There’s a fix: combine background images into a CSS sprite. But creating sprites is hard, requiring arcane knowledge and lots of trial and error.

• Groups images into sprites

CSS3 brings with it some incredibly powerful styling features. Rounded corners, soft drop shadows, gradient fills, and so on. These are the kinds of elements our designer friends love to use because they make for attractive sites, but are difficult and time-consuming to implement, involving complex sprite images, extra non-semantic markup, large JavaScript libraries, and other lovely hacks.

As Internet Explorer has serious issues supporting CSS3 features and for those designers / developers who are facing such issues; Greepit previously shared couple of resources to add CSS3 support to Internet Explorer, checkout IE-CSS3 and Modernizr.

String is free, with no project limitations. Invite as many users as you like. You’re free to extract all your data, close your project at any time and you can easily import and export projects.

Google Browser Size is a visualization of browser window sizes for people who visit Google. For example, the “90%” contour means that 90% of people visiting Google have their browser window open to at least this size or larger.

This is useful for ensuring that important parts of a page’s user interface are visible by a wide audience. And designers can use this tool to get better insights and user experiences for their websites and applications.

In the above example image, there is a donate now button which falls within the 80% contour, meaning that 20% of users cannot see this button when they first visit the page. 20% is a significant number; knowing this fact would encourage the designer to move the button much higher in the page so it can be seen without scrolling.
