CSS3 brings with it some incredibly powerful styling features! The problem is that not all browsers support it, and many people/large corporations just haven’t updated their older browsers. Leaving a vast majority of people unable to view the content correctly.
As Internet Explorer has serious issues supporting CSS3 features so recently there have been great advances with attempting to gain support for the powerful styling features that CSS3 has including: Rounded corners, soft drop shadows, gradient fills, etc. These are the powerful elements that web designers and front-end website developers want to use to enhance the design of websites. They happen to also be difficult and time-consuming to implement, involving complex sprite images, extra non-semantic markup, large JavaScript libraries, and other hacks.
Here are a few fantastic tools you can use to make IE compatible with all these modern techniques to make the website design support these newer visual features.
