You will never get the IE7 or IE8 rendering engine to achieve full compatibility with HTML5, CSS3, and other modern technologies. They are simply not capable of it.
However there are some hacks, tools and plugins which can get you part of the way.
Tools like Modernizr will help you by allowing you to detect which features are supported, to give your site a chance to work around it.
jQuery is a great library anyway, but is particularly good in this context because it abstracts a lot of browser differences away from the developer. Some things are easy in most browsers but a real pain in IE; jQuery takes a lot of that kind of stuff and makes it easy regardless.
Dean Edwards’ IE7.js and Selectivzr are both Javascript libraries that give IE support for lots of the CSS selectors which were missing in older versions. This allows you to write your stylesheets without worrying so much about what IE supports. (IE7.js also fixes a number of IE’s other glitches and missing features too)
CSS3Pie is a hack for IE that adds support for CSS
border-radius, gradients andbox-shadow.There are in fact a whole load of hacks along these lines, all aimed at adding features to older versions of IE which it is missing. Modernizr’s website has a big list of them here: https://github.com/Modernizr/Modernizr/wiki/HTML5-Cross-Browser-Polyfills
However there is one big caveat to all of this. Speed. IE<=8 is a slow browser. It has a slow Javascript engine. Virtually all of these hacks are javascript based. You might get away with running a few of them on any given site, but trying to use enough of them to give IE anything like full support for HTML5 and CSS3 will slow the browser down to the point of being unusable.
There is one other angle to approach this question though, and that’s Google’s Frame plugin for IE. This basically installs the entire Google Chrome browser engine into IE. The user is still running the IE shell, but the web page is rendered as it would be in an up-to-date version of Chrome.
This sounds great, but of course it isn’t perfect. The main down-side of it is that the end user has to install it manually onto their computer, which means that you as a web developer have no real control over whether it’s there or not. So its not something you can just add to your site and expect everything to magically work.
Finally, you may also be interested in CanIUse.com, which gives browser support tables for various features, allowing you to see at a glance what is and what isn’t supported in various versions of each browser.
