Browserhacks is an extensive list of browser specific CSS and JavaScript hacks from all over the interwebs. Special thanks to Paul Irish' comprehensive post and Nicolas Gallagher's additions.
- Pick the hack you want
- Copy it into your stylesheet
- Add the style you want between the braces
- Enjoy the new styles for the browser you targeted!
Please keep in mind using a hack is not always the perfect solution. It can be useful to fix some weird browser specific bug, but in most cases you should fix your CSS/JS.
Here is a little pen to fork and edit when we want to ask for people's help to test a hack: http://codepen.io/HugoGiraudel/pen/HEoJx.
