Most web developers currently use vendor prefixes in CSS to enable certain features in some browsers. That’s fine, but sometimes I see code examples and prefix-adding tools that go a bit overboard with the support and add every possible prefix that has ever been in use (and sometimes even ones that were never used). I think there are a bunch of CSS properties that we can safely stop using vendor prefixes for, or at least considerably cut down on the number of prefixes.

Two different ways of creating a full-width navigation bar with vertically centered links whose entire height is clickable.
A responsive technique for making data tables (or any other element) wider than their parent horizontally scrollable.

Images that have dimension attributes in the HTML will retain their height when scaled down with CSS unless you add a height:auto declaration.
If you start seeing mysterious dots rendered on top of positioned elements in Firefox, check your text-overflow and z-index properties.
Sometimes you want to use different images when viewing a web page on screen and when printing it. One way of doing that is to use CSS generated content.
When you use an icon or other graphic instead of text for buttons, make sure there is real text for users who cannot see the image.
