问题 I know you can strip units from numbers in SASS when you know the unit before-hand like this: $number: 16px; $without-unit: 16px / 1px; @warn $without-unit; // 16 But is it possible to strip the unit from a number without knowing what the unit is first? @function strip-unit($number) { // magic code here... } @warn strip-unit(16px); // 16 回答1: -- UPDATE: You should never actually need to use this function. Sass math is very smart about units, and I have never seen a use-case in which stripping

问题 (Not to be confused with Xunit, a popular .Net unit testing library.) Today in a fit of boredom I started inspecting Gmails DOM (yes, I was very bored). Everything looked pretty straightforward until I noticed an interesting specification on the widths of certain elements. The illustrious Googlites had specified a number of table cols using the rare \'ex\' unit. width: 22ex; At first I was stumped (\"what\'s an \'ex\'?\"), then it came back to me: I seem to remember something from years ago

问题 I am designing a new website and I want it to be compatible with as much browsers and browser settings as possible. I am trying to decide what unit of measurement I should use for the sizes of my fonts and elements, but am unable to find a conclusive answer. My question is: should I use px or rem in my CSS?

问题 I heard you should define sizes and distances in your stylesheet with em instead of in pixels. So the question is why should I use em instead of px when defining styles in css? Is there a good example that illustrates this? 回答1: It is wrong to say that one is a better choice than the other (or both wouldn't have been given their own purpose in the spec).
