用特定背景色做div的最佳方法？

Question

I need to create a div with specific background-color depending on variable object.

My options are:

1. Create an infinite css for each color.
2. Style in-line.

I know style should be separated from html. But, in this case, what is more efficient?

Answer 1

Do you need a different color based on dynamic content ("variable object")? In that case you should go for an inline-style. It would be easy for php/whatever backend you have to serve it conditionally.

While it's best to keep most styles on a stylesheet, there are exceptions to that rule. If your particular case asks for it, feel free to add your styles inline. For example, you need a gallery of things and you need the elements with a background-image instead of an img.

Answer 2

No, you cannot . The options you provided are the only way... You can do a complex/advance JavaScript / jQuery but it will always boil down to on how you will provide the selectors .
