- Is the background #000 or #fff?
- Is the text color #000 or #ddd?
- Is the line height 100% or 500%?
- The background is #000 because the background value in css-important.css is !important; and therefore not overwritten by css-default.css
- The text color is #ddd because the text color value in css-important.css is !important; and therefore not overwritten by css-default.css
- The line height is 100% because the css-default.css line-height value overwrites the css-important.css line-height value because css-default.css was loaded after css-important.css
The last CSS file to be loaded is considered more important and overwrites previous CSS files, UNLESS !important; is added to the important values.
