    5. Forget <table>, try <div>

      One of the greatest advantage of CSS is the use of <div> to achieve total flexibility in terms of styling. <div> are unlike <table>, where contents are ‘locked’ within a <td>’s cell.

    1. Avoid Superfluous Selectors

    2. Sometimes your CSS declaration can be simpler, meaning if you find yourself coding the following:
        1. ul li { ... }  
      1. ol li { ... }  
      1. table tr td { ... }  
    1. They can be shorten down to just
        1. li { ... }  
      1. td { ... }  
    1. Explanation: <li> will only exist within <ul> or <ol> and <td> will only be inside <tr> and <table> so there’s really not necessary to re-insert them.

    2. Knowing !important

    3. Any style marked with !important will be taken into use regardlessly if there’s a overwriting rule below it.
    4. view plaincopy to clipboardprint?
      1. .page { background-color:blue !important;   background-color:red;}  
    7. In the example above, background-color:blue will be adapted because it’s marked with !important, even when there’s a background-color:red; below it. !important is used in situation where you want to force a style without something overwriting it, however it may not work in Internet Explorer.
