 * I am new to coding .
    I am using firebug to edit css , so the problem is after
   editing the Margin option in layout (firebug). i get this css
 *     ```
       element.style {
           height: 300px;
           width: 300px;
       }
       *, *::after, *::before {
           box-sizing: border-box;
       }
       ```
   
 * When i paste this css to my theme custom css option nothing happens .
    Am i copying
   the wrong css? Or I cant edit in custom css option

 * Hi, you can’t copy paste the firebugg css.
 * Why ? element.style doesn’t exist, it’s just style which is apply directly on
   the tag with firebug, to get the good result, you need to write the good selector,
   maybe something like this:
 *     ```
       div.mydiv {
           height: 300px;
           width: 300px;
       }
       ```
