For example, if I want to change the position of a DIV, what should I do? Write a top, margin, etc. Reply to the discussion (solution) In the tag body, write an extended CSS class, Such as <br> .margin-left-20 { <br> margin-left: 20px; <br> } <br> and then append to <div class="... margin-left-20"> <br> If “margin-left: 20px;” doesn’t work, use <br> “margin-left: 20px!important;” </p>
