how is the term 'echo "on" ' relating to css format?
Lucas Santos
19,315 PointsIt links to the CSS because you are using the echo command (which prints a word) inside the class of the element (where it would say class="<?php if ($section == "shirts"){echo "on";}?>"). So in your CSS you already have a class set to .on with some styling applied.
So in other words you print that word "on" into the class and setting it to the class of "on".

12,567 PointsIm understanding php, also understanding html and css really good. But echo "on" i would imagine would just print out 'on' on the page, so how does it link to css?
