Question

I would like to know if this is correct to set the bottom css using javascript:

var productElement2 = document.getElementsByTagName("footer");
productElement2.style.bottom=="0"

I ask this because my script does not work :p.
Thanks for the feedback :). If this is correct something else might be wrong but I just want to be sure.

Answer 1

Use the = operator for assignment. The == operator is for comparison.

productElement2.style.bottom = "0";

Note: If the value is a non-zero value, it needs a unit. Example:

productElement2.style.bottom = "10px";

Also, as kinakuta pointed out, the getElementsByTagName returns an array of elements, so you have to get one elements from the array. If you only have one footer, just get the first element:

var productElement2 = document.getElementsByTagName("footer")[0];
