Copy the content of a div into another div

Question

I have two divs on my website. They both share the same css properties, but one of them holds 24 other divs. I want all of these 24 divs to be copied into the other div. Thi

Answer 1

Firstly we are assigning divs into variables (optional)

var firstDivContent = document.getElementById('mydiv1');
var secondDivContent = document.getElementById('mydiv2');

Now just assign mydiv1's content to mydiv2.

secondDivContent.innerHTML = firstDivContent.innerHTML;
