You could simply store the text value in a variable to use wherever you want...

<div id="mainTitle>Watch Colors Live Online For Free</div>

Using jQuery and JavaScript, we initialize a new variable called title.

var title = '';

Now as soon as your text has been inserted into your #mainTitle div element, you can retrieve the text content of that div using this -

title = $("#mainTitle").text();

Your title variable is then available for you to use anywhere you want to copy that text -

$("#someElement, #anotherElement, #yetAnotherElement").text(title);

All three elements -

<div id="someElement">Watch Colors Live Online For Free</div>
<div id="anotherElement">Watch Colors Live Online For Free</div>
<div id="yetAnotherElement">Watch Colors Live Online For Free</div>

will now contain the same text as the first #mainTitle element.
