It is easily done with:
-webkit-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
-o-user-select: none;
user-select: none;
-webkit-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
-o-user-select: none;
user-select: none;
Alternatively:
Let's say you have a <h1 id="example">Hello, World!</h1>. You will have to remove the innerHTML of that h1, in this case Hello, World. Then you will have to go to CSS and do this:
#example::before // You can of course use **::after** as well.
{
content: 'Hello, World!'; // Both single-quotes and double-quotes can be used here.
display: block; // To make sure it works fine in every browser.
}
Now it simply thinks it is a block-element, and not a text.
