Do you need to disable text selection / text highlighting of your website without using any JavaScript code? If the answer is yes, add this CSS code into your website to prevent users selecting text of your website or blog.

body {
    -webkit-touch-callout: none;
    -webkit-user-select: none;
    -khtml-user-select: none;
    -moz-user-select: none;
    -ms-user-select: none;
    user-select: none;
}

If you are using blogger, add it just before ]]></b:skin>.

To understand how it works, try to select below text.

Hi, I am an unselectable text. If you are not sure, try to select me.
