Stop part of page being index by search engines? -

I can not stop how search engine indexing of your pages? Is there a HTML5 element for this?

This is just a line of text that I want to hide (no coworker should have his name on Google for some reason). Im wondering if I could text injected with JavaScript, but I've heard that Google sometimes looks JavaScript files

I also thought about using images instead of text, but It is worried how it will look at cross device and platform. Ive noted that text rendering Mac and may be different on PC and Ive already think about mobile devices, Retina display and more.

Thank you

until you can not hide until the content of those methods Which you have already mentioned above. Your best bet is to use Javascript in an external file and then block that file using robots.txt.
