android - What does -webkit-text-size-adjust do?

Question

I am trying to understand the use of -webkit-text-size-adjust:none;.

Adding/Removing that doesn't affect my font sizes on android (chrome) or iOS (safari and chrome). So what's the use?

Answer 1

-webkit-text-size-adjust

It specifies that if you(author) want's to resize the text when the browser page is zoomed. Most of the times it is better to set it to auto or 100% as the web browser will take care of how resizing of text is to be done.

Note : Mozilla devlopers page says its a non-standard

Interesting note : Developers using Twitter Bootstrap may be interested to know that Bootstrap uses ?webkit?text?size?adjust: 100% out of the box : Source Link

Edit

Chrome on android phones uses font boosting, so -webkit-text-size-adjust is being ignored no matter what value you set. You can disable font boosting it by setting max-height to something large(100000px or so) see this bug.
