I know that the alt="" attribute is recommended for SEO propososes, but I also heard that put the description inside a div and hide with text-indent:-9999px or font-size:0; is a good practice for SEO.

So there is any difference between use:

<img alt="Descripition" />

or

<div style="background: url('path/to/img')>Description</div>"

But must have an difference between an text inside a <div>," Jul 27, 2017 at 16:57

    Google reads your font-size:0 and thinks your are spamer:) Such technics is against guidelines - don't do it, not text-indent:-666, neither z-index:-666;. Write alt="" title="" - it should be enough.

For images that you want to get crawled use the <img> tag with a well-written altattribute that describes the image.

For background images solely used for design use the CSS background-image.

As far I know CSS rules will not add value to your sites SEO but if CSS is used to hide contents from users and is only visible to search engines that might hurt your sites SEO.
