html or css?

what is html and css and how are they used

[Andy H]

html is hypertext markup language, it is the basic language of the internet, which all we browsers read.
CSS is cascading style sheets, which is a technology for applying common styles to loads of pages rather than repeating style instructions in html.
The two co-exist and work off each other.
CSS is quite powerful, but when you talk about CSS positioning of objects then (for my small brain at least) it gets a bit daunting.

They are both web languages I guess you could say, but CSS is for styling pages rather than the content, which is HTMLs job (or the job of server-side scripts like PHP, perl, etc)

All depands on what you need to develop.
Search engine tend to like css design when it comes to presenting page for SEO reasons.
If you are just creating a simple non commercial site you will probably better off using html with no css.
