A html5 website and the usage of the article tag
This is a tool website that introduces html5-related technologies. The website itself is written in html5 | css3. Although it is worth learning for students with poor computer configuration, after all, html5 is the mainstream technology in the future.

I only noticed this website because of html5. There are too few domestic html5 websites, but there are few actual projects. The div effect implemented by html5 on this website is impressive: a front-end UI framework that can improve development efficiency by 500%!
I extracted the code, which is very simple, but it is also the charm of html5,Article

border-image use
with fallback css
Make sure to use all the right prefixes (-o-
, -webkit-
, -ms-
, -moz-
). Additionally, border-image.com may help. You should let this fall back to either a normal solid border or no border at all, depending on whether a border is essential for readability. We recommend that you avoid polyfills.
There were some syntax changes (requiring the fill
keywords) that may catch you off-guard; David Baron's border-image post describes the best course of action.
