我想查看其他人如何对他们的网站进行编码,但却试图理解这样做:
- <html class="js flexBox flexBoxlegacy canvas canvastext webgl no-touch geolocation postmessage no-websqldatabase indexeddb hashchange
- history draganddrop websockets rgba hsla multiplebgs backgroundsize borderimage borderradius Boxshadow textshadow opacity
- cssanimations csscolumns cssgradients no-cssreflections csstransforms csstransforms3d csstransitions fontface generatedcontent
- video audio localstorage sessionstorage webworkers applicationcache svg inlinesvg smil svgclippaths"
- lang="en" style="">
这是什么目的,有人可以向我解释一下吗?
