Tips 1:
viewport, when your page has a width, for example, the width is 1000px, set width=1000, compatibility would be better.
Tip 2:
X-UA-Compatible, this attribute is only recognized by ie8 browser. It is a common application to let ie8 render in ie7 mode; like this: content="IE =7"; It would be a better suggestion not to use this meta, because after all, ie8....
Tip 3:
Expires: Document expiration time. After this time, you need to request it again from the server, and caching cannot be used; content="-1" theoretically disables caching. .
