angular.js - Can I ask the master? Angularjs loads external html templates. How to solve the problem of flickering

Question

First explain. I asked different questions about {{}} binding data.
Phenomenon, the externally loaded HTML template has a style table, and every time you enter the page, the unformatted web content is always displayed.
It feels like the style sheet has not been loaded and parsed.

Answer 1

`<p ng-if="!aaa">
Loading...
</p>

<p ng-if="!!aaa">
You code
</p>`
