Sorry, I'm late on https://github.com/symfony/symfony/pull/33613 and https://github.com/symfony/symfony/pull/33614 but I realized 3 minor visual issues:
 * the background color of the warning message for consistency should be `$lightColor()` and imho a little bit smaller.
 * the check icon has a very wide margin in relation to the edge of the rounded box:
![check-margin-before](https://user-images.githubusercontent.com/2028198/65379790-3ee95a00-dc9c-11e9-97d6-af6c10837c6d.png) vs ![check-margin-after](https://user-images.githubusercontent.com/2028198/65379810-b1f2d080-dc9c-11e9-8167-7ebbd0f92927.png)
 * and the resources (doc links) on wide screens have a very small space between them.

I've also removed some useless css classes (footer).
