WTH: Mobile views don't have consistent gutters

The mobile frontend has no space between the cards and the edge of the screen which is inconsistent with settings pages and looks a bit weird. Left and right padding is removed on hui-view when screen is less than 500pixels wide.

@media (max-width: 500px) {
:host {
    padding-left: 0px;
    padding-right: 0px;

Settings pages have a 20px padding on both sides of the content (not all pages are consistent).

.content {
    max-width: 1040px;
    padding: 28px 20px 0px;
    margin: 0px auto;

A theme variable for content padding could be added to make this consistent everywhere. Something like --app-content-padding
