Fixes#28526
* Removed `container` and `row-fluid` class from error pages.
* Use a variable for footer height.
* Made header sticky instead of fixed allowing us to position
page content without adding arbitrary padding or margin at top.
Header is around 60px in height, so reduced that much top padding
or margin.
This reverts commit eada57921e.
This does have CSS applied to it via webpack.
See
```
new HtmlWebpackPlugin({
filename: "5xx.html",
template: "html/5xx.html",
chunks: ["error-styles"],
}),
```
Since this file doesn't link any stylesheet, no CSS is applied to
these classes.
Tested change by pasting the content of it in `link_malformed`
and rendering that template using a malformed email confirmation link.
Ever since we started bundling the app with webpack, there’s been less
and less overlap between our ‘static’ directory (files belonging to
the frontend app) and Django’s interpretation of the ‘static’
directory (files served directly to the web).
Split the app out to its own ‘web’ directory outside of ‘static’, and
remove all the custom collectstatic --ignore rules. This makes it
much clearer what’s actually being served to the web, and what’s being
bundled by webpack. It also shrinks the release tarball by 3%.
