Style problem in docs with banners

[vokilam-d]

Actually there are 2 bugs:

1. When hovering on close button in the example of important banner, the cross icon stays white and becomes undistinguished from hovered background
2. Navigating to another page with opened Pinned banner leaves empty space

Steps to reproduce the behaviour:

1. Go to banners doc page
2. Scroll down to the end
3. Select checkboxes "Important?" and "Pinned?"
4. Click on "Show example"
5. Hover over close button of the banner
6. See error of white icon on white background
7. Navigate from left sidebar to another page of the docs
8. Scroll down a bit
9. See error of blank space left behind the banner

Expected behavior I'd expect to not have this bugs:)

Opening an issue, you recommend using labels, but it seems that I cannot select them - maybe have no rights to do so?

I wanted to put bug and docs

Thanks for filing! Much to clean up here. Not sure what's going on with the labels, I'll look into that as well. :v:
