The integrations page had css in both `landing-page.scss` and
`portico.scss`. With this commit, the styles are mostly unified into
a single separate file.
Change the display from `block` to `flex` in order to be able to
arrange the elements as wanted. Reset the css of the header elements
only for the description view. Add `font-size: 1.2em` because the font
doesn't need resizing in this case, it needs resizing only when the
title is in the box.
Removed the `padding-bottom` from the `nav` on mobile because it
overlaps the new header and you cannot click the back button from the
integrations.
Fixes: #12365.
We remove the title from `errbot` integration documentation so that
all documentations have the same style. See
https://github.com/zulip/python-zulip-api/pull/515 for a similar
change to integrations where the docs live elsewhere in version control.
We also remove the `margin: 0` from the instruction tip because where
the tip is followed by a list, there is no space between the two; this
change doesn't mess up the other places where the tip is used.
This moves all the stylesheets like stats, billing etc. to another
directory called `static/styles/portico/`, matching the directory
structure of our JavaScript.
