Smaller breadcrumbs

Problem/Motivation

Breadcrumbs as a concept should mainly function as a means to navigate one or two levels up, and allow users to maintain awareness of their locations within the website, as originally intended and can be seen in its name "breadcrumb".

In my opinion, the breadcrumb link fonts are too big on drupal.org, since they push down the content, due to the large font size.

As an unintended consequence, documentation page titles might be kept a bit too short, to avoid the breadcrumb from ballooning, and taking over the screen. If that's the case, we should deal with the big fonts in the breadcrumb, if it leads to slightly truncated titles, for fear of the breadcrumb growing too big.

Current breadcrumb size

Suggested breadcrumb size, and <h1> padding-right removed

From https://www.drupal.org/about/core/policies/core-release-cycles/schedule.

Steps to reproduce

Visit the documentation page, and see that in may pages the breadcrumb breaks into multiple lines.

Proposed resolution

I tried reducing the breadcrumb font size to 1em, and it looks great:

.new-style .breadcrumb {
  font-size: 1em;
}

Also, there's a right margin in <h1> forcing titles to break over multiple lines. Perhaps it can be removed?

.node-type-guide h1, .node-type-documentation h1 {
  padding-right: 166px;
}

Remaining tasks

User interface changes

API changes

Data model changes
