* Make all containers 1fr An unintended consequence of changes made to containers in v0.21.0 (#2377) is something like #2385 so this commit sort of rolls that change back, and solidifies how containers are styled by default in respect to their width and height. Where appropriate the dimensions will be 1fr. * Make the DEFAULT_CSS of ProgressBar less greedy It was attempting to style a Vertical that is uses, but in doing so was styling all Verticals rather than a Vertical within a ProgressBar. This fixes that. * Update the CHANGELOG for the container changes * Move the ProgressBar CHANGELOG entry into the next release section * Link the container change entry in the CHANGELOG to its PR Now that the PR is PRd and we have a PR

About
Textual adds interactivity to Rich with an API inspired by modern web development.
On modern terminal software (installed by default on most systems), Textual apps can use 16.7 million colors with mouse support and smooth flicker-free animation. A powerful layout engine and re-usable components makes it possible to build apps that rival the desktop and web experience.
Compatibility
Textual runs on Linux, macOS, and Windows. Textual requires Python 3.7 or above.
Installing
Install Textual via pip:
pip install "textual[dev]"
The addition of [dev] installs Textual development tools. See the docs if you need help getting started.
