Common CSS text properties

[Lynuxen]

Description

Added inline support for common CSS text properties for <p>, <span> and <h> tags.

Current support:

Formatting a paragraph:

• text-align
• line-height
• margin-left
• margin-right
• text-indent

Formatting a run (can be used directly on a paragraph or header to format all runs)

• font-weight: ('bold', 'bolder', '700', '800', '900', 'normal', 'lighter', '400', '300', '100')
• font-style: ('italic', 'oblique', 'normal'')
• text-decoration: ('underline', 'line-through') ('solid', 'double', 'dotted', 'dashed', 'wavy'), and the longhand properties (text-decoration-*)
• text-transform: ('uppercase', 'lowercase', 'capitalize')
• font-size
• font-family
• color
• background-color: Paragraph and run highlight colors can now differ. Partial support on what can be used as a color.

Issue Reference

Fixes #47
Fixes #46.

There will most likely be a conflict with #44, as I started work before I noticed it and only saw it when creating this PR and checking the issues. I can rebase once #44 is merged or adjust as needed.

@Lynuxen The PR looks good! I’d like to better understand your approach regarding how the styles are being applied. There’s also a test failing on Python 3.14, so please take a look when you get a chance.

Additionally, please be aware that PR #44 conflicts with some of your commits. I’m giving priority to reviewing and merging whichever PR fully addresses the required changes and fixes first. You’re both doing great work, and I’m looking forward to merging your contributions to help the project grow.

@Lynuxen keep failing on Python 3.14, I re-run the job twice just in case, same results.
