Hello, CSS!
Hello, CSS! is a CSS template which styles most elements to neutral and aesthetically pleasing defaults. I copy/pasted variants of this so often I figured I might as well put a cleaned up and annotated version somewhere.
I encourage you to pick ’n choose what you need, rather than insert everything.
Design principles
Good typography can help your reader devote less attention to the mechanics of reading and more attention to your message. Conversely, bad typography can distract your reader and undermine your message.
—Matthew Butterick, Practical Typography
- Pleasant defaults that should work well for most websites.
- Main focus is text and good typography.
- Simplicity matters: easy to extend or modify.
- Works on all browser, screen sizes, assistive technology, and when printed.
Example pages.
- demo/README.html (just base.css); demo/README-fancy.html (all files).
- My website, arp242.net.
- GoatCounter for both the public facing website as well as the backend (with quite a few additions, but Hello, CSS! as the base template).
- I reformatted The Art of Unix programming with this template.
- My CV.
Usage
There are several files, mix-and-match as you want.
There are only a few classes (see the table below); for the most part element
selectors are used (e.g. blockquote { .. } instead of .blockquote { .. }).
The files are brief and well annotated, and a number of styles have commented-out alternatives. I encourage you to read and modify to your preference, rather than blindly copy/paste.
Not every last element is styled. For some things – such as <abbr> – it’s fine to rely on the browser defaults, small differences are okay. Feel free to open an issue if you’re missing something in particular.
HTML example
A typical HTML page might look something like:
<body>
<nav class="center">
<a href="/">Home</a>
<a href="/weblog">Weblog</a>
</nav>
<article class="page">
<h1>Main content</h1>
<p>..</p>
<div class="postscript"><strong>Footnotes</strong>
..
</div>
<div class="postscript"><strong>Feedback</strong>
..
</div>
</article>
<footer class="center" style="text-align: right">
