Seems like according to <a rel= + "external noopener noreferrer" + target="_blank" + href= + "https://developer.mozilla.org/en-US/docs/Web/CSS/@media/prefers-color-scheme#browser_compatibility"> + the MDN</a> it’s been supported since 2019 for most browsers and + supported by all by now.</p> + <p>This is so wild!</p> + <h2>Why is this cool?</h2> + <p>Well you may have noticed this is in dark mode now (if you set your + preferences to dark in your OS/Browser). But this is cool because it + means we’re no longer restricted to using Javascript and custom + preferences for websites.</p> + <p>I had assumed this existed because sites like GitHub were defaulting + to darkmode despite me never setting anything in like my profile + settings. But I just assumed based off of my legacy knowledge this was + some custom render trick using javascript.</p> + <h3>Still no JS!</h3> + <p>I keep this blog JS free! While not all pages under the senders.io + umbrella are javascript free - everything in www.senders.io (this blog) + will always be.</p> + <p>I try to keep that, not only for my sake, but for your sake too - a + javascript free blog means the priority is reading.</p> + <h2>Examples</h2> + <p>So I achieve darkmode in this blog by doing the following:</p> + <pre><code>/* default / light */ +:root { + --background: white; + --font: black; + --quote: #eee; + --link: #0303ee; + --linkv: #551a8b; + --linkf: #f02727; + --articleborder: #060606; + --tableborder: #aaa; + --tablehead: #ebcfff; + --tablez: #eee; +} +@media (prefers-color-scheme: dark) { + :root { + --background: #1e1e1e; + --font: #eee; + --quote: #444; + --link: #00d3d3; + --linkv: #cd78f4; + --linkf: #f02727; + --articleborder: #23ed9b; + --tableborder: #aaa; + --tablehead: #6f5a7e; + --tablez: #313131; + } +} +</code></pre> + <p>Essentially, I leverage <a rel="external noopener noreferrer" + target="_blank" + href= + "https://developer.mozilla.org/en-US/docs/Web/CSS/Using_CSS_custom_properties"> + CSS Variables</a> to define the specific areas I set theme specific + colors (my nav bar is static regardless of dark/light mode for + example).</p> + <p>Then if the media preference is dark - I overwrite the variables with + my dark mode values!</p> + <p>Whats tricky is originally most of these values didn’t actually HAVE + values set - I relied on the system default for things like links and the + page colors in an effort to use minimum CSS as well.</p> + <p>I still feel like I am honoring that since I don’t have to duplicate + any actual CSS this way, I just have a lookup table of color values.</p> + <p>That being said my CSS file is still only about 3kB which is not so + bad. And I’ve actually covered most themed properties already - links, + tables, quotes.</p> + <h3>Toggling Themes</h3> + <p>Something else I found out during this experiment is you can actually + toggle the themes directly in your developer tooling. By opening your + devtools and going to Inspector (in firefox at least) there are two + buttons in the styles section “toggle light color scheme” and “toggle + dark color scheme” using a sun and moon icon.</p> + <p>This made testing VERY easy and actually is what I noticed to prompt + me into looking up if this was a standard CSS thing or not. So thanks + Mozilla!</p> + <h2>Conclusion</h2> + <p>Yeah if you’ve never realized this check out the MDN guides on both + variables (I didn’t realize these got put in the standard either!) and + themes!</p> + <ul> + <li>CSS Variables: <a rel="external noopener noreferrer" + target="_blank" + href= + "https://developer.mozilla.org/en-US/docs/Web/CSS/Using_CSS_custom_properties"> + https://developer.mozilla.org/en-US/docs/Web/CSS/Using_CSS_custom_properties</a> + </li> + <li>CSS Media prefers-color-scheme: <a rel= + "external noopener noreferrer" + target="_blank" + href= + "https://developer.mozilla.org/en-US/docs/Web/CSS/@media/prefers-color-scheme"> + https://developer.mozilla.org/en-US/docs/Web/CSS/@media/prefers-color-scheme</a> + </li> + </ul> + </article> + |
