Implementing Dark Mode with CSS

Chapter 1: Brighten up the Nights with Dark Mode
Hey there, future web developers! Let’s jump straight into coding stuff, the real fun part, shall we? Today, we’re going to tackle a cool trend that’s all the rage – Dark Mode. We’re not going over to the dark side just for fun, people often find it easier on the eyes, especially during night-time browsing.
Alright, enough chit-chat, let’s dive into the code ocean and ride some CSS waves.
(H2) What You Need to Know About Dark Mode
When we talk about a website’s look and feel, we’re usually referring to its color scheme, layout, and how it uses space. The right combination can create a crisp, clear, and enjoyable user experience. Dark Mode flips the script by swapping the light backgrounds and dark text we’re used to for an atmospheric, shadowy aesthetic.
Before we throw on our dark cloaks, remember – In the world of web development, great power comes with great responsibility. Yep! CSS stands for "Can’t Stop Smiling" because we’re about to pull off some coding magic.
(H2) The Magic Trick: The CSS media feature prefers-color-scheme
Here is where the trick starts. The "prefers-color-scheme" media feature comes to the rescue when we wish to implement dark mode. It helps to detect if the user has requested the system to use a light or dark color theme.
Now, let’s jazz up the scene with few CSS Diggy-bits!
(H3) Basic CSS Structure

css
body {
    color: #333;
    background-color: #fff;
}
@media (prefers-color-scheme: dark) {
    body {
        color: #ddd;
        background-color: #222;
    }
}

In the above code, our webpage is initially in light mode with a white background (#fff) and dark text (#333). But, "aha!", we’ve cleverly instructed the webpage to switch to dark mode with a dark background (#222) and light-colored text (#ddd) when the user prefers a Dark Theme. Just a simple switcheroo in the color scheme and voila, welcome to the dark side!
(H2) Proof of the Dark Pudding
Don’t you just love it when your code dances obediently to your tune? Well, let’s test our dark mode on various web browsers (Chrome, Firefox, Safari) and operating systems (macOS offering a system-wide dark mode setting since Mojave version, Windows since version 1809).
(H2) Final Strokes
There you go, ready to brighten up or darken down your websites with CSS. Now your website visitors can choose their preferred mode without feeling like a deer caught in the sudden dark!
Remember, your journey into the dark CSS realm has just begun. Keep exploring more profound and deeper into the abyss to discover more coding magic.
Until next time, keep coding, keep smiling, and keep lighting up the web, even in Dark Mode!
