Fascinating Facts About Web Development 🌍💻
1️⃣ The First Website Still Exists!
Tim Berners-Lee, the inventor of the World Wide Web, created the first website in 1991. You can still visit it here: info.cern.ch.
2️⃣ HTML is Not a Programming Language
Unlike JavaScript or Python, HTML is a markup language—it structures content but doesn’t perform logic-based operations.
3️⃣ JavaScript Runs Everywhere
Initially designed for web browsers, JavaScript is now used for server-side development (Node.js), mobile apps, AI, and even game development.
4️⃣ CSS Can Animate Without JavaScript
With CSS animations and transitions, you can create smooth effects without writing a single line of JavaScript.
5️⃣ The Web Has Over 1.5 Billion Websites
However, only about 200 million are actively maintained. The rest are inactive or abandoned.
6️⃣ Google Ranks Speed as a Factor
Websites that load faster than 2 seconds have a better chance of ranking higher on Google. Performance is key!
7️⃣ Most Users Leave a Slow Website in 3 Seconds
If your website takes too long to load, visitors will bounce—meaning they leave before interacting.
8️⃣ Mobile-First is the New Standard
More than 60% of web traffic comes from mobile devices, so responsive design isn’t optional—it’s essential.
9️⃣ Dark Mode Saves Battery
On OLED screens, dark mode can reduce power consumption by up to 60%, making it both stylish and energy-efficient.
🔟 Hackers Attack Every 39 Seconds
Security is crucial in web development. Using HTTPS, secure passwords, and firewalls helps protect websites from attacks.

Blocking text selection and screenshot functionality in HTML and CSS can be challenging, as users can always find ways around such measures, like using another device to take a screenshot. However, you can implement certain features to deter casual users from copying text or screenshots on your web page.
📚 Block Text Selection
You can use CSS to disable text selection. This can be done by applying the
Then, you can apply this class to the elements you want to protect:
📚 Block Right-Click Context Menu
You may also want to block the right-click context menu to further discourage users from copying content:
📚 Using a Transparent Overlay
You can use a transparent overlay that covers your content, which can help deter screenshot capturing:
And the associated CSS:
📚 Additional Considerations
1. Watermarking: If you are concerned about images, consider watermarking them to deter unauthorized use.
2. Web Application Limitations: Blocked actions are not foolproof; tech-savvy users will still find ways to bypass these restrictions. Blocking text selection or right-clicking may frustrate some users, as they may want to copy text for legitimate use.
3. Legal Notice: Consider placing a copyright notice or terms of service on your site, which legally protects your content.
4. JavaScript Disabling: Keep in mind that users can disable JavaScript, which would allow them to copy text as normal.
📚 Final Note
While these methods can make it more challenging to copy content, it's essential to remember that no solution is entirely foolproof. The best approach is often to accept that some level of copying may occur and focus on providing valuable, unique content instead.
📚 Block Text Selection
You can use CSS to disable text selection. This can be done by applying the
user-select property:.noselect {
-webkit-user-select: none; /* Safari */
-moz-user-select: none; /* Firefox */
-ms-user-select: none; /* Internet Explorer/Edge */
user-select: none; /* Non-prefixed version, currently supported by Chrome, Opera, and Edge */
}
Then, you can apply this class to the elements you want to protect:
<div class="noselect">
This text cannot be selected or copied.
</div>
📚 Block Right-Click Context Menu
You may also want to block the right-click context menu to further discourage users from copying content:
<script>
document.addEventListener('contextmenu', function(e) {
e.preventDefault();
});
</script>
📚 Using a Transparent Overlay
You can use a transparent overlay that covers your content, which can help deter screenshot capturing:
<div class="overlay"></div>
<div class="content">
This is the content you want to protect.
</div>
And the associated CSS:
.overlay {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
background-color: rgba(255, 255, 255, 0.5); /* Semi-transparent */
z-index: 10; /* Higher than content */
pointer-events: none; /* Let clicks go through */
}
.content {
position: relative; /* Keep it above the overlay */
z-index: 20; /* Higher than overlay */
}
📚 Additional Considerations
1. Watermarking: If you are concerned about images, consider watermarking them to deter unauthorized use.
2. Web Application Limitations: Blocked actions are not foolproof; tech-savvy users will still find ways to bypass these restrictions. Blocking text selection or right-clicking may frustrate some users, as they may want to copy text for legitimate use.
3. Legal Notice: Consider placing a copyright notice or terms of service on your site, which legally protects your content.

Chris’ Corner: PerformanCSS
How CSS relates to web performance is a funny dance. Some aspects are entirely negligible the vast majority of time. Some aspects are incredibly impactful and crucial to consider.
For example, whenever I see research into the performance of some form of CSS syntax, the results always seem to be meh, it’s fine. It can matter, but typically only with fairly extreme DOM weight situations, and spending time optimizing selectors is almost certainly wasted time. I do like that the browser powers that be think and care about this though, like Bramus here measuring the performance of @property for CSS Custom Property performance. In the end, it doesn’t matter much, which is an answer I hope they knew before it shipped everywhere (they almost certainly did). Issues with CSS syntax tend to be about confusion or error-prone situations, not speed.
But even though the syntax of CSS isn’t particularly worrisome for performance, the weight of it generally does matter. It’s important to remember that CSS that is a regular in the is render blocking, so until it’s downloaded and parsed, the website will not be displayed. Ship, say, 1.5MB of CSS, and the site’s performance will absolutely suffer for absolutely everyone. JavaScript is a worse offender on the web when it comes to size and resources, generally, but at least it’s loading is generally deferred.
The idea of “Critical CSS” became hot for a minute, meaning ship as little render blocking CSS as you can, and defer the rest, but that idea has it’s own big tradeoffs. Related to that, it absolutely should be easier to make CSS async, so let’s all vote for that. And while I’m linking to Harry, his The Three Cs: 🤝 Concatenate, 🗜️ Compress, 🗳️ Cache is a good one for your brain.
The times when CSS performance tends to rear it’s head are in extreme DOM weight situations. Like a web page that renders all of Moby Dick, or every single Unicode character, or 10,000 product images, or a million screenshots, or whatever. That way a

box-shadow just has a crazy amount of work to do. But even then, while CSS can be the cause of pain, it can be the solution as well. The content-visibility property in CSS can inform the browser to chill out on rendering more than it needs to up front. It’s not the more intuitive feature to use, but it’s nice we have these tools when we need them.Microsoft Edge Blog

Chris’ Corner: The New Web Safe
Back in the day I was a fan of the “Trebuchet MS” font. I didn’t like it large, but set fairly small I loved the look of it. Looked very website-ish — if that makes sense. https://blog.codepen.io/wp-content/uploads/2025/03/Screenshot-2025-03-17-at-11.11.49 AM-1024x396.png Honestly, at 12px, it still looks really nice.
The main reason I would use it is that it was considered a “web-safe” font, meaning most computers had “Trebuchet MS” installed and it would look more or less the same across those computers. On my latest-version macOS, I’ve still got it as a pre-installed system font. https://blog.codepen.io/wp-content/uploads/2025/03/Screenshot-2025-03-17-at-11.16.15 AM-1024x725.png I was thinking about this as Oliver Schöndorfer blogged about it recently. He points out that mobile operating systems changed the math on what is actually “web safe”.
Web-safe fonts system fonts that are pre-installed on most browsers and operating systems. While this was true 15 years ago, when you would find Arial, Times New Roman, Georgia or Verdana on Windows and Apple machines, this drastically changed with the mobile era.
Apparently none of the classic web-safe fonts are actually “web safe” anymore, which I suppose is ironic and kinda funny. I think designers have gotten more used to and OK with some differences in typography across browsers. Modern Font Stacks is a great resource for that. The whole point of a font stack is being cool with the actually used font being whichever one hits first in that list. The whole idea of
Along those lines, I think uifonts.app is a clever idea of looking at fonts in a very practical “app like” way. I like looking at beautiful typeface type specimens as much as the next fella but in the end it matters more what the typeface looks like on my boring thing not your fancy thing. https://blog.codepen.io/wp-content/uploads/2025/03/Screenshot-2025-03-18-at-4.50.25 PM-998x1024.png They should probably add

* It’s a modern miracle you can drop an image of typography onto a tool and it’ll tell you what fonts are used.

-webkit-font-smoothing: antialiased; but David Bushell almost has me convinced otherwise as 1) it’s macOS (very literally only) 2) it can make rendered fonts look closer to other operating systems, that is, thinner. My holdup is that I generally like thicker and it will be more consistent for users on that OS.
