5 Modern CSS Tricks That Changed Everything

CSS can be challenging for beginners, but a few key techniques can dramatically improve your web design skills.

In this post, I'll share five simple CSS tricks that transformed my designs from amateur to professional. These tips are easy to learn and can make a significant difference in your web layouts.

1. Shadows

Shadows can take your designs from flat and boring to shiny and professional in a matter of seconds. The trick is knowing how to use them correctly because no one likes overly used shadow.

A quick example:

/* Subtle box shadow */
box-shadow: 0 4px 6px rgba(0, 0, 0, 0.1); 

This will allow your elements to float effortlessly compared to this:

/* Over-the-top shadow */
box-shadow: 10px 10px 20px rgba(0, 0, 0, 0.5);

The former suggests professionalism, while the latter screams, "Ugly".

For text, text-shadow can also do wonders, but rather spartanly applied. Instead of full-blown neon glow effects, stick with something like this:

text-shadow: 1px 1px 2px rgba(0, 0, 0, 0.2); 

Pro tip: If you're struggling with making that perfect shadow, tools like CSSmatic can create beautiful presets that you can tweak to fit your design.

2. CSS Variables

If by now you aren't using CSS variables, it's never too late.

Let's say you're working on a site with a particular brand color. Instead of hardcoding colors, font sizes, or other commonplace values throughout your stylesheet, you assign them once and reuse them everywhere.

For example, instead of typing #3498db over and over again, you can declare them like this:

:root {
  --primary-color: #3498db;
  --secondary-color: #2ecc71;
  --font-family: 'Arial', sans-serif;
}

And from here on, you can use these variables anywhere:

button {
  background-color: var(--primary-color);
  color: white;
  font-family: var(--font-family);
}

h1 {
  color: var(--secondary-color);
}

The good thing about this is that when the brand management suddenly decides to change the color scheme (which usually does happen), you're able to change the color scheme from one point in style properties and the entire site will magically turn.

Also, CSS variables are great for toggling the theme. You want to add dark mode? Just redefine your variables depending on the class.

body.dark-mode {
  --primary-color: #222;
  --secondary-color: #555;
}

Once you start using CSS variables, you’ll find yourself wondering what you ever did before.

They really are a game-changer for clean, maintainable styles.

3. Animate and Transform Like a Pro

Now, adding a little liveliness to your designs will be the topic of discussion.

Animations serve more than just a chic decoration; they provide that sense of poise to the website.

But here's the thing: it need not be extraordinary! Simple stuff like a hover effect or slight movement can work really well.

For example:

button {
  transition: transform 0.2s ease-in-out;
}

button:hover {
  transform: scale(1.1);
}

So what is happening here?

The transition property makes the corresponding scaling transformation smooth; hence when you hover, this ensures a slight uptick in the button size rather than it just jumping at you.

Subtlety is key, but this makes for an intentional, professional peer-to-peer interaction.

Under the auspices of a move-the-style-up, let's add some keyframe animation:

@keyframes wiggle {
  0%, 100% { transform: rotate(0); }
  50% { transform: rotate(5deg); }
}

button {
  animation: wiggle 0.5s ease-in-out infinite;
}

Such animations would work well for drawing attention to certain elements: a "Submit" button or a call-to-action banner, for instance.

The trick is to keep it subtle. No one likes a website that looks like the 19s so stick to small, meaningful movements that redirect the user's attention.

4. The Effective Grid and Flexbox

Placing elements on a webpage has traditionally felt so damn hard but things started making sense with the advent of Flexbox and CSS Grid.

Using these features is like having cheat codes for your designs.

So, Flexbox. Let's suppose you're trying to center things. Instead of hacking around with margin: auto and float, you can simply write this:

.container {
  display: flex;
  justify-content: center;
  align-items: center; 
  height: 100vh;   
}

Flexbox is also excellent for evenly laying out items in a single row or column, and making your life much easier throughout the process.

Now, Grid. Grid is like Flexbox's overzealous sibling- ideal for more complex layouts. Want to build a gallery? A price list? With Grid, you're all set.

.container {
  display: grid;
  grid-template-columns: repeat(3,1fr);
  gap: 20px;
}

If space becomes limited, this will form three columns that adjust automatically. Want a column to be larger? Just edit the template.

grid-template-columns: 2fr 1fr 1fr;

Pro tip: Use both Grid and Flexbox for better outcome. You can use Grid for layout and Flexbox for individual components inside that grid.

Once you get know how to use flexbox and grid, you'll be able to whip up layouts that look like they took hours, all within minutes.

5. Pseudo-Elements

With ::before and ::after Pseudo element, you can finish your work with little extra detail that gives a Wow factor.

For example, if you want a fancy underline across a heading: instead of doing it with border or image, you can use ::after:

h1 {
  position: relative;
  font-size: 2rem;
}

h1::after {
  content: '';
  position: absolute;
  bottom: -5px;
  left: 0;
  width: 50px;
  height: 3px;
  background-color: #3498db;
}

You can also make it even better by pairing it with hover effect like this:

h1:hover::after {
  width: 100%;
  transition: width 0.3s ease-in-out;
}

Another great use case is applying decorative icons without cluttering your HTML.

button::before {
  content: '🚀';
  margin-right: 8px;
}

Now every button looks like it’s ready for launch, and you didn’t even have to touch the HTML.

Pseudo-elements allow you to freely experiment with creativity. For instance, you can use them to make shapes, overlays, or even animations that take your site to the next level!

The best part is that it preserve the cleanliness of your HTML while being fun in CSS.
