1. Use a Custom CSS Plugin or Child Theme

If you’re still editing the main style.css file in your theme, it’s time to make a change. When you update your theme, any changes you made there could be erased.

Instead, try one of these options:

  • Install a plugin like Simple Custom CSS, WP Add Custom CSS, or SiteOrigin CSS.
  • Use a child theme, which lets you keep your custom CSS separate from the main theme so updates won’t delete your work.

Child themes are especially helpful if you’re doing bigger design changes.

Pro tip: If you’re using a page builder like Elementor or Beaver Builder, many of them offer their own custom CSS boxes too. Just be careful—some page builders can add a lot of extra code.

2. Leverage Browser Developer Tools

Want to test something quickly on your site? Right-click on your page and click “Inspect.” This opens powerful tools like Chrome DevTools or Firefox Inspector.

With these tools, you can:

  • Test live changes before adding them to your files
  • Find and fix layout problems like spacing issues
  • Preview how your site looks on phones and tablets

Try this shortcut in Chrome: press Ctrl + Shift + M to simulate different screen sizes. It’s a fast way to check how your layout looks on other devices.

3. Learn Common WordPress CSS Selectors

Many WordPress themes use the same CSS class names. If you learn the common ones, you can work faster.

Here are a few you’ll see often:

  • .site-header – Space at the top of your site
  • .wp-block-image – Used for image blocks in the WordPress editor
  • .wp-block-button – Used for buttons created in the editor
  • .entry-content – The main area of a post or page
  • .widget and .sidebar – Used for sidebars and widgets like recent posts or categories

Knowing these terms can save you a lot of time when working with CSS.

4. Use CSS Variables for Consistency

If you’re reusing the same colors or fonts in your CSS, try using variables. For example, you can set your brand color once at the top:

:root {
  --primary-color: #0047AB;
  --accent-color: #FFD700;
}

Then, use the variable in your styles:

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

Benefits include:

  • Cleaner and simpler code
  • Consistent styles across your site
  • Easy updates—change one line, and it updates everywhere

5. Master Responsive Units and Media Queries

People use lots of different screen sizes. Make sure your site works great on all of them by using flexible units and media queries.

Try using these instead of pixels:

  • vw – viewport width
  • vh – viewport height
  • % – percent of a containing element
  • rem or em – sizes relative to text

Add media queries like this to change your layout depending on screen size:

@media (max-width: 768px) {
  .site-header {
    flex-direction: column;
  }
}

Making your site responsive helps with SEO and keeps your visitors happy.

6. Avoid !important With Better Specificity

The !important rule can force a style to apply, but using it too much leads to messy code. Instead of forcing a change, try writing better selectors.

Don’t do this:

.button {
  background: red !important;
}

Try this:

body.home .main-content .button {
  background: red;
}

Use !important only when absolutely needed, like when working with a plugin or theme that locks down styles tightly.

7. Organize CSS with Comments and Sections

A big CSS file is tough to work with if it’s one giant block. Add comments and divide your code into sections to keep it organized.

/* =====================
   Header Styles
===================== */

.site-header {
  background: #f5f5f5;
}

/* =====================
   Typography
===================== */

h1, h2 {
  font-family: 'Montserrat', sans-serif;
}

Adding comments helps you (and others) understand the code better, now and later.

8. Use Flexbox and Grid for Layouts

Forget using floats or inline-blocks. CSS Flexbox and Grid make layouts a lot easier.

Use Flexbox for layouts in one direction (like row or column):

.footer-widgets {
  display: flex;
  justify-content: space-between;
}

Use Grid for layouts in two directions (like columns and rows together):

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

Using Flexbox and Grid removes the need for extra divs and strange fixes.

9. Take Advantage of Preprocessors (SCSS)

If you’re handling bigger websites or building custom themes, using SCSS can save lots of time.

SCSS gives you:

  • Nesting – write CSS blocks inside other blocks
  • Variables – reuse values like colors
  • Mixins and loops – reuse groups of styles easily

You’ll need to compile SCSS into normal CSS using tools like Webpack or Gulp. Or, use an online tool if you prefer to keep it simple.

10. Minify and Optimize CSS for Performance

A faster site loads better, keeps visitors happy, and ranks higher in search engines. Minify your CSS before launching your site.

You can use:

  • Online tools like cssminifier.com
  • WordPress plugins like Autoptimize, W3 Total Cache, or WP Rocket

You can also inline the most important CSS (above-the-fold) so the page looks ready faster as it loads.

Bonus: Use Google PageSpeed Insights to find out how to make your site even faster.
