Some useful CSS tricks

 

1. Centering an Element

Centering an element both horizontally and vertically can be easily achieved using Flexbox.


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

2. Customizing Scrollbars

You can style the scrollbars for a more personalized look.


/* WebKit browsers (Chrome, Safari) */ ::-webkit-scrollbar { width: 12px; } ::-webkit-scrollbar-thumb { background-color: #3498db; border-radius: 6px; } ::-webkit-scrollbar-track { background: #f2f2f2; }

3. Creating a Responsive Grid with CSS Grid

CSS Grid makes it easy to create responsive layouts.


.container { display: grid; grid-template-columns: repeat(auto-fit, minmax(200px, 1fr)); gap: 10px; }

4. Hover Effects with Transitions

Adding smooth transitions to hover effects can improve user experience.


.button { background-color: #3498db; color: white; padding: 10px 20px; border: none; transition: background-color 0.3s ease; } .button:hover { background-color: #2980b9; }

5. CSS Variables for Theming

CSS variables allow you to define and reuse values, making them great for theming.


:root { --primary-color: #3498db; --secondary-color: #2ecc71; --font-size: 16px; } body { color: var(--primary-color); font-size: var(--font-size); } h1 { color: var(--secondary-color); }

6. Text Overflow Ellipsis

To handle overflowing text within a fixed-width container, use the following:


.text-overflow { white-space: nowrap; overflow: hidden; text-overflow: ellipsis; width: 200px; }

7. Object-fit for Responsive Images

Ensure images cover the container without distortion.


.image { width: 100%; height: 300px; object-fit: cover; }

8. Creating a CSS Triangle

CSS triangles are useful for tooltips, dropdowns, and other UI elements.


.triangle { width: 0; height: 0; border-left: 10px solid transparent; border-right: 10px solid transparent; border-bottom: 10px solid #3498db; }

9. Overlay Text on an Image

Position text over an image using absolute positioning.

.container { position: relative; text-align: center; } .image { display: block; width: 100%; } .text { position: absolute; top: 50%; left: 50%; transform: translate(-50%, -50%); color: white; }

10. CSS Shapes with clip-path

Create interesting shapes with the clip-path property.


.shape { width: 200px; height: 200px; background: #3498db; clip-path: polygon(50% 0%, 100% 50%, 50% 100%, 0% 50%); }

11. Sticky Positioning

Make an element stick to the top of the viewport when scrolling.


.sticky { position: -webkit-sticky; /* For Safari */ position: sticky; top: 0; background-color: yellow; padding: 50px; font-size: 20px; }

12. Using CSS Counters

Create automatic numbering in lists.


.counter { counter-reset: section; } .counter h2::before { counter-increment: section; content: "Section " counter(section) ": "; }

13. Custom Checkbox and Radio Buttons

Style custom checkboxes and radio buttons.


/* Hide the default checkbox */ input[type="checkbox"] { display: none; } /* Create a custom checkbox */ input[type="checkbox"] + label { position: relative; cursor: pointer; } input[type="checkbox"] + label:before { content: ""; display: inline-block; width: 16px; height: 16px; background: white; border: 2px solid #3498db; border-radius: 3px; margin-right: 10px; } input[type="checkbox"]:checked + label:before { background-color: #3498db; }

14. CSS Gradients

Use gradients to create beautiful backgrounds.


.background { background: linear-gradient(45deg, #3498db, #2ecc71); }

15. Responsive Typography with vw

Use viewport width units for responsive font sizes.


.responsive-text { font-size: 4vw; /* 4% of the viewport width */ }

16. Dark Mode with CSS Variables

Easily switch between light and dark themes using CSS variables.


:root { --background-color: #ffffff; --text-color: #000000; } body.dark-mode { --background-color: #000000; --text-color: #ffffff; } body { background-color: var(--background-color); color: var(--text-color); }

17. CSS Filters

Apply visual effects like blur, grayscale, and brightness.


.image { filter: grayscale(100%); } .image:hover { filter: grayscale(0%); }

18. Smooth Scroll Behavior

Add smooth scrolling to your page.


html { scroll-behavior: smooth; }

19. Fullscreen Overlay Navigation

Create a fullscreen navigation overlay.


/* Overlay */ .overlay { height: 0%; width: 100%; position: fixed; top: 0; left: 0; background-color: rgba(0,0,0, 0.9); overflow-y: hidden; transition: 0.5s; } /* Overlay content */ .overlay-content { position: relative; top: 25%; width: 100%; text-align: center; margin-top: 30px; } .overlay a { padding: 8px; text-decoration: none; font-size: 36px; color: #818181; display: block; transition: 0.3s; } .overlay a:hover { color: #f1f1f1; } /* When the height of the overlay is 100%, show the overlay content */ .overlay.show { height: 100%; }

20. Advanced CSS Selectors

Use advanced selectors like :nth-child, :nth-of-type, and :not.


/* Select every second element */ li:nth-child(2n) { background-color: #f2f2f2; } /* Select every third element of type */ li:nth-of-type(3n) { font-weight: bold; } /* Select all but the first element */ li:not(:first-child) { margin-left: 10px; }
