CSS Buttons vs Image Buttons
In the early days of the web, elaborate buttons were sliced as .png or .gif images and appended to the <button> HTML tag. This created massive load times, broke upon zooming, and made text unreadable for screen readers.
Generating Call to Action (CTA) buttons purely through CSS allows infinite scaling without pixelation, native dark-mode swapping, hardware-accelerated hover transitions, and impeccable accessibility standards instantly.
Essential Button Best Practices
- Padding Hierarchy: Always use more horizontal padding than vertical padding. A 1:2 ratio (e.g., 10px Top/Bottom, 20px Left/Right) aligns perfectly to human visual balance.
- Interactive States: A button must visibly react when hovered or focused. Dropping the background brightness by 10% or lifting the drop-shadow implies physical depth and interactivity.
- Readable Contrasts: If using a dark background color, ensure text is #FFFFFF (White) at a bold font weight. A primary CTA should be easily readable from a distance.
