Three Modern CSS Features

Bookmarked Modern CSS in a Nutshell (Cloud Four)

A friend recently shared his frustration with CSS development. I responded to him with a high-level overview of the current state of CSS. If you’re feeling a bit out of touch with modern CSS development, I hope this helps. You’d be surprised how much you can do with vanilla CSS nowadays!

This is me — feeling totally out of the loop on CSS these days after knowing a fair bit ten years ago.

He recommends learning:

  • CSS variables
  • Flexbox
  • CSS grid

Web Design Tools


Accessible Palette – Create color systems with consistent lightness and contrast

Accessible Color Generator – Show me the closest variations of COLOR that contrast against BACKGROUND COLOR enough to meet ACCESSIBILITY GUIDELINES

Contrast Grid – Test many foreground and background color combos for compliance with WCAG 2.0 minimum contrast.

Coolers – color palette generator

Optimal Overlay Finder – For Readable Text on a Background Image

Vivid Gradient Generator – we interpolate the gradient in a hue-based color system, such as HCL, HSB, or HCL (not RGB) 🤓. This avoids the line of gray that goes through the center of every color space.

Gradient Easing Generator – Create and preview your own easing gradients in CSS.


The Good Line-Height – the good line-height calculates the exact number so it always fits the baseline grid!


Clippy – The clip-path property allows you to make complex shapes in CSS by clipping an element to a basic shape (circle, ellipse, polygon, or inset), or to an SVG source.
