Pixel Art Basics for Front-End Developers
You already know grids and hex codes. Pixel art is just those, drawn one square at a time — no art degree needed.
You already know the tools
Pixel art is a grid where each cell is one color. If you've written a CSS grid and picked a hex code, you've done the boring half already. The fun half is choosing where to put the colors.
Start tiny — twelve by twelve pixels is plenty for a first sprite. Big sprites are just more cells, not a different skill.
Draw with a letter map
Instead of hand-placing every pixel, write your sprite as an array of strings — one character per pixel, a dot for empty space. Each letter maps to a color. Read the array in a loop and create one element per non-dot pixel.
This makes the sprite editable as text. Change a letter, redraw. You can see the shape forming in the source code itself.
const MAP = [
"..cc..",
".ckkc.",
"ckggkc",
".kllk.",
];
// c = cork, k = ink, g = glass, l = liquid
Keep it crisp
Tiny pixels get blurry by default because the browser tries to smooth them. One line of CSS — image-rendering: pixelated — turns that smoothing off and keeps every square sharp.
Outline first, fill second
Sketch the outline color first, like inking a drawing. Then fill the interior colors. Doing it in passes keeps you from losing track of which pixel is border and which is body — the same way a real illustrator works.
