Colors & Text

Every color on a webpage is described to CSS in one of a few ways. A named color, like red or dodgerblue, is the easiest to read but limited to a fixed list. A hex code, like #1E2A5A, is six characters representing red, green, and blue amounts in a compact format this is what designers usually hand you. rgb(30, 42, 90) writes the exact same color as three plain numbers from 0-255. The color property sets TEXT color specifically not backgrounds, not borders, just text. Fonts work similarly: font-family names the typeface, but because not every visitor's device has every font installed, you always list a fallback, like font-family: 'Poppins', sans-serif if 'Poppins' isn't available, the browser falls back to any generic sans-serif font instead of showing nothing. font-size controls how big text is, and font-weight controls how bold it looks, usually as a number like 400 (normal) or 700 (bold).
