SC 1.4.10 - What does "Reflow" mean?
Someone with reduced vision zooms to 400%. On a page that does not adapt, reading now means scrolling right, then back left, then right again, once per line. Everybody gives up after two paragraphs. WCAG says: content has to fit the screen without scrolling in two directions.
SC 1.4.4 - What does "Resize Text" mean?
Somebody finds your text too small and presses Ctrl and plus. The letters get bigger, and then it goes wrong: the last line of every card is gone, button labels sit on top of each other, and the menu will not open.
