BaselineLab
ChatGPT pluginExplore HTML and CSS
HTML and CSS playground with twenty labs: Grid, Flexbox, Columns, Grid Lanes, border, border-radius, color-mix, box-shadow, datalist, details, Popover, text-box, text-wrap, filter, backdrop-filter, background-image, light-dark(), contrast-color(), transform 2D and dialog. Search by name or purpose, filter by category, adjust native controls, inspect reusable code and continue with the same settings on BaselineLab. Local changes are shared with the model only when requested. Features show current-environment support notices and identify fallbacks; rendering does not establish support in other browsers. Black/white color selection does not certify accessibility.
