DOM-free text measurement. 15KB. By Cheng Lou.
Type anything. Resize the container horizontally. The font size adjusts in real-time via binary search against Pretext's layout engine — no DOM reflow, no flicker. Pure math.
Drag the slider. Pretext predicts the exact height and line count at every width before the browser renders a single pixel. The prediction matches reality.
Text rendered directly on canvas using Pretext's measurements. Move your cursor over the text — characters near the pointer scatter and repel, then snap back. This is impossible with DOM text.
