Text is the element you will use most. It is plain text (no HTML), styled entirely through the sidebar, and it has a couple of superpowers other elements lack.
Select a block and press T, or use the "Add Text" button. Double-click any text on the canvas (or press F2) to edit it in place.
With a text element selected, the "Text / Font" group in the right sidebar covers all typography:
By default a text element auto-sizes: the box is exactly as big as the text, and grows as you type. That is the right behavior for most labels and titles, but two situations need an explicit size, set in the "Layout & Size" group:
In "Relative (%)" mode, width is a percentage of the block, so text sized this way adapts when its block is placed at a different size on another pane. In "Fixed (px)" mode it stays at its pixel width regardless. Height almost never needs to be set - leave it on auto and it follows the content.
Text can have a different width and height on each pane where its block appears (custom code is the only other element that can). A title can span the full hero block on pane one and tuck into a narrow column on pane two, reflowing as part of the transition. All other elements share one size across panes and resize per pane through Scale instead.
Note that font size is shared across panes. To make text visually smaller on one pane, change its Scale in "Position & Transform" on that pane - scale is per-pane, and it animates smoothly during navigation.
Beyond the general entrance animations, text has its own set, applied in the "Animation" group:
The four per-character animations (typewriter, letter-fade, letter-scale, letter-blur) default to a slow, cinematic pace (1.5-2s). For snappy headlines, raise the animation speed well past 1 - 2.5x to 4x lands a title in under a second.
A text element is also a box. The "Fill & Border" group gives it a background color, border, and corner radius, and "Layout & Size" adds horizontal and vertical padding. Fill plus padding plus a large radius is the recipe for buttons, badges, and caption pills - no extra shape element needed.
One caveat: the Shadow effect is a box shadow on that rectangle, not a per-letter text shadow. For legibility over busy images, prefer a filled pill or a scrim shape behind the text.
