` has no text, it's still treated as a box with content. Write a CSS rule that uses the `.canvas` class selector and set its `width` to 500 pixels. Here's a CSS rule that sets the width of the class `card` to 300 pixels: ```css .card { width: 300px; } ``` # --hints-- Your code should have a `.canvas` selector. ```js const hasCanvas = new __helpers.CSSHelp(document).getStyle('.canvas'); assert(hasCanvas) ``` You should set the `width` property to `500px`. ```js const hasWidth = new __helpers.CSSHelp(document).getCSSRules().some(x => x.style.width === '500px') assert(hasWidth); ``` Your `.canvas` element should have a `width` of `500px`. ```js const width = new __helpers.CSSHelp(document).getStyle('.canvas')?.getPropertyValue('width'); assert(width === '500px'); ``` # --seed-- ## --seed-contents-- ```css --fcc-editable-region-- --fcc-editable-region-- ``` ```html Rothko
