How is attr() better than using a css variable?

• Inviz 1y ago
  hmm... where to start? - Variables cascade and cause restyle of whole sub-tree. - Attributes often are already on the html element, e.g. title, aria, data attributes, so dont need inline styles - Not mixing data with presentation Just to name a few

    But if you‘re defining the style within the data (the width within the HTML as data attribute), aren‘t you actually mixing presentation with data?

  They do different things, they aren't really in competition with each other.

  attr() lets you read values from your html in css. CSS variables do not.

    You can set css variables in the style attribute.

      Not if you use a strict Content Security Policy without unsafe-inline
