table { caption-side: top; }
caption-side defines the placement of a table’s <caption> element. The caption can be positioned at the top, bottom, or logical sides of the table, depending on text direction and writing mode.
writing-mode: vertical-rl, block-start places the caption on the right side of the table.
caption-side is supported in all modern browsers, including Chrome, Firefox, Safari, and Edge. Logical values are widely supported as well, though some very old browsers may only recognize top and bottom.
caption-side is not an animatable property. Changes are applied instantly without transition effects.
