Specify the desired value for the unit size. Accepted values include pixels, percentages and aspect ratio.
If necessary, you retain the ability to manually adjust these values within the embed code form.
If you opt to configure the unit's size to adhere to a specific aspect ratio, such as 16:9 or 4:3, the unit will adapt its dimensions to match those of the parent element in which it's rendered while preserving the designated aspect ratio. This approach is particularly useful for ensuring responsive design.
