Base Apparel with CSS Grid

I built the solution mobile first using CSS Grid with

• 1 column and 3 rows for mobile
• 2 columns and 2 rows for desktop, with the image spanning the 2 rows in the 2nd column

Is this a good way to approach the grid?

Accessibility I tried linking the error text with the input by adding aria-describedy="subscribeErrorText" to the input field when the error is shown. Is this legitimate? Are there other/better ways of doing it?

Any other feedback on the layout and the code is appreciated :) Have fun
