text link convert into button

[sagarweb]

I want that this text of Change the Brand which you are seeing should turn into a button, for this I have also written a code, which you can see in the image below, if I run this code then it becomes a button but its alignment changes on mobile, it looks correct on desktop but its alignment changes on mobile, I want it to become a proper button and do its work properly.

Maybe you could consider moving that text button below the product options? This adjustment should make the mobile display fine
