Several controls on the SIMCOAI website were a few pixels under the size we set ourselves for anything you tap with a thumb. Nothing was broken, but a near miss on a small button is a real irritation, and some of these were on the worst possible controls to have to aim at.
The cookie banner, which is the first thing anyone touches. The monthly, six-month and yearly toggle on the pricing page, where a mis-tap shows you the wrong price. The “compare all features” link on each plan card, which had no minimum size at all. And every tick box on the site, including the ones you have to tick to sign up, which were rendering two pixels smaller than intended.
Footer links were the odd one out: they were sized properly on a phone and then reverted to the compact desktop sizing on anything wider, so tablets got the tightest version of the lot. They now stay full size across the whole touch range.
All of this was found by measuring the rendered page rather than reading the stylesheet, which is why it had gone unnoticed — every one of these controls carried a size rule that another rule was quietly overriding.
