https://www.linuxfoundation.org is mostly unusable with a touchpad on linux on chromium because they are using one of those smooth scrolling scripts.

Works for me in Firefox with a touchpad. Scroll does not seem hijacked.

also a wordpress theme ! (salient)

Equally with select dropdowns. Everyone and their mother reinvents them while covering maybe 50% of edge cases that a <select> tag does out of the box

I even have to do this to others as part of my latest project. I apologize, I have fought it and failed, and now I have no choice

We wouldn't have this problem if the <select> tag was easier to customize, and addressed the most common UI/UX issues that people (designers) have with it.

Anyway, given that this is not the case, the designers should have chosen a well-maintained library of UI components.

I agree, but given that it's such a reocurring problem, why is it not moving forward via the HTML5 living standard? We had this problem before with ES5 and while it was solved with jQuery, ES6 came along and solved a lot of these pain points. HTML doesn't seem to be moving in this direction (yet)

Is it that important? As a user I don't really care much how the select element looks. Standard one is totally fine for me. It allows to customize its size and colors and that is more than enough.

many wordpress themes do that, go figure why.
