What tools does Apple use to build its landing pages?

Question

Layout

Hello.
I think many are familiar with the speed and smoothness of Apple's websites, and far from being on the most powerful devices.
So, maybe someone knows or at least suggests what technologies / tools Apple can use?

Answer 1

The same as everyone else. HTML/CSS/JS

Answer 2

Oyyy... We go to the first landing page from Apple , we observe a horizontal scroll, a hodgepodge of styles that are not even glued into one file and without trying to go somewhere further than the bootstrap approach, and in general there are a lot of problems and everything works extremely slowly and twitchy .
It is contraindicated for a technical specialist to focus on such a level, this is trash.
What tools are used? The brand and influence of the company, the trust of users, as well as sometimes interesting ideas for design and interaction.
And technically, darkness.
