A small suggestion, if I may - browsing your landing page, I found it would occasionally jump each time your ‘typing text’ changed towards the top of the page.

A small suggestion, if I may - browsing your landing page, I found it would occasionally jump each time your ‘typing text’ changed towards the top of the page. You might want to set a static height on that div, or maybe just have a permanent zero-width space at the start of the div to give it a height when there aren’t any visible characters. Or I suppose you could just tweak the JS so that it only runs when it is visible, otherwise it’s paused maybe?
