How would i make my buttons neon? 

example https://codepen.io/elwinvdhazel/pen/VzwzWK

however i would like the neon to me pink and matching. 

Also how do I add typing-text CSS animation  to my Neon Headings. 

I'd love my neon-text headings to type-affect on scroll ?

Also how do I add drop-down text element to my headings on scroll 

I sort of achieved it on my reviews page but the font is wrong.

I'd also like to add the text animation - drop-down text to some of my headings with neon font how would I achieve this? 

Also any feed back on the website would be greatly appreciated.  Just working on style accepts at the moment the website copy is just  text place holders. Thank you.
