What is an HTMLSelectElement and an HTMLInputElement?

I'm attempting to learn VBA by rea开发者_如何学运维ding through someone's code and understanding what happens every step of the way. However, I'm confused at to what these two elements are:

What is a HTMLSelectElement?

What is a HTMLInputElement?

See the W3C HTML Specs:

HTMLSelectElement

HTMLInputElement

I assume they correspond to select and input HTML tags. A select tag is also called a drop-down list, and input tags can be used for multiple things (checkbox, radio button, text, password).
