question about parents

ok so i understand these concepts in regards to elements like li, ul, h1 etc... but would an element like a button or input form still be considered an element? i have found myself going back to review because later on in this course when we set event targets i found myself quite lost in figuring out how to do something like "let button=ul.parentNode" if someone can help explain the basic parent children relationship a bit better would help me out a ton! thanks

Anything with a tag name is an HTML element, including buttons and inputs.

But the example of "let button=ul.parentNode" is not likely. Assuming the variable "button" is meant to represent a button element, a button would not be the parent of a ul. In HTML, a "parent" is the same thing as a "container". So this example would suggest that a ul was inside a button.

A more typical example might be something like this:

<ul>
  <li><button>Start</button></li>
  <li><button>Stop</button></li>
</ul>

In this example, the ul is the parent of two li's, which are each the parent of a button. So you might see code with "let ul=li.parentNode" or "let li=button.parentNode".

thanks so much. I remember learning all this stuff way back and now i am finding myself reviewing basic HTML again. the reviewing and going back seems to be a pretty standard thing with coding! thanks again
