Function on this example

Hi there,

I still don't get the function here...

IF divList.style.display === "none"

what is NONE?

And,

IF divList.style.display = 'block'

Thank you

Hi Silvia,

display is a CSS property that can take the values of "none" and "block". Block is the default value and the HTML element will display normally. If display is set to none the element will not be displayed on the page.

For example, if you put the following code in your css file (or style tag) your <h1> tag will simply not be rendered on the page.

h1 {
  display:none 
}
