Oops, looks like your font size is 16px instead of 16px


What do I do here?

<h1 style="font-family: Arial"><h1 style="font-size: 16px"><li>This item is big Arial.</h1></li>


style is an attribute we can add to many html elements, including list opening tags:

<li style="">

if you want multiply style values, you can just separate them by a semi-colon:

<li style="property: value;property: value;">

i recommend to remove your heading tags from your list, and add the style attribute to the right opening tag

for next time, use one of the two following options to make your code/indent is visible:

select your code and press ctrl + shift + c (or cmd + shift + c if you use a mac)

if this instructions are unclear, you can also insert 3 backticks before and after your code, like so:


the backtick is located above the tab key on your keyboard


You haven't started your ordered or unordered list using the ol or ul tag.May be thats why its returning an error.
