First you have to set just the color and background of all the <li> from <ul> elements So your code should look like this in the css file:

ul li {color: white; background-color: black;}

Then you have to set the third child background to the value 'FF6347':

ul li:nth-child(3){background-color: #FF6347;}

Then set the first 4 elements to font-weight: bold

ul li:nth-child(-n+4){font-weight: bold;}

And finally change the last 3 elements font size:

ul li:nth-child(n+3){font-size: 30px;}

Thankyou so why do we use ul li:nth-child(n+3){font-size: 30px;} and not li:nth-lastchild ?

I prefer to use it that way but will work perfectly well this way too "ul li:nth-last-child(-n+3)"

Keep coding
