You develop an HTML application that contains a table that displays a list of products. The
table is defined with the following HTML markup:
You must style the table to look like the following image:
You need to implement the CSS selectors to select the rows that must have a blue
background.
Which CSS selector should you use?
A.
thead:only-child, tbody:after, table:before
B.
tr [line |-0, 1, 3]
C.
tr:first-of-type, tr:last-of-type
D.
tr:first-line, tr:last-child
Explanation:
Header (line 0), first line and third line.
Answer is C:

and Adjustable Race and Down Tube is the first and last element tr of tbody.

True, the answer B is not even usable, i can’t seem to understand how and why would people choose that answer. I have tested both and the only one that actually works is option C. I will put the code for those who won’t believe.
tr:first-of-type, tr:last-of-type
{
background-color: blue;
}
Product
Adjustable Race
Blade
Chainring
Down Tube
