td elements of the Rate column should contain a span element with the class of rate wrapping three empty span elements.
.rate elements placed inside .read rows should have an additional class with the value of either one, two, or three, depending on the personal rate. This value should come after rate.
No worries! It’s there in the User Stories number 14. It says:
You should use an attribute selector to target the span elements which are direct children of span elements with the class value starting with rate and set their border , border-radius , margin , height , width , and background-color
this one will not select anything, you do not have an element that has only class="one"
the attribure selector has some modifiers for how the value is matched, you may want to review them
