You’ve combined the selectors with nothing between them, .cap.sleeve. That would select anything that had both of those classes - that isn’t what you want.

Selector Example Example description
.class .intro Selects all elements with class=“intro”
.class1.class2 .name1.name2 Selects all elements with both name1 and name2 set within its class attribute
.class1 .class2 .name1 .name2 Selects all elements with name2 that is a descendant of an element with name1
#id #firstname Selects the element with id=“firstname”
* * Selects all elements
element p Selects all


element.class p.intro Selects all

elements with class=“intro”

element,element div, p Selects all
elements and all


element element div p Selects all

elements inside

element>element div > p Selects all

elements where the parent is a


Can you see which one of those most closely matches our needs? Hint: It’s row number is more than 7 and less than 9. :wink:
