In task 1, you saw how selecting elements that are inside another element is done using a descendant selector where the container and target are separated by a space.

So selecting "all <a> elements inside the unordered list with the ID gallery" is a similar task that you will also use a descendant selector for. The main difference from task 1 is that here the container will be specified using an ID instead of a tag name. And remember that when an ID is used as a specifier, it is preceded by a hash symbol ("#").

Then the target elements are the same as the first task, so the complete specifier would be :point_right: "#gallery a".
