2. Given the following CSS, what colour will the text be in the grandchild element?

    .child + .child .grandchild { color: orange; }
   

   Answers:

   • Red
   • Blue (correct answer)
   • Green
   • Orange

   The answer is blue, because it is the most specific selector.

3. Based on the following CSS, what will the height of the parent element be?

    #parent {
        width: 100px; 
        height: auto;
        display: relative;
    }
    #parent > #child-1 {
        width: 100px; 
        height: 100px;
        margin-bottom: 20px;
    }
    #parent > #child-2 {
        width: 100px; 
        height: 100px;
        margin-top: 20px;
    }
   

   Answers:

   • 220px (correct answer)
   • 240px
   • 200px
   • 210px

   The height will be 220px, because the margins will collapse.
