CSS CSS Basics (2014) Understanding Values and Units Styling the Intro Paragraph

.intro { font-size: 16px; font-size: 1.25rem; } What am I doing wrong? I'm supposed to find rems for 16px.

.intro {
  font-size: 16px; 
  font-size: 1.25rem; 

converting 16px to 20px using rems

/* Complete the challenge by writing CSS below */

  /*  Parent Font Size = 16px  */

  font-size:1.25em; /* 20px / 16px = 1.25em */

They are giving your the parent font size. You don't need the root.

Remember that rem stands for Relative Em. This is different than em because a rem unit is changed depending on the size of its parent element.
