Learn CSS Foundations Projects - CSS Foundations Exercise C

Tell us what’s happening:

i have a issue with my validator and i dont know what i didnt do right:

  • You should set the font-size for both elements to 28px using a grouping selector.
  • You should have a grouping selector for styles that both elements share.
  • You should have a list of fonts containing Helvetica and Times New Roman with sans-serif as a fallback.

Your code so far

<!-- file: index.html -->
<!DOCTYPE html>
<html lang="en">

    <title>Grouping Selectors</title>
    <link rel="stylesheet" href="styles.css">


    <button class="one">Click Me!</button>
    <button class="two">No, Click Me!</button>

/* file: styles.css */
.one {
    background-color: black;
    color: white;

.two {
    background-color: yellow;


button {
    font-size: 28px;
    font-family: Helvetica, Times New Roman, sans-serif;
