HTML=CSS-JAVASCRIPT

Hello there👋! Congratulations on completing this challenge!

The code looks fine with the exception of the following:

1.The font family "Josefin Sans" was not specified correctly in the CSS. To fix this, add the fallback font-family "sans-serif" after "Josefin Sans".

2.The CSS selector for the button hover effect was incorrect. To fix this, change "button:hover" to ".btn:hover".

Here is the corrected code:

* {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
}

html {
  font-size: 62.5%;
}
