project 8 or so...

👾Hello again Santiago Morales, Congratulations on completing this challenge!

Here's some tips to fix your background image:

To add the two wave svg background images in the (top/bottom),, the best way is by using background-image to manage it since adding them to the body you make sure it will be under everything, to manage different images inside a single css property as background-image you use the comma inside each properties declare the single modification for each circle separated. See the code below to see your solution with those backgrounds applied:

body {
    background-image: url(./images/bg-pattern-top-desktop.svg), url(./images/bg-pattern-bottom-desktop.svg);
    background-position: left -185px top -236px, right 10px bottom -300px;
    background-repeat: no-repeat;
    background-attachment: fixed;
    background-size: contain, contain;
    font-family: "League Spartan", sans-serif;
    height: calc(100vh - 0.1px);
    display: flex;
    justify-content: center;
    align-items: center;
}

✌️ I hope this helps you and happy coding!
