Consider using CSS custom properties (variables) for colors. This improves maintainability and makes it easier to manage the color scheme of your site, especially as it grows. You can define the colors in the :root selector and then reuse them throughout your stylesheet.

For example:

:root {
  --primary-color: #0d0a99;
  --text-color: #fff;
  --article-bg: #2c13a8;
  --aside-bg: #4d119b;
  --footer-bg: #3f12ba;
}

header {
  background: var(--primary-color);
  color: var(--text-color);
  padding: 20px;
  text-align: center;
}


nav ul {
list-style: none;
display: flex;
justify-content: center;
gap: 20px;
margin-top: 10px;
}

nav a {
color: #fff;
text-decoration: none;
}

main {
display: flex;
padding: 20px;
gap: 20px;
}

article {
flex: 3;
background: #2c13a8;
color: #fff;
padding: 20px;
border-radius: 8px;
}

aside {
flex: 1;
background: #4d119b;
color: #fff;
padding: 20px;
border-radius: 8px;
}

footer {
background: #3f12ba;
color: #fff;
text-align: center;
padding: 15px;
margin-top: 20px;
bottom: auto;
}

The bottom: auto; property on line 61 is redundant because auto is the default value for the bottom property. It can be removed to make the code cleaner without affecting the layout.

footer {
  background: #3f12ba;
  color: #fff;
  text-align: center;
  padding: 15px;
  margin-top: 20px;
}


@media (max-width: 768px) {
main {
flex-direction: column;
flex:1;
}

The flex: 1; property on line 67 has no effect. The flex property applies to flex items (direct children of a flex container), but the parent of main (the <body> element) is not a flex container. This line can be safely removed.

  main {
    flex-direction: column;
  }

Consider using CSS custom properties (variables) for colors. This makes your theme easier to manage and change, especially when you have different colors for different states or screen sizes as you do in the media queries.

For example:

:root {
  --box-bg-large: #3498db;
  --box-bg-medium: #e67e22;
  --box-bg-small: #2ecc71;
  --box-text-color: white;
}

.box {
  /* ... */
  background: var(--box-bg-large);
  color: var(--box-text-color);
  /* ... */
}

Then in your media queries, you would just update the background color property.

@keyframes bounce {
0%, 100% {
transform: translateY(0);
}
50% {
transform: translateY(-50px);
}
}
@media (max-width: 768px) {
.box {
width: 120px;
height: 120px;
font-size: 14px;
background: #e67e22;
}
}

@media (max-width: 480px) {
.box {
width: 90px;
height: 90px;
font-size: 12px;
background: #2ecc71;
}
}
</style>

For better maintainability, separation of concerns, and to leverage browser caching, it's a best practice to move CSS styles from the <style> tag into a separate .css file. You can then link to it using <link rel="stylesheet" href="animations.css"> in the <head>. This aligns with the "File Organization" best practice for CSS which was noted in the PR description.
