Advanced CSS

Now that you understand the basics of CSS, let's explore more advanced techniques, including layout, positioning, and transitions.

Box Model

The box model is essential to understand how elements are laid out. It consists of margins, borders, padding, and the actual content.

.element {
  margin: 10px;
  padding: 20px;
  border: 1px solid black;
}
    

Positioning

Elements can be positioned using the position property.

• Static: Default position of elements.
• Relative: Positioned relative to its normal position.
• Absolute: Positioned relative to its nearest positioned ancestor.
• Fixed: Stays in the same place even when scrolling.

Flexbox

Flexbox is a powerful layout model that helps align and distribute space among items in a container.

.container {
  display: flex;
  justify-content: center;
  align-items: center;
}
    

Transitions

CSS transitions allow you to change property values smoothly (over a given duration).

.button {
  transition: background-color 0.5s;
}

.button:hover {
  background-color: blue;
}
