CSS Hover

In CSS, the :hover pseudo-class is used to apply styles to an element when a user hovers over it with their mouse pointer. It allows you to create interactive and engaging effects for elements that change their appearance or behavior when interacted with.

The :hover pseudo-class is typically used in combination with other CSS selectors to target specific elements.

The syntax for using the :hover pseudo-class is as follows:

selector:hover {
  /* Styles to apply when the element is hovered */
}

• selector: Represents the CSS class, ID, or element selector of the element you want to style when it is hovered.
• :hover: The pseudo-class that applies the styles when the element is hovered.

Example:

button:hover {
  background-color: #ff0000;
  color: #ffffff;
}

In this example, when a user hovers over a <button> element, it will change the background color to red (#ff0000) and the text color to white (#ffffff).

You can apply various styles to the element when it is hovered, such as changing the background color, text color, font size, adding transitions, showing additional information, and more.

a:hover {
  text-decoration: underline;
}

img:hover {
  transform: scale(1.1);
}

.dropdown:hover .submenu {
  display: block;
}

In the above examples, hovering over a link (<a> element) will underline it, hovering over an image (<img> element) will scale it up by 10%, and hovering over an element with the class .dropdown will display a submenu with the class .submenu.

Using the :hover pseudo-class can enhance the user experience by providing visual feedback when interacting with elements on your web page. However, be mindful of using it in a way that doesn’t cause unexpected or jarring changes, especially when applying hover effects to elements that trigger important actions, such as buttons and links.
