For instance, the transition property can be utilized to animate adjustments in CSS properties over time. On this instance, the .field class units the width, peak, and preliminary background shade for the factor. The transition property is ready to background-color 0.5s ease to animate adjustments to the background shade property over half a second with an ease-in-out timing operate. The .field:hover class adjustments the background shade of the factor when the mouse pointer is over it, triggering the transition animation.

  transition: background-color 0.5s ease;
}

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

• Animations: CSS3 launched a variety of new properties and strategies for creating animations on net pages. On this instance, we’ve added an animation utilizing the animation property. We’ve outlined a @keyframes rule for the animation, which specifies that the field ought to rotate from 0 levels to 90 levels over a period of 0.5 seconds. When the field is hovered over, the spin animation is utilized to rotate the field. The animation-fill-mode property is ready to forwards to make sure that the ultimate state of the animation is retained after it finishes.

<div class="rotate"></div>

.rotate {
  width: 100px;
  peak: 100px;
  background-color: crimson;
  text-align: heart;
  show: flex;
  align-items: heart;
  justify-content: heart;
  shade: #fff;
  /* Add animation properties */
  animation-duration: 0.5s;
  animation-timing-function: ease;
  animation-fill-mode: forwards;
}

/* Outline the animation */
@keyframes spin {
  0% { remodel: rotate(0deg); }
  100% { remodel: rotate(90deg); }
}

• CSS Customized Properties: Also called CSS variables, customized properties had been launched in CSS3. They permit you to outline and use your personal customized properties in CSS, which can be utilized to retailer and reuse values all through your stylesheets.

On this instance, we outline a CSS variable known as –primary-color and provides it a worth of #007bff, which is a blue shade generally used as a main shade in lots of designs. We’ve used this variable to set the background-color property of a button factor, through the use of the var() operate and passing within the variable identify. This may use the worth of the variable because the background shade for the button.

:root {
  --primary-color: #007bff;

  shade: white;
  padding: 10px 20px;
}

• A number of Backgrounds: CSS3 lets you specify a number of background pictures for a component, with the power to manage its positioning and stacking order. The background consists of two pictures, crimson.png and blue.png, that are loaded utilizing the background-image property. The primary picture, crimson.png, is positioned on the proper backside nook of the factor, whereas the second picture, blue.png, is positioned on the left prime nook of the factor. The background-position property is used to manage the positioning of every picture. The background-repeat property is used to manage how the photographs repeat. The primary picture, crimson.png, is ready to not repeat (no-repeat), whereas the second picture, blue.png, is ready to repeat (repeat).

<div id="multibackground"></div>

#multibackground {
  background-image: url(crimson.png), url(blue.png);
