What does the animation-fill-mode: forwards; property-value combination do?

  • Applies styles defined in the keyframes to the element before the animation starts
  • Holds the final keyframe styles after the animation finishes
  • Keeps the animation running indefinitely
  • Stops the animation as soon as it completes
The animation-fill-mode: forwards; property-value combination holds the final keyframe styles after the animation finishes. This means that after the animation completes, the element retains the styles from the final keyframe. This can be useful for maintaining a particular state after the animation finishes.

How does an element with position: sticky; behave when scrolling past its container?

  • It becomes transparent.
  • It disappears from the layout.
  • It remains fixed in its original position.

What is the result when an element does not have a specific style defined but its parent does?

  • The browser applies default styles to the element.
  • The element inherits styles from a global stylesheet.
  • The element inherits the styles from its parent.
  • The element remains unstyled.
When an element does not have a specific style defined but its parent does, it will inherit the styles from its parent. This inheritance is a fundamental concept in CSS and helps maintain consistency in the appearance of web pages.

How does Autoprefixing aid in ensuring cross-browser compatibility?

  • Autoprefixing adds vendor-specific prefixes to CSS properties, ensuring compatibility with various browsers.
  • Autoprefixing automatically generates alternate versions of your styles for different browsers.
  • Autoprefixing replaces outdated CSS properties with modern equivalents.
  • It converts JavaScript code to CSS for browsers that do not support modern JavaScript.
Autoprefixing is the process of adding vendor-specific prefixes to CSS properties to ensure cross-browser compatibility. It automatically generates CSS rules with the necessary prefixes, like -webkit-, -moz-, or -ms-, making sure that your styles are correctly interpreted by different browsers. This helps avoid the need for writing separate CSS rules for each browser.

  • lower, upper

You're optimizing a website for better scroll performance. Which CSS property would you use to hint to the browser about an element that will change frequently?

  • position: fixed;
  • transform: translate3d(0,0,0);
  • will-change
  • z-index
To optimize scroll performance, you can use the will-change property to hint to the browser that an element will change frequently. This allows the browser to prepare for the changes and allocate resources accordingly, improving scrolling performance. While using transform: translate3d(0,0,0); can also trigger hardware acceleration, it may not be as specific or efficient as will-change. z-index and position: fixed; are unrelated to hinting to the browser about frequent changes in an element.
