CSS Animations and Transitions Quiz

CSS Animations and Transitions

Animations

• Define animations using the @keyframes rule, which specifies the animation's style and duration
• Use the animation property to apply the animation to an element
• Properties:
  • animation-name: specifies the name of the animation
  • animation-duration: specifies the duration of the animation
  • animation-delay: specifies the delay before the animation starts
  • animation-iteration-count: specifies the number of times the animation should repeat
  • animation-direction: specifies the direction of the animation (normal, reverse, alternate)
• Example: @keyframes spin { 0% { transform: rotate(0deg); } 100% { transform: rotate(360deg); } }

Transitions

• Define transitions using the transition property
• Properties:
  • transition-property: specifies the property to transition (e.g. width, height, background-color)
  • transition-duration: specifies the duration of the transition
  • transition-delay: specifies the delay before the transition starts
  • transition-timing-function: specifies the timing function of the transition (e.g. linear, ease-in-out)
• Example: transition: width 2s, height 2s;

HTML5 Semantic Elements

Introduction

• HTML5 introduced new semantic elements to improve the structure and meaning of web pages
• These elements provide better search engine optimization (SEO) and accessibility

Common Semantic Elements

• header: defines the header section of a document or section
• nav: defines a section of navigation links
• main: defines the main content section of a document
• section: defines a self-contained section of related content
• article: defines an independent piece of content, such as a blog post or news article
• aside: defines a piece of content that is related to the main content, but not essential
• footer: defines the footer section of a document or section
• figure and figcaption: define a figure and its caption

Other Semantic Elements

• mark: defines marked or highlighted text
• time: defines a specific date and time
• progress: defines a progress bar
• meter: defines a scalar value within a known range

Note: These elements can be used to improve the structure and accessibility of web pages, but they do not affect the layout or visual appearance of the page.
