Study Notes
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 animationanimation-duration
: specifies the duration of the animationanimation-delay
: specifies the delay before the animation startsanimation-iteration-count
: specifies the number of times the animation should repeatanimation-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 transitiontransition-delay
: specifies the delay before the transition startstransition-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 sectionnav
: defines a section of navigation linksmain
: defines the main content section of a documentsection
: defines a self-contained section of related contentarticle
: defines an independent piece of content, such as a blog post or news articleaside
: defines a piece of content that is related to the main content, but not essentialfooter
: defines the footer section of a document or sectionfigure
andfigcaption
: define a figure and its caption
Other Semantic Elements
mark
: defines marked or highlighted texttime
: defines a specific date and timeprogress
: defines a progress barmeter
: 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.
CSS Animations and Transitions
Animations
- Define animations using the
@keyframes
rule, specifying the animation's style and duration - Apply animations to elements using the
animation
property - Animation properties:
animation-name
: specifies the animation's nameanimation-duration
: specifies the animation's durationanimation-delay
: specifies the delay before the animation startsanimation-iteration-count
: specifies the number of times the animation should repeatanimation-direction
: specifies the animation's direction (normal, reverse, alternate)
- Example animation:
@keyframes spin { 0% { transform: rotate(0deg); } 100% { transform: rotate(360deg); } }
Transitions
- Define transitions using the
transition
property - Transition properties:
transition-property
: specifies the property to transition (e.g. width, height, background-color)transition-duration
: specifies the transition's durationtransition-delay
: specifies the delay before the transition startstransition-timing-function
: specifies the timing function of the transition (e.g. linear, ease-in-out)
- Example transition:
transition: width 2s, height 2s;
