Study Notes

Text Shadows

The text-shadow CSS property adds a shadow to text.
text-shadow has four values: horizontal offset, vertical offset, blur radius, and color.
A negative horizontal offset moves the shadow left, and a positive offset moves it right.
A negative vertical offset moves the shadow up, and a positive offset moves it down.
Blur radius determines the blur of the shadow. A value of 0px results in a sharp edge.
To add multiple shadows to the same text, use a comma-separated list of shadow values.

Box Shadow

The box-shadow property applies one or more shadows to an element.
box-shadow has five values: horizontal offset, vertical offset, blur radius, spread radius, and color.
The spread radius increases or decreases the size of the shadow. A positive value increases size; a negative value decreases size.

Backgrounds

The background-image property allows adding multiple background images to an element using a comma-separated list.
Each background image can be placed individually using the background-position property.
The background-origin property determines the box model area where the background image is placed: padding-box (default), border-box, or content-box.
The background-clip property specifies the painting area: border-box (default), padding-box, or content-box.

Background Images

The background-size property lets you control the size of background images.
Background images can be scaled using lengths, percentages, or the keywords contain (as large as possible but fitting within the content area) or cover (covering the entire content area).

Animation

CSS Animation enables you to animate HTML elements without JavaScript.
Animations work by defining keyframes with specific styles for the element at certain times.
To bind an animation to an element, use the animation property.
animation-duration sets the duration of the animation.
animation-iteration-count specifies the number of times the animation runs.
animation-delay sets a delay before the animation starts.
animation-direction controls the direction of the animation, which can be normal (default), reverse, alternate (forwards then backwards), or alternate-reverse (backwards then forwards).
animation-timing-function defines the speed curve of the animation, with options including ease (default), linear, ease-in, ease-out, and ease-in-out.

@keyframes Rule

The @keyframes rule defines the animation's keyframes.
It is followed by the name of the animation being defined.
Use selectors like from (0%) and to (100%) within the rule to specify styles for the animation's start and end points.
You can use additional selectors to define styles for specific percentages of the animation's duration.

Animation Example

The animation property can be used to animate an image, changing its position over time.
In one example, keyframes are defined to move an image in a rectangular pattern, moving the image to different positions at different percentages of the animation's duration.

@keyframes Rule and Selectors

The @keyframes rule allows you to create an animation by defining the styles the element will have at specific points in time.
Selectors, like from and to, are used within the @keyframes rule to target specific times in the animation. Each selector is followed by curly braces that contain the specific styles the element will have at that moment.
