Study Notes

CSS Colors

Colors in CSS are specified using predefined color names (e.g., Gray, Tomato), RGB, HEX, HSL, RGBA, or HSLA values.
In HTML, colors are often specified using a color name within the style attribute, such as style="background-color:Gray;".
background-color is a predefined CSS attribute used to change the background color. Any predefined HTML element (e.g., <h1>, , <div>, <body>) can have its background color changed.

Sample Program

The provided example code demonstrates how to use different predefined colors to style HTML elements.
The examples show how to use HTML elements like <h1> to change the backgrounds of those elements using CSS.
The example code demonstrates applying different colors with both pre-defined names and a range of color values

Color Values

RGB (Red, Green, Blue): Each parameter (red, green, blue) defines the color intensity from 0 to 255. Examples of RGB values are rgb(255, 0, 0) (red), and rgb(0, 0, 0) (black). rgb(255, 255, 255) (white) is included in the examples.
HEX: Represents colors using hexadecimal values (00-FF) for red, green, and blue. Example: #ff0000 (red)
HSL (Hue, Saturation, Lightness): Defines colors using hue (degrees on the color wheel), saturation (percentage of color strength), and lightness (percentage of brightness).

RGBA Value

RGBA (Red, Green, Blue, Alpha) is an extension of RGB, adding an alpha channel for opacity. The alpha value is a number between 0.0 (fully transparent) and 1.0 (fully opaque).

HSLA Value

HSLA (Hue, Saturation, Lightness, Alpha) is an extension of HSL, adding an alpha channel for opacity. The alpha value is a number between 0.0 (fully transparent) and 1.0 (fully opaque).

CSS Backgrounds

CSS background properties control background effects. Common properties include:
- background-color
- background-image
- background-repeat
Background images can be positioned using background-position.
Backgrounds can be fixed using background-attachment.

CSS Border Properties

CSS border properties control the style, width, and color of elements' borders. Examples of border styles include dotted, dashed, solid, double, groove, ridge, inset, outset, none and hidden.
border-width specifies the width of the borders, can be defined using values like 5px, thin, medium, or thick. border-color specifies the color of the borders. border-radius creates rounded borders.

CSS Margins

CSS margins create space around elements, outside the defined borders.
Properties like margin-top, margin-right, margin-bottom, and margin-left allow individual margin control for each side.
A shorthand property margin can be used to set all margins at once (e.g., margin: 25px 50px 75px 100px; represents top, right, bottom, left margins respectively).

CSS Padding

Padding adds space around the content of an element, inside its border.
Properties like padding-top, padding-right, padding-bottom, and padding-left are used.
A shorthand property padding can be used to set all padding values.

CSS Display

The display property controls element layout.
Common values include block and inline.
Block-level elements start on a new line and occupy the full available width within their container.
Inline elements take up only the necessary width and do not start on a new line within the container. For example,  is an inline element.

CSS Float

The float property positions elements (e.g., images) horizontally relative to surrounding elements.
Common values for float include left, right, none, and inherit.

Setting li a:hover can visually change the look on a link when the mouse moves over it.

CSS Dropdowns

Using CSS, dropdown lists can be created that appear when the mouse hovers over an element. Code examples demonstrate the use of position, display, background-color, etc., to create dropdown effects.

CSS Transitions

CSS transitions create smooth changes in property values over a specified duration.
The transition effect requires the property name and duration, as in, width 2s

CSS Animations

CSS animations gradually change the styles of HTML elements and
These animations can be created by using keyframes.
animation-duration defines length of time the animation will take to complete.
