Study Notes

HTML Input Elements

Text Area: Defined by the <textarea> tag. Has rows and cols attributes for height and width.
Radio Buttons: The <input type="radio"> tag. Uses a name attribute to group related options and a value attribute for each option. Only one radio button in a group can be selected at a time. Crucial for constraining user selection.
Checkboxes: The <input type="checkbox"> tag. Uses name and value attributes. Can be selected/unselected, or have a default selected state controlled by the checked attribute, meaning it will be pre-checked. Only transmits a value if checked.
Password Input: The <input type="password"> tag. Masks user input for security. Uses attributes:
- maxlength: Maximum character limit.
- minlength: Minimum character limit.
- pattern: Regular expression to validate input (e.g., [A-Za-z0-9]{8,}) for at least 8 alphanumeric chars.
- required: The user must enter a value

HTML Select Menus

Select Menu: The <select> tag. Creates a drop-down list. multiple attribute allows selecting multiple options simultaneously. size attribute determines the height of the list box; has no effect without multiple unless value is 1. required attribute forces a selection. disabled attribute prevents user interaction and submission.
Select Options: The <option> tags within the <select> tag define each option in the list. Each <option> has a value attribute for what data is sent to the server

CSS (Cascading Style Sheets)

CSS Selectors: Target HTML elements by name, class, or ID (e.g., p, .center, #demo), enabling style application.
CSS Rulesets: Declare style rules (e.g., color: red;) for the selected HTML elements, separating the property (color) and the value (red).
CSS Properties: Style characteristics like color, font-size, text-align.
- Property values are placed after the colon (:).
- Multiple declarations in a selector are separated by a semicolon (;).
Selectors & Declarations: Combine multiple selectors and declarations in a CSS rule set.
- selector { property: value; property2 : value2; }.
Inline Styles: Apply styles directly to individual HTML elements using the style attribute of the HTML element.
Internal Styles: Define styles within an HTML document, applying those styles only to that document.
External Styles: Create separate .css files to define styles, linking them to HTML documents for reusability and maintainability.

HTML and CSS Box Model

Box Model: A fundamental concept in CSS and HTML, describing how elements are laid out on a web page, conceptually wrapping the element, in layers of content, padding, border and margin (e.g., a border around text, space around a button)
Content: The actual text or elements displayed inside an HTML element.
Padding: The space between the content and the border.
Border: The visible line around an element.
Margin: The space outside the border of an element
