Study Notes

CSS Selectors and Structure

Nested Selectors: Format involving multiple layers of selectors. Example: div p { font-family: Garamond; }
Hierarchy in HTML: Visualize HTML as a tree. Tags like <html> are parents, while <head> and <body> are children. Tags within these (e.g., <title>, ) are siblings and children at different levels.

CSS Basics

Universal Selector: The asterisk (*) formats all elements uniformly. Example: * { color: #3A5FCD; }
Classes: Denoted by a period (.) followed by the class name. Classes allow for consistent formatting across multiple elements. Example: .purple { color: purple; }
IDs: Identified by a hash (#) followed by the id name. Used for styling a single element distinctly. Example: #red { color: red; } IDs override both tag and class styles.

URL Components

Uniform Resource Locator (URL): A unique address for web pages. Example: https://blog.hubspot.com/marketing
Protocol (Scheme): Indicates the access method for the website; for example, using HTTPS for secure connections.
Subdomain: The initial part of a URL that specifies a particular segment of the site; for example, "blog" in the URL.
Second Level Domain: The main name of the website, such as "hubspot" within the URL.
Top-Level Domain (TLD): Indicates the nature of the entity that registered the site, such as .com, .org, etc.
Subdirectory (Path): Represents a specific section of the website, like "marketing" in the URL.

Networking and Accessibility

Servers: Networked computers providing requested data to users. Each server has a distinct address on the internet.
Internet Service Providers (ISP): Companies that grant access to the internet, facilitating online connectivity for users.
Browsers: Software applications (e.g., Chrome, Firefox, Safari) used by individuals to navigate the web.
Search Engines: Tools (e.g., Google, Bing) that locate documents based on user-specified keywords.

CSS Conflict Resolution

The Cascade: A system determining which CSS rules apply when conflicts arise based on importance, specificity, and rule order.
Important Modifier: A special rule that can override others when used with CSS declarations, activating with !important.
