CSS Flashcards
What is CSS?
Cascading Style Sheets is a coding language used for deciding the presentation of a document written in a markup language like html or xml. Helps keep the information content of a document separate from the details of how it should be displayed.
Why is CSS called “cascading”?
Refers to the inherent hierarchy between several different style sheets that can be active for a singe document at a time. The types are: Inline (body section), Internal/Embedded (the style for a single html), and External (a separate style sheet set once and on multiple web pages). Styles of higher precedence will override the rules of those with lower precedence. Specificity is used to decide which will apply to an element ie, Inline above Internal above External in the hierarchy.
What are some CSS selectors?
Simple: select elements based on name, id (#), or class (.). Includes universal (*)
Element Selectors: grouping/element (h1, h2, p, etc) selectors
Combinator: select based on specific relationships between elements
Pseudo-class: select based on certain state
Pseudo-elements: select and style a part of an element
Attribute: select based on an attribute or attribute value mentioned in square brackets ie [type=“text”]
What is the Bootstrap?

What is the Bootstrap grid?
