Study Notes
HTML Semantic Elements
- HTML5 introduces semantic elements to provide meaning to structure of a web page
- Replaces generic div elements with descriptive elements
- Examples:
- header: defines the header section of a document or section
- nav: defines a section of navigation links
- main: defines the main content section of a document
- section: defines a self-contained section of related content
- article: defines an independent piece of content
- aside: defines a piece of content that is related to the surrounding content
- footer: defines the footer section of a document or section
CSS Grid
- A two-dimensional grid system for layout
- Grid container: the element that contains the grid
- Grid items: the elements that are direct children of the grid container
- Grid tracks: the horizontal or vertical lines that make up the grid
- Grid cells: the spaces between the grid tracks
- Properties:
-
grid-template-columnsandgrid-template-rows: define the number and size of grid tracks -
grid-columnandgrid-row: define the grid cells that an item occupies -
justify-itemsandalign-items: define the alignment of grid items within cells
-
Responsive Design
- The practice of designing websites that adapt to different screen sizes and devices
- Techniques:
- Media queries: apply different styles based on device characteristics (e.g. screen size, orientation)
- Flexible grids and images: use relative units (e.g. percentages, ems) instead of fixed units (e.g. pixels)
- Mobile-first design: design for small screens first, then add styles for larger screens
- Breakpoints: define points at which the layout changes in response to screen size
Web Accessibility
- The practice of designing websites that are usable by everyone, including people with disabilities
- Guidelines:
- Perceivable: provide alternative text for images, provide closed captions for audio and video
- Operable: make navigation intuitive and consistent, provide sufficient time for users to read and use content
- Understandable: make text readable and understandable, help users avoid and correct mistakes
- Robust: maximize compatibility with assistive technologies and future technologies
- Tools:
- WAVE Web Accessibility Evaluation Tool: evaluates a website's accessibility
- Lighthouse: audits a website's accessibility, performance, and best practices
Flexbox
- A one-dimensional layout mode for laying out items in a row or column
- Container properties:
-
display: flexordisplay: inline-flex: enable flexbox layout -
flex-direction: define the direction of the flexbox layout (row or column)
-
- Item properties:
-
flex-growandflex-shrink: define how items grow or shrink in relation to each other -
flex-basis: define the initial main size of an item -
justify-contentandalign-items: define the alignment of items within the container
