Challenge your understanding of Angular Material and UI components with these practical questions on theming, layout, design patterns, and component usage. This quiz helps strengthen your grasp of building consistent, interactive, and accessible interfaces using popular UI component libraries in Angular projects.
Which of the following is the correct approach to applying a custom color palette theme to Angular Material components in a project?
Explanation: To customize themes, you must define a color palette using SCSS and include it through Angular Material's built-in theming functions, ensuring the entire application adopts the new look. Assigning a palette via an HTML attribute only allows choosing default theme colors, not custom palettes. Installing a package per color is unnecessary and inefficient. Modifying TypeScript files directly is not only unsupported but also risks breaking future updates or compatibility.
When designing a responsive navigation layout using UI components, which Angular Material component is most appropriate for a side navigation that can collapse on smaller screens?
Explanation: The Sidenav component is tailored for creating side navigation drawers, with built-in support for responsive and collapsible behavior. Dialog is intended for modals and popups, not persistent navigation. Expansion Panel is used for collapsible content sections but isn't for navigation structure. Table is meant for displaying data in a tabular format and not for layouts or navigational elements.
Which 'appearance' value enables an outline style with a floating label for an Angular Material form field component?
Explanation: The 'outline' appearance gives form fields a distinct outlined border and a floating label, making them visually prominent. The 'filled' option fills the input area with color but uses a different border style. 'Legacy' uses an older appearance without modern updates and styling. 'Standard' provides a subtle underline rather than a full outline, so it's not suitable when a strong border is needed.
If you want to enable sorting for columns in an Angular Material data table, which additional module or directive should be included alongside the table?
Explanation: MatSort is the directive required to enable sorting on table columns, allowing users to organize data by clicking on column headers. MatPaginator is used for pagination, breaking the table into pages rather than sorting it. MatStepper helps create step-based processes or forms but has no effect on tables. MatMenu is used for menus and context options, not sorting functionalities.
Which practice is essential to improve accessibility when creating custom Angular UI components that represent interactive elements?
Explanation: For accessibility, it's vital to include ARIA roles and ensure keyboard interaction so all users, including those using assistive technologies, can operate components. Making visual mimics of native elements does not guarantee accessibility if underlying semantics are missing. Prioritizing only responsive design overlooks other accessibility needs. Using low contrast colors can actually hinder accessibility, making content harder to read, especially for those with visual impairments.
