Programming in HTML5 with JavaScript and CSS3.
Web Applications certification qualifies you for a position as a web developer or web administrator.
Implement and manipulate document structures and objects
- Create the document structure
- Structure the UI by using semantic markup, including for search engines and screen readers (Section, Article, Nav, Header, Footer, and Aside); create a layout container in HTML
- Write code that interacts with UI controls
- Programmatically add and modify HTML elements; implement media controls; implement HTML5 canvas and SVG graphics
- Apply styling to HTML elements programmatically
- Change the location of an element; apply a transform; show and hide elements
- Implement HTML5 APIs
- Implement storage APIs, AppCache API, and Geolocation API
- Establish the scope of objects and variables
- Define the lifetime of variables; keep objects out of the global namespace; use the “this” keyword to reference an object that fired an event; scope variables locally and globally
- Create and implement objects and methods
- Implement native objects; create custom objects and custom properties for native objects using prototypes and functions; inherit from an object; implement native methods and create custom methods
Implement program flow
- Implement program flow
- Iterate across collections and array items; manage program decisions by using switch statements, if/then, and operators; evaluate expressions
- Raise and handle an event
- Handle common events exposed by DOM (OnBlur, OnFocus, OnClick); declare and handle bubbled events; handle an event by using an anonymous function
- Implement exception handling
- Set and respond to error codes; throw an exception; request for null checks; implement try-catch-finally blocks
- Implement a callback
- Receive messages from the HTML5 WebSocket API; use jQuery to make an AJAX call; wire up an event; implement a callback by using anonymous functions; handle the “this” pointer
- Create a web worker process
- Start and stop a web worker; pass data to a web worker; configure timeouts and intervals on the web worker; register an event listener for the web worker; limitations of a web worker
Access and Secure Data
- Validate user input by using HTML5 elements
- Choose the appropriate controls based on requirements; implement HTML input types and content attributes (for example, required) to collect user input
- Validate user input by using JavaScript
- Evaluate a regular expression to validate the input format; validate that you are getting the right kind of data type by using built-in functions; prevent code injection
- Consume data
- Consume JSON and XML data; retrieve data by using web services; load data or get data from other sources by using XMLHTTPRequest
- Serialize, deserialize, and transmit data
- Binary data; text data (JSON, XML); implement the jQuery serialize method; Form.Submit; parse data; send data by using XMLHTTPRequest; sanitize input by using URI/form encoding
Use CSS in applications
- Style HTML text properties
- Apply styles to text appearance (color, bold, italics); apply styles to text font (WOFF and @font-face, size); apply styles to text alignment, spacing, and indentation; apply styles to text hyphenation; apply styles for a text drop shadow
- Style HTML box properties
- Apply styles to alter appearance attributes (size, border and rounding border corners, outline, padding, margin); apply styles to alter graphic effects (transparency, opacity, background image, gradients, shadow, clipping); apply styles to establish and change an element’s position (static, relative, absolute, fixed)
- Create a flexible content layout
- Implement a layout using a flexible box model; implement a layout using multi-column; implement a layout using position floating and exclusions; implement a layout using grid alignment; implement a layout using regions, grouping, and nesting
- Create an animated and adaptive UI
- Animate objects by applying CSS transitions; apply 3-D and 2-D transformations; adjust UI based on media queries (device adaptations for output formats, displays, and representations); hide or disable controls
- Find elements by using CSS selectors and jQuery
- Choose the correct selector to reference an element; define element, style, and attribute selectors; find elements by using pseudo-elements and pseudo-classes (for example, :before, :first-line, :first-letter, :target, :lang, :checked, :first-child)
- Structure a CSS file by using CSS selectors
- Reference elements correctly; implement inheritance; override inheritance by using !important; style an element based on pseudo-elements and pseudo-classes (for example, :before, :first-line, :first-letter, :target, :lang, :checked, :first-child)
