Build a simple webpage using at least 5 different semantic HTML5 elements. Include a header, navigation, main content area with articles, and a footer.
+
+
+
+ Pro Tip: Always use the most specific semantic element available. This improves accessibility and helps search engines understand your content.

Lesson 2: Advanced CSS Layouts
+
Advanced CSS
+
+
+
+
Learning Objectives
+
+
Master CSS Flexbox for 1D layouts
+
Implement CSS Grid for 2D layouts
+
Create responsive designs with media queries
+
Use modern layout techniques effectively
+
+
+
+
+ CSS Flexbox is designed for one-dimensional layouts, while CSS Grid excels at two-dimensional layouts.
+
+
+
+
+
Flexbox Fundamentals
+
Flexbox makes it easy to design flexible responsive layout structures.
Create a webpage that uses Flexbox for a navigation bar and CSS Grid for the main content area. Make it responsive with media queries for mobile, tablet, and desktop views.
+
+
+
+ Pro Tip: Start with mobile styles first, then use min-width media queries to progressively enhance the layout for larger screens (mobile-first approach).
+
+
+
+
+
+
+
+
+
+
Lesson 3: Advanced CSS Effects
+
Advanced CSS 2
+
+
+
+
Learning Objectives
+
+
Create smooth CSS animations and transitions
+
Apply 2D and 3D transforms to elements
+
Use advanced visual effects like gradients and shadows
+
Implement modern CSS features like custom properties
+
+
+
+
+ CSS Transforms and Animations can create engaging user experiences without JavaScript.
+
+
+
CSS Transitions and Animations
+
Transitions allow property changes to occur smoothly over time, while animations provide more control over intermediate steps.
Build a card component that uses CSS transitions for hover effects and a simple animation when the page loads. Use CSS custom properties to make the design easily customizable.
+
+
+

+
Lesson 4: Web Accessibility Fundamentals
+
Web Accessibility
+
+
+
+
Learning Objectives
+
+
Understand the importance of web accessibility
+
Learn WCAG guidelines and principles
+
Implement proper semantic structure for screen readers
+
Create keyboard-navigable interfaces
+
+
+
+
+ Web Accessibility ensures that people with disabilities can perceive, understand, navigate, and interact with the web.
+
+
+
WCAG Principles (POUR)
+
The Web Content Accessibility Guidelines are built on four principles:
+
+
+
+
Perceivable
+
Information and UI components must be presentable to users in ways they can perceive.
+
+
Text alternatives for non-text content
+
Captions and other alternatives for multimedia
+
Content that can be presented in different ways
+
Easy-to-see and -hear content
+
+
+
+
+
Operable
+
UI components and navigation must be operable by all users.
+
+
Keyboard accessibility
+
Enough time to read and use content
+
Content that does not cause seizures
+
Easy navigation
+
+
+
+
+
+
+
Understandable
+
Information and operation of UI must be understandable.
+
+
Readable and predictable text
+
Input assistance for forms
+
Consistent navigation
+
+
+
+
+
Robust
+
Content must be robust enough to work with current and future user tools.
+
+
Compatible with assistive technologies
+
Valid and well-structured HTML
+
+
+
+
+
Accessible HTML Practices
+
Proper HTML structure is the foundation of accessibility:
+
+
+<!-- Use semantic elements -->
+<navaria-label="Main navigation">
+ <ul>
+ <li><ahref="#">Home</a></li>
+ <li><ahref="#">About</a></li>
+ </ul>
+</nav>
+<!-- Provide text alternatives -->
+<imgsrc="chart.jpg"alt="Bar chart showing sales growth from 2018 to 2022">
+<!-- Use proper form labels -->
+<labelfor="username">Username:</label>
+<inputtype="text"id="username"name="username">
+
+
+
+
+
+ Hands-On Activity
+
+
Audit and Improve Accessibility
+
Take an existing webpage (or create a simple one) and identify at least 5 accessibility issues. Then fix those issues using proper semantic HTML, ARIA attributes, and accessibility best practices.
+
+
+
+
+
+
+
Lesson 5: Accessibility Implementation
+
Web Accessibility
+
+
+
+
Learning Objectives
+
+
Use ARIA attributes to enhance accessibility
+
Implement keyboard navigation and focus management
+
Test websites for accessibility compliance
+
Apply accessibility techniques to complex components
+
+
+
+
+ ARIA (Accessible Rich Internet Applications) provides attributes to make web content more accessible when native HTML isn't sufficient.
+
+
+
ARIA Attributes and Roles
+
ARIA helps communicate information about elements to assistive technologies:
Several tools can help you test and improve accessibility:
+
+
+
Automated tools: axe, WAVE, Lighthouse
+
Screen readers: NVDA (Windows), VoiceOver (Mac)
+
Manual testing: Keyboard navigation, color contrast checkers
+
+
+
+
+
+ Hands-On Activity
+
+
Build an Accessible Component
+
Create an accessible modal dialog or tab component that includes proper ARIA attributes, keyboard navigation, and focus management. Test it with a screen reader and keyboard-only navigation.
+
+
+
+ Pro Tip: Remember the first rule of ARIA - don't use ARIA if you can use native HTML elements with the required semantics and behavior.
