**Course Title:** Modern CSS: Responsive Design and Advanced Techniques **Section Title:** Transitions, Animations, and Transforms **Topic:** Implement CSS animations and transitions to enhance user experience on a webpage. **Objective:** In this lab topic, you will learn how to implement CSS animations and transitions to enhance the user experience on a webpage. You will understand the properties and techniques used to create smooth and engaging animations, and how to apply them to real-world projects. **Pre-Requisites:** - Understanding of CSS syntax and selectors - Familiarity with CSS transitions and animations concepts - Basic understanding of HTML and CSS **Key Concepts:** - CSS Animations: The `@keyframes` rule, animation properties (animation-name, animation-duration, animation-delay, etc.) - CSS Transitions: The `transition` property, transition timing functions, and transition delays - Transforming elements: The `transform` property, rotate, scale, skew, and translate **Lab Instructions:** For this lab, you will be working on a sample webpage that includes various interactive elements. Your task is to enhance the user experience by implementing CSS animations and transitions. **Step 1: Setting up the project** - Download the sample webpage files from [this GitHub repository](https://github.com/modern-css-lab/webpage-template). - Open the files in your preferred code editor. - Familiarize yourself with the HTML structure and CSS styles. **Step 2: Implementing CSS Animations** - Open the `styles.css` file and navigate to the `.animated-element` class. - Define a keyframe animation using the `@keyframes` rule. For example: ```css @keyframes fadeIn { 0% { opacity: 0; } 100% { opacity: 1; } } ``` - Apply the animation to the `.animated-element` class using the `animation` property. For example: ```css .animated-element { animation: fadeIn 3s infinite; /* other styles */ } ``` - Test the animation by refreshing the webpage. **Step 3: Implementing CSS Transitions** - Open the `styles.css` file and navigate to the `.interactive-button` class. - Define a transition effect using the `transition` property. For example: ```css .interactive-button { transition: background-color 0.5s ease-in-out; /* other styles */ } ``` - Test the transition by hovering over the button and checking the background color change. **Step 4: Transforming Elements** - Open the `styles.css` file and navigate to the `.grid-item` class. - Define a transform effect using the `transform` property. For example: ```css .grid-item { transform: scale(1.1); /* other styles */ } ``` - Test the transform by checking the size and position of the grid items. **Practical Takeaways:** - CSS animations and transitions can greatly enhance the user experience on a webpage. - Keyframe animations can be used to create complex animations using the `@keyframes` rule. - Transitions can be used to create smooth effects using the `transition` property. - Transforming elements can be used to change the size, position, and orientation of elements using the `transform` property. **Challenge Exercises:** - Implement a CSS animation to rotate an element on hover. - Create a CSS transition effect to change the background color of a button on click. - Transform an element to create a 3D effect using the `perspective` property. **Additional Resources:** - [MDN Web Docs: CSS Animations](https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Animations) - [MDN Web Docs: CSS Transitions](https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Transitions) - [CSS-Tricks: Transforming Elements](https://css-tricks.com/snippets/css/transform-elements/) **Leave a comment or ask for help if you have any questions or need further assistance.**
