- Flexible Images: Images resize based on screen size.
Here’s a basic example of a media query:
@media (max-width: 600px) {
body {
background-color: lightblue;
}
}
This code changes the background color to light blue on small screens.
Using responsive design techniques is vital. Websites must adapt to varying screen sizes. This improves user experience and keeps visitors engaged.
Adding Interactivity With Javascript
Creating a website with HTML, CSS, and JavaScript is exciting. HTML structures the content, CSS styles it, and JavaScript makes it interactive. Adding interactivity with JavaScript transforms a simple web page into a dynamic experience. Users engage more when they can click, type, and see immediate responses. Let’s explore how JavaScript enhances user interaction through DOM manipulation and event handling.
Dom Manipulation
DOM stands for Document Object Model. It represents the structure of a web page. JavaScript can change the content, style, and structure of a web page in real time. This makes your website feel alive.
Here are some common DOM manipulation methods:
- getElementById: Selects an element by its ID.
- getElementsByClassName: Selects elements by their class.
- querySelector: Selects the first matching element.
With these methods, you can:
- Change text inside elements.
- Add or remove elements.
- Change styles to make the page colorful.
Example of changing text:
document.getElementById('myElement').innerHTML = 'Hello, World!';
Here’s a simple table showing some DOM manipulation methods:
Method | Description |
---|---|
innerHTML | Sets or gets the HTML content. |
style | Changes CSS styles directly. |
appendChild | Adds a new child element. |
Through DOM manipulation, you can create a unique and engaging experience for users. This capability keeps them coming back for more.
Event Handling
Event handling is another exciting feature of JavaScript. It allows the website to respond to user actions. Actions can include clicks, keyboard presses, or mouse movements. By using event listeners, you can trigger functions based on these actions.
Common events include:
- click: Fires when an element is clicked.
- mouseover: Fires when a mouse pointer moves over an element.
- keypress: Fires when a key is pressed.
To use event handling, you can follow this simple format:
element.addEventListener('event', function() {
// Your code here
});
For example, to show an alert when a button is clicked:
document.getElementById('myButton').addEventListener('click', function() {
alert('Button clicked!');
});
Event handling makes your website interactive and fun. Users feel in control when they see immediate results from their actions. This connection is key to a successful web experience.
