> As a frontend developer, building responsive and accessible web applications is an essential part of your job. These applications not only need to look great on different devices and screen sizes, but also need to be easy to use for everyone, including users with disabilities.

_In this post we are going to go about how to make your application or website more responsive and accessible for users. Below are some of the best practices for building responsive and accessible web applications._

### 1. Design for Different Screen Sizes
With the increasing use of mobile devices, it's important to design web applications that look good on different screen sizes. This means using responsive design techniques, such as media queries and flexible grids, to adjust the layout and presentation of the application based on the size of the device's screen.

To get started with responsive design, you can use CSS frameworks, such as Bootstrap or Foundation, which provide a set of pre-designed components that you can easily customize and use in your own projects. Additionally, you can use tools such as Flexbox or Grid to create flexible and responsive layouts, and adjust the font size, line height, and other typographic elements based on the screen size.

### 2. Optimize for Performance
Performance is key to providing a great user experience, especially on mobile devices. There are several ways to optimize the performance of your web applications, including:

- Minifying and compressing your CSS, JavaScript, and HTML files.

- Using image compression tools to reduce the size of images used in your application.

- Lazy loading images, videos, and other media that are not immediately visible on the page.

- Implementing efficient algorithms and data structures to reduce the amount of processing time required to render the page.

- Code splitting to reduce loading time by downloading only the required files at a given time.

### 3. Make it Accessible
Accessibility is the practice of making web applications usable by people with disabilities, such as visual or motor impairments. To make your web applications accessible, you can:

- Use semantic HTML elements, such as header, nav, abbr, figure, figcaption, ul and main, to provide context and structure to the page.

- Provide alternative text for images and other non-text content. This enables screen readers to pickup on what the element video or image is, for visually impaired users.

- Use ARIA attributes to provide additional information about the elements on the page.

- Make sure that your web applications are keyboard-navigable, so that users can use the keyboard to interact with the page.

### Conclusion
Building responsive and accessible web applications is an important part of frontend development. By designing for different screen sizes, optimizing for performance, and making it accessible, you can provide a great user experience for all users, regardless of the device they are using. These are just a few of the best practices to keep in mind when building your next web application. Good luck!
