Fragments are like those extra HTML elements we used but they come without all the drawbacks. Some months ago, React version 16.2 was released, it shipped with this new feature that helped to address this accessibility problem called fragments. As regards to accessibility, which will be explained later in this post, it is very difficult for screen readers to interpret non-semantic code and so this method, albeit simple is not advisable. In instances like rendering lists items where we use extra elements like div tags are used, it can easily lead to non-semantic HTML. This is the most popularly used method but it is also the most inaccessible solution. Any other tag will deviate from HTML semantics. You can see that after a ul tag, the next logical HTML tag to expect is either li or a closing ul tag. Remove all the code inside the div of the return statement. Open the project in VS Code, navigate to the src folder and open the app.js file. Navigate into the fragments folder and run the new app in development environment like this: npm start Unzip the folder and then install all the dependencies with this command: npm install OR You can just download an already created new React project here. Navigate to a folder of your choice and create a new React application called fragments with the CRA boilerplate by running this command below npx create-react-app fragments Install create-react-app globally too with this command below npm install -g create-react-app Install React globally by running the command below in a terminal: npm install -g react We will go through the process of setting up the development environment and installing all the required dependencies for create-react-app to work.

This article is suited for all levels of expertise using React JS, this includes beginners. For these technologies to work, developers have to always think and build accessible applications. Accessibility support is necessary to allow assistive technology like screen readers to interpret web pages and applications. Everyone here includes people with auditory, cognitive, neurological, physical, speech and visual disabilities. Achieving accessibility in ReactĪccessibility on the web is the design of pages, tools and technologies that can be used by everyone. You will be taken through a series of illustrations and also code samples to let you properly understand the usefulness and how React fragments came about. In this article, you will be shown a new feature called fragments in React that lets you do so in a very accessible memory efficient way. This can be achieved in a number of ways that will be discussed in this post, most of which however can lead to HTML that is not accessible or even to writing non-semantic code. Sometimes while using React, you want to display or return multiple HTML elements in a component. You will learn why it is important as regards accessibility and how to use it.
