If the image failed to load the below output is shown which is more descriptive to the user.

We also recommend using a descriptive name for the images as well.

How To Make Links Accessible

Each and every link should be complete in itself and describe where it should go. Try to avoid Click Here, Read Blog, etc and if so then describe it before. For example, if we want to share the link to the current blog then the below code would be more useful and descriptive instead of read this blog or anything else.

        
        Read our blog on 
        <a href="https://lynxsia.com/blog/read/develop-web-accessible-websites-accessibility-guide-and-usage"
              title="Develop Web Accessible Websites - Accessibility Guide And Usage"/>
          Develop Web Accessible Websites - Accessibility Guide And Usage
         </a>
      
    

The above code generates the following output

We also recommend using the title attribute for the links as well.

How To Make Forms Accessible

When it comes to the forms, many users with disabilities can't use the mouse and/or keyboard. They depend on the screen readers to understand each input form is needed. To make the form accessible use <label> or aria-label to describe the information it needed. Use <fieldset> to group inputs and <legend> to label the group of inputs.

        
      
        <fieldset class="first-section">
          <legend>Contact Details</legend>
          <label for="name">Name</label>
          <input type="text" id="name" name="name" autofocus placeholder="John" autocomplete="on" required> <br><br>
          <label for="email">Email</label>
          <input type="email" id="email" placeholder="john@gmail.com">
        </fieldset>
      
    

How To Make Videos And Audio Accessible

All videos and audio must be properly described. Use captions, subtitles, and transcripts.

      
        <video id="video" controls preload="metadata">
          <source src="assets/video.mp4" type="video/mp4" />
          <track
            label="English"
            kind="subtitles"
            srclang="en"
            src="assets/vidoe-en.srt"
            default />
        </video>
      
    

How To Use Colors For Accessibility

For visual disabilities like color blindness, we need to take care of the contrast of the color so that content should be properly visible to users.

You can use any web tool for this purpose. For example, you can use a contrast ratio calculator or WCAG Color contrast checker

How To Make Animations And Transitions Accessible

For visual disabilities, we need to take care of the animations and transitions to be properly implemented so that they are visual to users. Use moderate speed and duration for the transitions and animations. Whenever possible use controls to handle transitions and animations.

Use Semantic HTML For Accessibility

Semantic HTML is very important for making websites accessible. Below are some key points for using HTML semantics for accessibility:

Use a proper and descriptive title for the web page.

Use the proper tag for the header, navigation, main body content, and footer.

Use proper heading tags for the heading instead of faking the heading with CSS.

Try to avoid div for the buttons to make interactive buttons, use button tags instead.

Use tabindex to interactive elements to make them keyboard-navigable. Use tabindex=0 and/or tabindex=-1. Don't use tabindex>1.

Use aria- attribute to give more information to assistive devices. For example, aria-hidden, aria-label, aria-controls, aria-describedby, etc.

Use role attribute to define the purpose of the elements to assistive devices. For example, role="button", role="grid", role="presentation", role="alert", etc.

Use keyboard navigation like enter, tab, and space to navigate the website and check accessibility.
