Writing accessible HTML code is essential for creating a website that can be used by everyone, regardless of their abilities. Accessible HTML code means that the content is structured in a way that makes it easy for people using assistive technologies to understand and navigate. In this blog, we’ll discuss some tips for writing accessible HTML code.
Use Semantic HTML
Semantic HTML is HTML that has meaning. It is essential for creating accessible web content. Semantic HTML elements, such as <header>, <nav>, <main>, <section>, <article>, <aside>, and <footer> should be used to describe the content on the page.
Use Proper Heading Structure
Heading structure is essential for creating a logical outline of the content on the page. Proper heading structure makes it easier for users of assistive technologies, such as screen readers, to understand the structure of the content on the page.
Use only one <h1> tag per page, and use subsequent <h2>, <h3>, <h4>, <h5>, and <h6> tags in order of hierarchy. This helps create a clear and logical outline of the content on the page.
Use Descriptive Link Text
Descriptive link text helps users of assistive technologies understand where a link will take them. Instead of using “click here” or “read more,” use descriptive text that tells the user what the link is for. For example, “Learn more about our services” is more descriptive than “click here.”
Use Alt Text for Images
Alt text is text that is used to describe an image. Alt text is essential for users of assistive technologies who cannot see the image. When writing alt text, be descriptive and concise. Use keywords that describe the image, but avoid using too many keywords.
Use Color Contrast
Color contrast is essential for users with low vision. Make sure that the text on your website has enough contrast with the background color to make it easy to read. Use a contrast checker to make sure that the contrast meets accessibility standards.
Use ARIA Attributes
ARIA (Accessible Rich Internet Applications) attributes provide additional information to assistive technologies about the functionality and structure of the content on the page. ARIA attributes should be used to provide additional context for interactive elements such as buttons, menus, and forms.
Use Tables Responsibly
Tables should be used for tabular data only. Avoid using tables for layout purposes. Use proper table markup, such as <thead>, <tbody>, and <tfoot> to make it easier for users of assistive technologies to understand the structure of the table.
Provide Captions and Transcripts for Media
Captions and transcripts are essential for users of assistive technologies who cannot hear audio or video content. Provide captions for videos and transcripts for audio content to make it accessible to everyone.
Conclusion: Writing accessible HTML code is essential for creating a website that can be used by everyone. Use semantic HTML, proper heading structure, descriptive link text, alt text for images, color contrast, ARIA attributes, responsible use of tables, and provide captions and transcripts for media to create an accessible website. By following these tips, you can create a website that is usable by everyone, regardless of their abilities.
