By establishing a clear visual hierarchy, you can guide users’ attention and make it easier for them to navigate and understand your website or application.

Providing Alternative Text for Images and Media

When it comes to making your website accessible, providing alternative text for images and media is crucial. Alternative text, also known as alt text, is a brief description that is read aloud by screen readers for visually impaired users. It allows them to understand the content and context of the image or media file. Alt text should be concise and descriptive, providing enough information for users to comprehend the purpose of the visual element. It is important to use keywords that accurately describe the image or media, while avoiding excessive details or unnecessary information. By including alt text, you ensure that all users, regardless of their visual abilities, can fully engage with your website’s content.
