How can I improve text readability with CSS for users with visual impairments?

Answer

Improving text readability for users with visual impairments involves using CSS to enhance contrast, size, and spacing. These adjustments help ensure that text is more accessible and easier to read.

Example Concept: To improve text readability, use high contrast between text and background colors, increase font size, and adjust line height and letter spacing. For instance, a dark text on a light background or vice versa can enhance visibility. Additionally, using a minimum font size of 16px and a line height of 1.5 can make text easier to read. Consider using relative units like em or rem for scalability, and ensure sufficient spacing between letters and lines.

Additional Comment:

Ensure color contrast meets WCAG guidelines, typically a ratio of at least 4.5:1 for normal text.
Use semantic HTML elements to improve screen reader accessibility.
Consider user preferences for font size and contrast by allowing them to adjust settings if possible.
Test your design with accessibility tools to ensure compliance and usability.
