How can I make my image map accessible?

Accessibility is an important aspect of web design. You can make your image map accessible by adding alternative text to each area of your map.

You can also use ARIA roles and properties to improve the accessibility of your image map.

Can I use CSS to style my image map?

Yes, you can use CSS to style your image map. You can apply styles to the img and area elements of your map, and use pseudo-classes like :hover and :active to add interactivity. However, keep in mind that CSS support for image maps is limited, and some styles may not work as expected.

How can I optimize my image map for SEO?

Optimizing your image map for SEO can help improve its visibility on search engines.
