Example
Use the alt attribute to specify an alternate text for each area in the image map:
<map name="planetmap"> <area shape="rect" coords="0,0,82,126" href="sun.htm" alt="Sun"> <area shape="circle" coords="90,58,3" href="mercur.htm" alt="Mercury"> <area shape="circle" coords="124,58,8" href="venus.htm" alt="Venus"> </map> Try it Yourself »Definition and Usage
The alt attribute specifies an alternate text for an area, if the image cannot be displayed.
The alt attribute provides alternative information for an image if a user for some reason cannot view it (because of slow connection, an error in the src attribute, or if the user uses a screen reader).
The alt attribute is required if the href attribute is present.
