alt-attribute

What is the purpose of the alt attribute on images?

Answer

The alt attribute provides alternative information for an image if a user cannot view it. The alt attribute should be used to describe any images except those which only serve a decorative purpose, in which case it should be left empty.

Good to hear

• Decorative images should have an empty alt attribute.

• Web crawlers use alt tags to understand image content, so they are considered important for Search Engine Optimization (SEO).

• Put the . at the end of alt tag to improve accessibility.
