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.
