Why is this important?
Older HTML tags and attributes that have been superseded by other more functional or flexible alternatives (whether in HTML or CSS ). Such superseded are declared as deprecated in HTML by the W3C - the consortium that sets the HTML standards. Browsers should continue to support deprecated tags and attributes, but eventually these tags are likely to become obsolete and so future support cannot be guaranteed.
How can I resolve this issue?
Replace the deprecated tag with a valid HTML tag.
