The original question was “How to write hover color using inline CSS?”
But this is not possible with inline css but possible with inline javascript.
Demo: Hover the link below
Here is the code:
<a href="http://shaplakanon.com/wpsupport"
onMouseOver="this.style.color='green'"
onMouseOut="this.style.color='black'" >WordPress Maintenance Service</a>Explanation:
onMouseOver executes when you hover the link.
onMouseOut executes when you hover the link and remove cursor.
