I want to have the underlined and blinking at the same time. Is there any way to achieve this modifying only the CSS style of
Easiest is to set border-bottom to your h2:
border-bottom
h2 { border-bottom:1px solid black; text-decoration:blink; }
Please note that blink isn't supported in IE, Chrome and Safari
You need to space separate them:
text-decoration: underline overline line-through;
