Do you know that currently there is one special Html Codes that can work with Blogger to draw attention to your reader. You can do it under the Edit Html mode.
It is the Blink function. Just wrap your text inside the blink tag and make your text Blink in Blogger. This special effect works for Firefox browser only.

Blink tag allows your text content to blink and can be easily done with this simple command:
<*blink>Write anything here for the text you want it to blink<*/blink>

For bold or italic blinking text, you can use b or i to wrap inside and also set color for the text:
<*blink><*b>Write anything here for the text you want it to blink<*/b><*/blink>

Note: remove the * for the code to work as below:

Write anything here for the text you want it to blink
