How to create a hover effect in a newsletter?

I'm creating a newsletter, and i want to have panels that change background-color on mouse over.

Seeing as the newsletter wont have a head, I am defining all styles inline. I'm pretty sure most popular mail clients will block JS. So I was wondering if I can define a hover effect in the style attribute. Or is there any 开发者_Python百科other solution to achieve this effect?

Peace

Have you checked these?

The latter article says this:

Hover effects are not supported in Outlook 2007/2010, Gmail, iOS or Android. You may still want to include the a:hover style for all supporting clients: Outlook 2000/2003, Hotmail, Apple Mail, and Yahoo! mail ...

Javascript is a no-go. There is really no solution to this, some will accept :hover, some not. From that first link you can see which will and which will not.

I you are certain your css will not be removed, you can use a hover and a background-color property

.panel:hover {
    background-color: #EFEFEF;
}

Also it does not seem possible to use a pseudo-selector in an inline style, so that might be a stopper:
