The style of email sent by woocommerce doesn't look good for me. Title are too big, border,...
While editing css of woocommerce shop part it's ok, thanks firebug to find the properties, when you want to change the email it's difficult: firebug doesn't locate the properties in your email account (yahoo,..).
I tried to to use the hook as mentioned here : http://www.grapekiwi.ca/how-to-edit-the-css-of-a-woocommerce-email-template/
but for doesn't do the job if i put for exenple h3 fontsize:2em;. THe properties is recognized but isn't first priority in css priority order: the h3 title stay at 30 px font-size.*
what is the good method?
