We send out a New Order Confirmation and the font size of the credit card information and Processed amount are too big, I like to change the font size. I have tried to do this in the Magento Admin panel but the change does not take effect.

The order confirmation show "Payment Method" and then below that shows the: Credit Card type: Credit card Number: (Last four digits) Processed Amount:

I would suggest to change it from transaction email section.

If you have customised default new order email template then you can simply go to System > Transactional Email then open the new order template then find the Payment Method section and add inline css.

For ex:

 ///head part
 <th align="left" width="325" bgcolor="#EAEAEA" style="font-size:13px; padding:5px 9px 6px 9px; line-height:1em;">Payment Method:</th>

 //// body part
 <td valign="top" style="font-size:12px; padding:7px 9px 9px 9px; border-left:1px solid #EAEAEA; border-bottom:1px solid #EAEAEA; border-right:1px solid #EAEAEA;">{{var payment_html}}</td>

If you have't customised the template then you can create one and add inline css. Learn how to add transactional email here.

OR you can simply add inline css in default template in app/locale/[your_language]/template/email/sales/order_new.html

Hope this helps.

  • I see that in the coding they are using the Inline css, I not sure how this works? {{template config_path="design/email/header"}} {{inlinecss file="email-inline.css"}} <table cellpadding="0" cellspacing="0" border="0"> Commented Dec 1, 2016 at 21:37
  • For header, you will need to change in app/locale/[your_language]/template/email/html/header.html Commented Dec 4, 2016 at 22:10
