I have created an email template that is tested to work properly on desktop clients like gmail/yahoo/outlook and also tested correct responsive behavior on mobile gmail app. I am using Android/Galaxy S4.
The responsive styles are not effective on yahoo mobile app. Infact, it is not reading the CSS rules from 'style'. Though, desktop chrome set to mobile views (using Inspect -> toggle device toolbar) and logging in to yahoo mail shows the email reading the responsive styles.
Question: Does yahoo mobile app not support responsiveness? Or, does it particularly need additional hacks?
Update: I tried moving the CSS styles from head to body. It then reads the styles. But having styles in the body may not to be a good idea, gmail mobile app now ignores it.
Here is the email code that I am using:
<!DOCTYPE html>
<html lang="en">
