You've probably noticed that the font size, color, and overall layout of tweets is different from other social networks in the Feeds module and in a Feeds element. This is because of Twitter's design specifications. These guidelines also stipulate that we cannot show the numbers of likes and comments within the posts, and we cannot play videos inline.
One of Twitter's other requirements is that the text must always be shown with the image. As a result, we cannot display an image from a Twitter post by itself and must include a blue overlay when the text appears on top of the image. These differences are more noticeable in the image-only feed styles, such as the slideshow option for a Feeds element.
Because we must adhere to these guidelines to continue including Twitter in our service, it's not possible to tweak these designs within Feeds. We appreciate your understanding!
