Working with HTML emails can be tough with all the various email clients out there. Just ask Jim Basio, who wrote a great post on our blog with some really useful resources. Recently I was working on an HTML email that had a lot of images, and for some reason Hotmail displayed the images with weird spacing. Let's pretend the picture below is actually three separate images in an email viewed in Hotmail:
As you can see, there is a gap between the images. We can fix this with one simple addition to the image style with CSS:
<img src="image.jpg" alt="Viget Logo" style="display: block;" />
And that's it. Just put "display: block" on any image in your HTML. I put it inline because there are still issues with email clients reading the <style> element (for example, Hotmail). Your images should now be in the right place:
The good news is that it doesn't affect the way images are displayed in other email clients. If you have other useful tips for HTML emails let us know!
UPDATE: This problem only seems to happens in Hotmail when using Firefox (although I feel like I saw it in IE before...). Another good tip, from a reader named Jurre-Jan Smit, was that you can just put the code in the <style> element in the <head> (for Live Hotmail) and <body> (for old school Hotmail) so that you don't need to put it inside every image. I just tend to use inline styles in emails because they're more specific. I've found Campaign Monitor's guide on CSS support in emails very useful for answering compatibility questions.
