Gmail：大于内嵌CSS样式中定义的大小的元素

Question

So I'm coding html of an newsletter and i'm using the inline styles because of restrictions, so my "table layout" is broken because have elements with size bigger than the defined. I realize that an element with 170px of height defined, and inside them have an tag with 170px of height defined, so why using inspect i can see that this have 172px, i think Gmail is ignoring something.

I make a gif to show this in inspector: http://i.imgur.com/VqNsxrY.gif

My JSfiddle with my html: http://jsfiddle.net/wtkd/ygfn6qka/ (the boxes with images of mario shows where layout breaks) If you don't want to see in JSfiddle:

  <table width="700" align="center" style="background-image: url('http://www.image.test.com/images/bg.jpg'); background-color: #ededed; background-position: center top; background-repeat: no-repeat; margin:0;padding:0;padding: 0; width: 700px; margin: 0 auto;">

Someone can help about this?

Answer 1

You need to put display:block; inline on all your img tags.

Answer 2

It's something related to the way <a> are displayed. Changing their display property to block (individually, or globally with a style, and I'm curious to know why you are not allowed to use it) did the trick: running demo

<style>
    a {
        display : block;        
    }
</style>
