One thing I noticed about this is that the line break in the text is in kind of an odd place. It would look better to balance the two lines, breaking somewhat later. I get that the people who created the site in-universe are supposed to be somewhat web-design challenged, so that’s probably enough to explain it. They tried just having the text be an unbroken <p> container, and the line was too long, so they broke it in the first place that occurred to them. You can see where they dropped the <br> tag into the HTML:
<p class=”style1”>We’re sorry. Due to reasons <br> beyond our control, we are no longer able to offer this product.</p>
And I guess it doesn’t really matter. But my meta-show headcanon is that whoever coded it that way did it on purpose, and not just to look web-design challenged, but as a wink to the Tumblr-mediated fandom, for whom it works just fine without the second line.
