First you learn the rules. Then you learn when to break the rules.
I believe in Cascading Style Sheets. I cringe when I see the typical use of inline styles. Despite that, I’ve trained myself to use them [sparingly] on Take the First Step.
Because I don’t get to set the style sheet of the browser based feed aggregators out there. And a section or a wide image can force the browser to use a horizontal scroll bar for an entire set of posts.
Please do users of browser based aggregators a favor. Add an inline style of style=”overflow:auto; width:100%” to any wide post elements. It will add a horizontal scroll bar to just that element. Your readers will thank you.
