How come this code doesn't require display:block with <div style="

But what about for other browsers?

All browsers follow this behaviour:

Back to your question and there is indeed no need to add the display property to any html elements unless you are changing their default display properties. The user agent (UA / browser) sets all the display:values via its own stylesheet to the appropriate values for the elements concerned. Therefore there is no need for you to do this unless you need a different type of display for that element.
