Is there one that defaults to block
defaults to inlineinline-
button, textarea, input, and select default to inline-block.
In the event you would want to inline-block a div you'd give it a class name.
.inline-block {
display: inline-block
}
Then...
<div class="inline-block"></div>
CORRECTION
I was mistaken about img. It seems it defaults to inline and not inline-block
This isn't really a true answer to the question right now, but with enough support, it may someday be.
<seg> short for "segment". As in, segments of a line.
with the polyfill:
<style> seg { display: inline-block; } </style>
It really would be nice if there was an official one, but there is not, so here is the best (IMO) suggested name for such an element that I know of.
You can check my codepen with all HTML elements and their display property by default. Some tags are syntax-broken, but it does not matter for our purpose.
Currently, there are 5 elements with display: inline-block in FF :
<button><select><meter><progress><marquee>And additional 2 (including 5 above) in Chrome:
textareainputFrom what I can tell the <img> tag is the only inline-block by default. To be on the safe side I would recommend a class, you never know when changing all elements of a certain type will come back to bite you. Or, you could always make up your own tag and assign display:inline-block; to it. This way you aren't changing the default functionality of standard elements...
EDIT
It also appears that button, textarea, input, and select elements are also inline-block
Sources:
According to this img is inline-block http://dev.w3.org/html5/markup/img.html#img-display
And here claims that button, textarea, etc. are as well: http://www.w3.org/TR/CSS2/sample.html
EDIT #2
While the source above claims that img tags are inline-block it seems (thanks to Alohci) that they are just inline http://jsfiddle.net/AQ2yp/
The following were tested in Firefox:
button is inline-block: http://jsfiddle.net/GLS4P/
textarea is inline: http://jsfiddle.net/235vc/
input is inline: http://jsfiddle.net/RFKe8/
select is inline-block: http://jsfiddle.net/5B4Gs/
My solution to this is declaring what I call a slice.
CSS
sl {
display: inline-block;
}
Usage
<sl>inline block stuff</sl>
Here is a Fiddle that gets the default display value for a majority of HTML tags.

In chrome, the default inline-block elements are: "INPUT", "BUTTON", "TEXTAREA", "SELECT"
