Answer 1

This has been mentioned in comments and is hard to find in one of the answers so:

If you are using display: flex for whatever reason, you can instead use:

div {
    display: inline-flex;
}

This is also widely supported across browsers.

Answer 2

div{
  width:auto;
  height:auto;
}

Answer 3

What works for me is:

display: table;

in the div. (Tested on Firefox and Google Chrome).

Just put a style into your CSS file

div { 
    width: fit-content;

Answer 6

My CSS3 flexbox solution in two flavors: The one on top behaves like a span and the one at the bottom behaves like a div, taking all the width with the help of a wrapper. Their classes are "top", "bottom" and "bottomwrapper" respectively.

body {
    font-family: sans-serif;
}
.top {
    display: -webkit-inline-flex;
    display: inline-flex;
}
.top, .bottom {
    background-color: #3F3;
    border: 2px solid #FA6;
}
/* bottomwrapper will take the rest of the width */
.bottomwrapper {
    display: -webkit-flex;
    display: flex;
}
table {
    border-collapse: collapse;
}
table, th, td {
    width: 280px;
    border: 1px solid #666;
}
th {
    background-color: #282;
    color: #FFF;
}
td {
    color: #444;
}
th, td {
    padding: 0 4px 0 4px;
}

Is this
<div class="top">
	<table>
        <tr>
            <th>OS</th>
            <th>Version</th> 
        </tr>
        <tr>
            <td>OpenBSD</td>
            <td>5.7</td> 
        </tr>
        <tr>
            <td>Windows</td>
            <td>Please upgrade to 10!</td> 
        </tr>
    </table>
</div>

Or may be...
<div class="bottomwrapper">
    <div class="bottom">
    	<table>
            <tr>
                <th>OS</th>
                <th>Version</th> 
            </tr>
            <tr>
                <td>OpenBSD</td>
                <td>5.7</td> 
            </tr>
            <tr>
                <td>Windows</td>
                <td>Please upgrade to 10!</td> 
            </tr>
        </table>
    </div>
</div>
this is what you are looking for.
