Can someone explain to me what is this for if selecting 4 x unknown in all questions leads to this?<p>&lt;div style=&quot;margin-left:auto;margin-right:auto;&quot;&gt; (DIV)
&lt;div style=&quot;text-align:center;&quot;&gt;Text Content&lt;&#x2F;div&gt; (TEXT)<p>If this is supposed to work, then by reduction, having more information about height&#x2F;width is unnecessary for both browser and CSS programmer. Why not just always use those two forms?
