title: Is it possible to shrink the font size in case of an overflow?
body: <p>The <code>overflow</code> attribute allows to hide the content not fitting in the bounding box or it is possible to show scroll bars to scroll the content through a smaller view port.</p>
  
  <p>But is it also possible to shrink the font size of the child to prevent an overflow?</p>
  
  <p>In general it would be no option to shrink the text size, but I use <a href="http://www.fileformat.info/info/unicode/block/miscellaneous_symbols_and_pictographs/utf8test.htm" rel="noreferrer">Unicode pictographs</a> with font size of 300%. And in this case it would be acceptable to shrink the font size down to 100%.</p>
  
  <p>Is it possible to detect an overflow?</p>
