title: Proper CSS Code For Id Selector Not Type Or Class For A Certain Event
body: <p>I have two spans.  Each span has an id tag.  I don't want the spans to have a class tag.  I want to use css to underline the text in the span when the mouse hovers over it.  What is the proper code to do this on a single line in my css file?</p>
  
  <pre><code>&lt;span id=spanImagePreview1&gt;Text Here &lt;img src=url&gt;&lt;/span&gt;
  &lt;span id=spanImagePreview2&gt;Text Here &lt;img src=url&gt;&lt;/span&gt;
  </code></pre>
