title: How to underline every line of text, to the end of a block
body: <p>So, here's my question, I'm doing a newsletter for a customer, which will look like a postalcard.</p>
  
  <p>I want my layout to look like writing on lines</p>
  
  <p>Can anyone help me achieve what I'm trying to do?
  Putting my text in TD tags doesn't work since I don't know the length of each sentences.</p>
  
  <p>Let me know if you need more info!</p>
  
  <p>Thanks :)</p>
