title: Using Database Primary Key in HTML ID
body: <p>Just wanted to ask.</p>
  
  <p>I have site where each user is linked to an ID in the Database and this Primary Key is included in many tables. The fastest way for me to pull a users information is to have this ID.</p>
  
  <p>Would it be considered bad practice to put this ID in website HTML code? eg id="theIDnumber"</p>
  
  <p>Otherwise i can just use the username and then reference this in the Database for this ID - which is fine but using the ID would be faster I believe.</p>
  
  <p>thoughts?</p>
