For some html attributes, I can use quotes around the values, or not:

For example, I can do

<table colspan='1'></table>

Or 

<table colspan=1></table>

Is there any difference between these two ways? Which is the more conventional way of doing things?

  • To play nice with your fellow programmers and reduce errors, always use some form of quotes to delineate the values you are setting for your attributes. – Anil Jan 03 '14 at 01:43

    And although this is a good question, it may be considered to be off-topic because it can lead to a subjective discussion, which is not something that SO is focused on. Cheers. – Anil Jan 03 '14 at 01:44

Wrap your values in quotes (single or double, just don't mix them):

  1. It's necessary for many values ( class="container modal warning" )
  2. It prevents confusing values with later attributes ( class="foo"id="bar" )
  3. People will like you, and treat you kindly.

During Tokenization, all three are considered (single, double, and none).
