quoting HTML attribute values

Question

Hi

I know the spec allows both ' and " as delimiters for attribute values, and I also know it's a good practice to always quote.

However I consider " being the cleaner way, maybe it's just me having grown up with C and C++' syntax.

What is the cleanest way of quoting attribute values and why? Please no subjective answers.

Answer 1

Either is good, as long as you use it. " is more popular.

Answer 2

Both are fine, but Double quotes are better (IMHO) as you reduce the risk of dynamic values causing errors. e.g.

<input value='${lastName}'/>

<input value='O'Graddy'/>
                ^^^^^^^

vs.

<input value="${lastName}"/>

<input value="O'Graddy"/>

Sorry, there are only subjective answers to that question.
