quoting HTML attribute values

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.

Solution

  • 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"/>
