 * Hello,
    I’ve recently set-up my WordPress site using a child theme based on the
   Twenty Thirteen theme.
 * I’m now trying to correct any errors using the ‘Markup Validation Service Website’.
 * It’s reporting both ‘Duplicate attribute id.’ and ‘Duplicate attribute class.’
   errors.
    I’m assuming these are related to having set-up a child theme – maybe
   they are duplicate from the original theme?
 * I’m really struggling to get rid of these errors. I’m fairly new to WordPress,
   so would really appreciate some help.
 * The errors are shown [at this address](http://validator.w3.org/check?uri=http%3A%2F%2Funetquity.co.uk%2F&charset=(detect+automatically)&doctype=Inline&group=0&ss=1)(
   it’s only the first two I’m worried about at this stage)
 * Again, any help much appreciated.
