info i tags found with no class attribute

Explanation

One or more i tags that don't use a class attribute were found in the source code for this page. These tags may cause problems for localization if the content for which they are used has more than one semantic value.

Total number of i tags: 6.

Number of i tags without a class attribute: 6.

What to do

You should not use i tags if there is a more descriptive and relevant tag available. If you do use them, it is usually better to add class attributes that describe the intended meaning of the markup, so that you can distinguish one use from another.
