If the language of a page or on parts of a page is different from the default language of the website, the change needs to be indicated in the HTML code.
What to do?
- Use HTML markup to indicate a language change when you switch to words or phrases that are meant to be read in another language
- For any links to alternative versions of the website/page in another language, use the HTML markup to indicate a language change
- Note that some adopted words can be incorporated into content without calling for a language markup (e.g. the use of siesta to refer to a nap in an English blog)
