Lithuanian (Lietuvių) is a Indo-European language identified by the ISO 639-1 code "lt". It is spoken by approximately 3 million people, primarily in Lithuania. The language uses the Latin writing system.
In web development, the ISO 639-1 language code is used in HTML lang attributes, HTTP Accept-Language headers, the JavaScript Intl API for locale-aware formatting, and content negotiation. Setting the correct language code improves accessibility for screen readers, enables proper text-to-speech pronunciation, and helps search engines serve content to the right audience. Browsers use this code for spell-checking, hyphenation, and font selection.
For SEO, specifying the content language via the lang attribute and hreflang tags helps search engines understand which language version of a page to show to users in different regions. This is essential for multilingual websites targeting international audiences.
