検証のために次のサイトを送信しましたが、このエラーを受け取りました:
エラー:
No DOCTYPE found! Checking with default XHTML 1.0 Transitional Document Type.
No DOCTYPE Declaration could be found or recognized in this document. This generally means that the document is not declaring its Document Type at the top. It can also mean that the DOCTYPE declaration contains a spelling error, or that it is not using the correct syntax.
The document was checked using a default "fallback" Document Type Definition that closely resembles “XHTML 1.0 Transitional”.
DOCタイプを次のように変更しようとしました:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
ただし、それでもエラーが発生しますか?
どんなアドバイスでも大歓迎です、ありがとう
