Có thể bạn thích ?

Trang này chứa danh sách các ký tự đặc biệt HTML. Trong HTML, các ký tự đặc biệt thường là những ký tự không thể gõ dễ dàng vào bàn phím hoặc có thể gây ra sự cố hiển thị nếu được nhập hoặc dán vào trang web.

Nếu bạn dự định sử dụng bất kỳ ký tự đặc biệt nào trên trang này, bạn nên sử dụng tên thực thể HTML hoặc số thực thể HTML. Điều này sẽ đảm bảo rằng nó hiển thị chính xác trong hầu hết / tất cả các trình duyệt.

Ví dụ, nếu bạn muốn hiển thị ký tự bản quyền  “©”, thì bạn nên sử dụng mã là © or © trong code của bạn.

Ký tự dành riêng HTML

Các ký tự đặc biệt sau được bảo lưu trong HTML. Đó là bởi vì đây là những ký tự tạo nên ngôn ngữ HTML. Nếu bạn sử dụng một trong những ký tự này trong một bài viết, trình duyệt sẽ cố gắng diễn giải nó dưới dạng HTML. Do đó, bạn nên sử dụng tên thực thể hoặc số thực thể khi bạn muốn xuất bất kỳ ký tự dành riêng nào.
