Em hãy nêu một số cách để nhận biết siêu liên kết trên trang web.

Phương pháp giải:

Siêu liên kết là một phương thức liên kết từ một nội dung đến một nội dung khác trên web.

Lời giải chi tiết:

Siêu liên kết là một phương thức liên kết từ một nội dung đến một nội dung khác trên web. Nó thường được biểu thị bằng văn bản gạch chân trên một trang web. Khi nhấp vào siêu liên kết, bạn sẽ được chuyển hướng đến URL, hình ảnh, trang web hoặc tệp tin liên kết. Siêu liên kết là cách mà mọi người và các trang web chia sẻ thông tin trên mạng.

Trả lời câu hỏi Hoạt động trang 41 SGK Tin học 12 Cánh diều

Em thường định dạng cho tiêu đề mục của các mục lớn và nhỏ trong một văn bản như thế nào?

Phương pháp giải:

HTML hỗ trợ khai báo sáu tiêu đề mục được phân cấp.

Các phần tử tạo tiêu đề mục được khai báo như sau:

Tiêu đề mục .

Lời giải chi tiết:

HTML hỗ trợ khai báo sáu tiêu đề mục được phân cấp, định nghĩa bởi các phần tử h1, h2, h3, h4, h5 và h6 tương ứng (h là viết tắt của heading và các chữ số cho biết cấp của tiêu đề mục). Các phần tử tạo tiêu đề mục được khai báo như sau: 

Tiêu đề mục  

Trong đó, Cấp của tiêu đề mục là một trong các phần tử h1, h2, h3, h4, h5, h6. 

Theo mặc định, trình duyệt web sẽ hiển thị tiêu đề mục với kiểu chữ in đậm và cỡ chữ khác nhau. Phần tử h1 tạo tiêu đề mục có cỡ chữ lớn nhất, cỡ chữ sẽ giảm dần theo các cấp từ h2 đến h6.
