  blog, from whence the sounds of battle can be heard. To the east
  you can see a large mountain, upon which many school papers are littered. Far up thus mountain
  you can spy a little figure who appears to be me, desperately
  scribbling a thesis.
  To the west are several exits. One fun-looking exit is labeled "games". Another more
  boring-looking exit is labeled ISP™.
  To the south lies a dark and dank contacts

Còn rất nhiều điều để tìm hiểu về thuật toán phác thảo tài liệu. Tôi sẽ dừng lại ở đây bởi vì…

Không có trình duyệt nào hỗ trợ thuật toán phác thảo tài liệu

Không có một trình duyệt nào hỗ trợ phương pháp tạo cấu trúc tiêu đề này. Đây là một sự xấu hổ. Việc xây dựng các trang web có thể truy cập sẽ dễ dàng hơn nhiều nếu chúng ta không phải lo lắng quá nhiều về việc sử dụng cấp tiêu đề chính xác mọi lúc

Theo như tôi biết, có hai lý do chính khiến không có trình duyệt nào triển khai thuật toán. Một là các nhà cung cấp trình duyệt sợ phá vỡ cấu trúc tiêu đề của các trang web đã sử dụng các thành phần phân đoạn không chính xác. Lý do khác là thông số thuật toán phác thảo tài liệu hiện tại rất khó triển khai và chưa có nhà cung cấp trình duyệt nào sẵn sàng dành thời gian để triển khai nó

327 này. Việc thiếu phân cấp tiêu đề này sẽ khiến trình soạn thảo văn bản có định dạng CMS trở nên quá khó sử dụng đối với khách hàng

Đối với vấn đề xung quanh độ khó triển khai, công việc đang được thực hiện để tạo ra một thông số kỹ thuật đơn giản hóa mà các nhà cung cấp trình duyệt có nhiều khả năng áp dụng hơn. Thuật toán phác thảo tài liệu đã có trong thông số kỹ thuật HTML trong nhiều năm. Hy vọng thông số kỹ thuật đơn giản hóa này sẽ cho phép thuật toán trở thành hiện thực

Mặc dù thuật toán chưa được hỗ trợ ở bất kỳ đâu nhưng chúng ta vẫn có thể xây dựng dựa trên thuật toán. Nếu chúng ta xây dựng với nó trong tâm trí, thì chúng ta sẽ đạt được những lợi ích sau

Chúng tôi chứng minh các trang web của mình trong tương lai trong trường hợp thuật toán được triển khai
Chúng tôi có thể cải thiện đáng kể trải nghiệm người dùng cho người dùng trình đọc màn hình
Chúng tôi có khả năng cải thiện tối ưu hóa công cụ tìm kiếm (SEO) do các công cụ tìm kiếm có thể hiểu rõ hơn nội dung của trang web
Chúng tôi có thể tạo trải nghiệm người dùng tốt hơn cho người dùng bằng cách cho phép họ sử dụng các tính năng gốc của trình duyệt sử dụng các thành phần phân đoạn, như Chế độ đọc

353 không được sử dụng để gắn nhãn các phần tử phân chia

Các phần tử phân đoạn yêu cầu nhãn để người dùng trình đọc màn hình có thể nhanh chóng xác định nội dung họ có thể tìm thấy bên trong phần cụ thể đó của trang web. Tôi cân nhắc việc sử dụng các phần tử phân chia mà không cung cấp các nhãn phần được liên kết vì khả năng truy cập không thành công, trừ khi đó là phần tử duy nhất thuộc loại này trên trang. Cũng không nên sử dụng cùng một văn bản nhãn trên nhiều thành phần phân đoạn (hoặc thành phần tiêu đề). Điều này làm cho mỗi phần dễ nhận biết hơn đối với người dùng trình đọc màn hình, giúp họ điều hướng trang web dễ dàng hơn

Có ba cách để gắn nhãn một phần tử phân đoạn. Trong các ví dụ sau, tôi đề cập đến “vận chuyển” và “tính di động” như một cách giải thích việc lưu phần đó vào một thành phần dễ dàng như thế nào và sử dụng thành phần đó nhiều lần trong nhiều ngữ cảnh khác nhau

Tôi cũng cung cấp danh sách các mặt tích cực và tiêu cực trong các ví dụ. Trong các danh sách này, tôi giả sử rằng bạn muốn trình đọc màn hình có thể đọc được nhãn phần nhưng ẩn đối với người dùng có thị lực

Phương pháp 1. Thêm một thuộc tính nhãn aria

85 (tại thời điểm viết) là hầu hết các trình duyệt không thể dịch các giá trị này cho người dùng nói ngôn ngữ khác với bạn. Các nhà phát triển tại Google gần đây đã sửa lỗi này trong Chrome, tuy nhiên đây vẫn là vấn đề đối với mọi trình duyệt khác

Nếu trang web của bạn có lượng người xem quốc tế lớn hoặc bạn biết rằng nhiều người dùng không nói được ngôn ngữ của bạn, thì có lẽ bạn nên tránh sử dụng thuộc tính này cho đến khi tất cả các trình duyệt hỗ trợ bản dịch của thuộc tính này. Nếu bạn không có những loại người dùng đó, sẽ khá an toàn khi cho rằng những người dùng khiếm thị đang xem trang web của bạn có thể hiểu ngôn ngữ của bạn — dù sao cũng đủ để có thể điều hướng trang web của bạn

Nếu bạn cần thuyết phục hơn, giả sử trang web của bạn có rất ít người dùng quốc tế. Điều đó có nghĩa là người dùng của bạn thường đến từ cùng một quốc gia với bạn. Nếu họ đến từ cùng một quốc gia thì có khả năng họ sẽ nói cùng ngôn ngữ với bạn, do đó, đã có một tỷ lệ khá nhỏ người dùng không hiểu ngôn ngữ mẹ đẻ của trang web của bạn.

Chỉ một tiêu đề ở mức cao nhất cho mỗi phần tử phân đoạn

Thực sự chỉ nên có một tiêu đề cấp cao nhất trong phần tử phân đoạn. Thông số kỹ thuật nói rằng khi có nhiều tiêu đề cấp cao nhất hoặc tiêu đề cấp cao hơn tiêu đề đầu tiên, trình duyệt phải đóng phần tử phân đoạn trước đó và bắt đầu một tiêu đề mới cùng loại

Phần tử đầu tiên của nội dung tiêu đề trong một phần tử của nội dung phân đoạn đại diện cho tiêu đề cho phần rõ ràng đó. Các tiêu đề tiếp theo có thứ hạng bằng hoặc cao hơn bắt đầu các phần phụ ngụ ý mới là một phần của phần chính của phần trước. Các tiêu đề tiếp theo có thứ hạng thấp hơn bắt đầu các tiểu mục ngụ ý mới là một phần của tiểu mục trước đó. Trong cả hai trường hợp, phần tử đại diện cho tiêu đề của phần ngụ ý
—HTML 5. 3, Tiêu đề và Mục

Trong thực tế, trình duyệt sử dụng tiêu đề đầu tiên làm nhãn phần nhưng các phần ngụ ý này không bao giờ được tạo. Nó chỉ thông báo tiêu đề như khi nó gặp nó. Nó không tệ đến mức kinh hoàng nhưng nó hơi khó hiểu

83, thì tiêu đề cấp cao nhất đó phải luôn là phần nội dung đầu tiên bên trong phần tử phân đoạn đó. Không làm như vậy được tính là khả năng truy cập không thành công

Nếu bạn thấy mình cần đặt nội dung trước tiêu đề của mình (chẳng hạn như hình ảnh), bạn có thể sử dụng Flexbox để sắp xếp lại thứ tự trực quan. Điều này sẽ cho phép nó trông giống như hình ảnh xuất hiện trước tiêu đề nhưng trong phần đánh dấu, tiêu đề xuất hiện trước hình ảnh.

Lưu ý rằng việc sắp xếp lại thứ tự trực quan để đáp ứng Nguyên tắc 1 của WCAG. 3. 2. Trình tự có ý nghĩa có thể xung đột trực tiếp với Hướng dẫn 2 của WCAG. 4. 3. Thứ tự tập trung. Ví dụ: nếu hình ảnh đó là một liên kết đến một bài viết và tiêu đề bạn đặt ở trên cũng là một liên kết đến bài viết, thì việc đặt tiêu đề trước sẽ phá vỡ thứ tự tiêu điểm. Đặt hình ảnh đầu tiên phá vỡ chuỗi ý nghĩa

Trong những tình huống như thế này khi hai hướng dẫn này xung đột với nhau, ý kiến của tôi là 1. 3. 2. Hướng dẫn Trình tự có ý nghĩa là hướng dẫn quan trọng hơn cần tuân theo nếu bạn không thể giải quyết xung đột theo một cách nào đó. Thứ tự tiêu điểm không thành công dẫn đến người dùng cảm thấy khó chịu khi họ đang lướt qua nội dung và tiêu điểm được gửi đến một vị trí không mong muốn. Việc không tuân theo một trình tự có ý nghĩa dẫn đến việc người dùng bối rối không chắc chắn về mối quan hệ giữa các phần nội dung khác nhau

Tạo nhãn phần ẩn trực quan ra khỏi tiêu đề

Các tiêu đề được hiển thị cho người dùng sáng mắt theo mặc định. Điều này làm cho chúng trở nên cực kỳ hữu ích nếu bạn muốn hiển thị tiêu đề. Trong nhiều trường hợp, chúng tôi không muốn nhãn cho phần tử phân vùng của chúng tôi hiển thị. Để ngăn người dùng sáng mắt của chúng tôi nhìn thấy nhãn, chúng tôi cần sử dụng một số CSS

Các tiêu đề được hỗ trợ tốt bởi các công cụ phân tích cấu trúc

Các tiêu đề cũng có một lợi thế rất lớn cho các nhà phát triển ở chỗ bất kỳ công cụ phân tích cấu trúc trang nào bạn có thể tìm thấy sẽ có hỗ trợ cho chúng. Điều này làm cho cấu trúc tiêu đề dễ kiểm tra và gỡ lỗi. Hai phương pháp ghi nhãn phần khác có hỗ trợ rất kém trong các công cụ kiểm tra.

Như bạn có thể thấy, cấu trúc trang web trở nên khá rõ ràng và dễ hiểu đối với người dùng trình đọc màn hình khi bạn tính đến tất cả thông tin ngầm bổ sung mà bạn nhận được từ việc sử dụng cấu trúc HTML tốt

Vì vậy, mặc dù không có trình duyệt nào hỗ trợ thuật toán phác thảo tài liệu, nhưng vẫn đáng để nỗ lực suy nghĩ về dàn bài. Trình đọc màn hình vẫn cho người dùng biết loại phần nào đó, phần bắt đầu ở đâu và (đôi khi) kết thúc (tùy thuộc vào trình đọc màn hình) và nhãn phần là gì. Điều này có nghĩa là những nỗ lực của bạn để tạo ra một cấu trúc tài liệu tốt sẽ không bị lãng phí

Loại cấu trúc này đi kèm với nhiều lợi ích

Trang tương thích 100% với thuật toán phác thảo tài liệu, sẽ chứng minh điều đó trong tương lai trong trường hợp thuật toán được triển khai trong một trình duyệt thực
Cấu trúc đề mục hoàn toàn logic
Người dùng trình đọc màn hình điều hướng qua các tiêu đề có thể nhanh chóng chuyển đến thông tin quan trọng
Người dùng trình đọc màn hình điều hướng qua các mốc có rất nhiều mốc hữu ích để di chuyển trên trang
Người dùng trình đọc màn hình có thể nhanh chóng hiểu nội dung của từng phần mà không cần phải đọc bất kỳ nội dung nào bên trong chúng
Nội dung được nhóm thành các phần ngữ nghĩa, vì vậy người dùng trình đọc màn hình không bị nhầm lẫn khi rời khỏi phần này và vào phần khác
Các công cụ tìm kiếm có thể hiểu rõ hơn thông tin mà mỗi phần chứa, điều này có khả năng cải thiện SEO
Người dùng sáng mắt có thể tận dụng các tính năng của trình duyệt gốc như Chế độ đọc

Tiện ích mở rộng này sẽ cho phép bạn dễ dàng xem cả biểu diễn cấu trúc tiêu đề phẳng của trang web của bạn (i. e. tất cả các trình duyệt hiện đọc cấu trúc tiêu đề như thế nào) và cấu trúc tài liệu trông như thế nào trong trình duyệt hỗ trợ thuật toán phác thảo tài liệu (i. e. cách một trình duyệt lý thuyết trong tương lai hỗ trợ thuật toán phác thảo sẽ trình bày cấu trúc trang web). Trước tiên, chế độ xem Phác thảo HTML5 cần được bật trong menu cài đặt. Điều này là để ngăn người dùng bị lừa nghĩ rằng họ có thể sử dụng thuật toán phác thảo trong các trang web sản xuất

Sau khi bạn có một công cụ kiểm tra cấu trúc tài liệu tốt, hãy kiểm tra xem cả cấu trúc tiêu đề và bố cục tài liệu có hiển thị theo thứ tự hợp lý không thiếu tiêu đề hoặc nhãn phần bị thiếu ở bất kỳ đâu

Tải xuống và sử dụng trình đọc màn hình

Cách tốt nhất để kiểm tra ngữ nghĩa ngụ ý mà bạn nhận được từ việc sử dụng đúng HTML là tải xuống trình đọc màn hình thực tế và thử điều hướng trang web của bạn bằng trình đọc đó. NVDA là một trong những trình đọc màn hình được sử dụng nhiều nhất bởi những người dùng trình đọc màn hình thực. Nó cũng miễn phí

Xin lưu ý rằng cài đặt mặc định cho NVDA được tối ưu hóa để người dùng khiếm thị sử dụng. Các cài đặt mặc định này có thể khiến người dùng sáng mắt phát điên. Để tận hưởng thời gian sử dụng NVDA, hãy thực hiện các bước sau (các bước dựa trên thiết lập Windows, tôi không có máy Mac)

Tải xuống NVDA và cài đặt nó
Tạo lối tắt đến NVDA trên thanh tác vụ của bạn (Bạn sẽ mở và đóng nó thường xuyên trong khi thử nghiệm)
Mở NVDA từ thanh tác vụ
Tìm NVDA trong khay hệ thống của bạn (xem bên dưới)
Nhấp chuột phải vào biểu tượng khay > “tùy chọn” > “cài đặt”
Chọn “chuột” trong bảng điều khiển bên trái
Bỏ chọn “Bật tính năng theo dõi chuột” (Bây giờ bạn có thể di chuyển chuột mà không cần NVDA hét vào mặt)
Nhấn OK"
Nhấp chuột phải vào biểu tượng khay > “Công cụ” > “Trình xem giọng nói” (Bây giờ bạn có thể xem nhật ký mọi thứ NVDA nói, tuy nhiên đừng hoàn toàn dựa vào điều này khi thử nghiệm)
Trong Speech Viewer, đánh dấu hộp kiểm “Show Speech Viewer on Startup” (Hiển thị Speech Viewer khi bạn mở NVDA)
Làm quen với một số phím điều khiển
Để đóng NVDA, Nhấp chuột phải vào biểu tượng khay > “Thoát” > “OK”

5 dường như đã giảm vì một số lý do. Điều này có nghĩa là NVDA phải được sửa. Điều đó không có nghĩa là bạn nên ngừng sử dụng đúng ngữ nghĩa trong HTML của mình

Xây dựng trang web của bạn dựa trên phác thảo tài liệu, sau đó kiểm tra ngữ nghĩa bằng Bản đồ tiêu đề và NVDA (hoặc trình đọc màn hình khác). Nếu bạn làm như vậy, bạn sẽ làm cho người dùng trình đọc màn hình của bạn rất hài lòng. Bạn thậm chí có thể làm cho các công cụ tìm kiếm hài lòng hơn. 😊

  you can see a large mountain, upon which many school papers are littered. Far up thus mountain
  you can spy a little figure who appears to be me, desperately
  scribbling a thesis.
  To the west are several exits. One fun-looking exit is labeled "games". Another more
  boring-looking exit is labeled ISP™.
  To the south lies a dark and dank contacts
  page. Cobwebs cover its disused entrance, and at one point you
  see a rat run quickly out of the page.
