概述
无障碍 Tab 顺序工作流是一个初级难度的工作流。验证并修复键盘 Tab 顺序，确保所有交互元素可仅用 Tab 键按逻辑顺序到达。该工作流的目标是：Ensure all interactive elements are reachable via keyboard in a logical order.
环境准备
执行本工作流需要以下环境：A web application with interactive elements；A keyboard for testing；Browser developer tools。请确保在开始前准备好所有必需的工具和资源，以避免中途因环境问题中断。
执行步骤
本工作流包含4个步骤。步骤1：Tab through the page——Press Tab repeatedly to traverse all interactive elements and note the order. 步骤2：Identify issues——Note any elements that are skipped, trapped, or out of logical order. 步骤3：Fix tabindex——Adjust tabindex values or restructure the DOM to achieve logical tab order. 步骤4：Verify fixes——Tab through the page again to confirm the order is now logical and complete.
验证与清理
预期结果：All interactive elements are reachable via keyboard in a logical, predictable order.。验证方法：Tab through the entire page and confirm every interactive element is reached in the expected order.。清理操作：No cleanup needed; tabindex changes should be committed.。estimatedMinutes 为 25 分钟。
