Walkthrough

The changes in the pull request enhance both the layout.html and index.html files by adding tabindex attributes to several anchor elements. This modification improves keyboard navigation for accessibility, allowing users to navigate through specific links more efficiently. In layout.html, tabindex values were assigned to links such as "Dashboard," "Refactoring candidates," "Compare with {{ currentView.Comparaison.ComparedBranch }}," and "Help." In index.html, a tabindex="-1" was added to the "All languages" link, along with dynamic tabindex values for language tabs. No changes were made to the underlying logic or styling.

Changes

File Path Change Summary
src/Report/Html/templates/layout.html Added tabindex attributes to four anchor elements for improved keyboard navigation. Links modified: "Dashboard" (tabindex 0), "Refactoring candidates" (tabindex 1), "Compare with {{ currentView.Comparaison.ComparedBranch }}" (tabindex 2), and "Help" (tabindex 3).
src/Report/Html/templates/index.html Added tabindex="-1" to "All languages" link and dynamic tabindex="{{ 4 + forloop.index }}" for language tabs to enhance keyboard navigation.

‼️ IMPORTANT
Auto-reply has been disabled for this repository in the CodeRabbit settings. The CodeRabbit bot will not respond to your replies unless it is explicitly tagged.

  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:

Line range hint 1-2: Add language attribute and skip link for better accessibility

The HTML document is missing crucial accessibility features:

  1. Language attribute for screen readers
  2. Skip link to help keyboard users bypass navigation

Add these improvements:

 <!doctype html>
-<html>
+<html lang="en">
 <head>
+    <style>
+        .skip-link {
+            position: absolute;

+            left: 0;
+            background: #000;
+            color: white;
+            padding: 8px;
+            z-index: 100;
+        }
+        .skip-link:focus {
+            top: 0;
+        }
+    </style>
 </head>
 <body>
+    <a href="#main-content" class="skip-link">Skip to main content</a>
     <div class="grid grid-cols-7">

Then add the corresponding ID to the main content:

+        <main id="main-content" class="col-span-6">

Line range hint 92-119: Improve share button accessibility

The share functionality lacks proper accessibility features and keyboard support.

Line range hint 13-38: Enhance tab navigation accessibility

The language tabs section could benefit from additional ARIA attributes to improve screen reader support.

Consider these accessibility enhancements:

     <!-- start: language tabs-->
-    <div class="flex overflow-x-auto overflow-y-hidden border-b border-gray-200 whitespace-nowrap ">
+    <div role="tablist" class="flex overflow-x-auto overflow-y-hidden border-b border-gray-200 whitespace-nowrap ">
         <a 
             tabindex="0"
             href="index.html"
+            role="tab"

⚠️ Potential issue

Avoid using positive tabindex values

Using positive tabindex values (>0) is discouraged by accessibility best practices as it creates a custom tab order that might not match the visual/logical flow of the page. This can be confusing for keyboard users and screen readers.

Consider this alternative:

-                tabindex="{{ 4 + forloop.index }}"
+                tabindex="0"

The natural DOM order of elements should dictate the tab sequence. If you need to change the tab order, consider restructuring the HTML instead.

Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

⚠️ Potential issue

Reconsider using tabindex="-1" for the "All languages" link

Setting tabindex="-1" removes this element from the natural tab order, which may harm accessibility. As this is the primary language selection option, users should be able to navigate to it using the Tab key.

Consider one of these alternatives:

-            tabindex="-1"
+            tabindex="0"

or simply remove the tabindex attribute to keep it in the natural tab order:

-            tabindex="-1"
