It’s a chat-like tool that analyzes your webpage and suggests solutions for styling issues, console errors, and performance hiccups. For this guide, we’ll tackle an overflowing element causing unwanted scrollbars—a classic frontend headache—using the Cinemai DevTools Overflow Demo. With AI assistance, you’ll squash bugs in minutes, no extra tools needed!

Prerequisites

Before we start, ensure you have:

• Latest Chrome Browser: Update via Menu > Help > About Google Chrome.
• Google Account: Sign in (must be 18+ and in a supported region).
• Sample Webpage: We’ll use the Cinemai DevTools Overflow Demo, but you can apply this to any project.
• Basic Web Knowledge: A little HTML/CSS know-how helps, but the AI guides you.

Step-by-Step Guide to Debug with AI Assistance

Step 1: Open Chrome DevTools

Navigate to the Cinemai DevTools Overflow Demo, where a scuba diver image triggers a pesky horizontal scrollbar.

• Right-click on the page and select Inspect, or press F12 (or Ctrl+Shift+I on Windows, Cmd+Option+I on Mac).
• This launches DevTools, your debugging command center.

Step 2: Enable AI Assistance

Unlock AI assistance to debug smarter:

• In DevTools, click the Settings gear icon (top-right) or press F1.
• Go to AI Assistance and toggle it on. Sign in with your Google account and agree to the Terms of Service if prompted.
• Look for the Ask AI button in the DevTools toolbar. If it’s not there, update Chrome to the latest version.

Note: This feature is experimental, so verify AI suggestions. Avoid sensitive data in prompts, as Google may store inputs for up to 18 months (Data Use Policy).

Step 3: Identify the Issue

On the demo page, the scrollbar is caused by the scuba diver image overflowing its container.

• In DevTools, go to the Elements tab.
• Select the image element (e.g., the <div> with a class like page_overflow__B5rjQ).
• Check the Styles pane to pinpoint the issue, likely a fixed width or sizing problem.

Step 4: Ask AI for a Fix

Let AI assistance work its magic:

• Click the Ask AI button to open the chat interface.
• Type: How can I make this element visible without scrollbars?

Example AI response that I got:

To make the element visible without scrollbars, you have a few options:

Change the overflow property: Set overflow: hidden on the element. This will hide any content that overflows its box, preventing scrollbars. However, the overflowing content will not be visible.

Suggested CSS:

article.page_overflow__B5rjQ {
    overflow: hidden;
}

Step 5: Apply the Fix and Capture a Screenshot

Simply click “Set `overflow:hidden` for me” and click “Continue” it will fix that simple issue for you.

Additionally if you want to ask about how to fix with popular library such as “tailwindcss”

Bonus: Try Console Insights for Errors

For JavaScript or network issues, check out Console Insights:

• In the Console tab, hover over an error and click Understand this error.
• The AI explains the issue and offers fixes, ideal for script debugging.
• Enable it in Settings > AI Innovations with the same sign-in steps.
