To inspect an element, right-click the part of a webpage you want to examine and select **Inspect**. Your browser opens its developer tools with the rendered HTML element selected and its applied CSS nearby. Changes made there are usually temporary. Runner AI becomes useful when the tested idea should become a saved, reviewable storefront source change rather than disappear on refresh.

> **Key takeaways**
>
> - Use Inspect Element to identify rendered HTML, applied styles, dimensions, and accessibility information.
> - Treat text and CSS edits in the Elements panel as local experiments, not changes to the maintained website.
> - Record the element, route, viewport, property, old value, and approved new value before leaving DevTools.
> - Reproduce only the intended change in the real source file, then review its diff and responsive result.
> - Saving, committing, pushing, and publishing are separate actions in Runner.

## How to open Inspect Element in your browser

The fastest method is to right-click the exact text, image, button, or section you want to examine and choose **Inspect** or **Inspect Element**. This route both opens developer tools and selects the corresponding element. Keyboard shortcuts are useful when the context menu is unavailable or you want to move quickly between the page and its code.

| Browser | Open the selected-element tool | Notes |
| --- | --- | --- |
| Chrome on Windows, Linux, or ChromeOS | `Ctrl+Shift+C` | Opens the Elements panel in selector mode. |
| Chrome on macOS | `Command+Option+C` | Opens the same selector mode. |
| Edge | Right-click and choose **Inspect** | `Ctrl+Shift+I` or `Command+Option+I` opens DevTools, then you can select an element. |
| Firefox | Right-click and choose **Inspect Element** | Opens the Page Inspector with that element selected. |
| Safari on macOS | Use Safari's web inspector | First enable **Show features for web developers** in Safari's Advanced settings. |

Chrome documents the selector shortcuts and current Inspect mode behavior in its [Inspect mode guide](https://developer.chrome.com/docs/devtools/inspect-mode), updated June 29, 2024. Mozilla documents Firefox's right-click and Browser Tools routes in [Open the Inspector](https://firefox-source-docs.mozilla.org/devtools-user/page_inspector/how_to/open_the_inspector/index.html). Apple keeps Safari's prerequisite in [Enabling features for web developers](https://developer.apple.com/documentation/safari-developer-tools/enabling-developer-features). Browser labels can change, so use each browser's current documentation when an option has moved.

Opening DevTools with `F12` or a general shortcut is not always identical to opening selector mode. A general shortcut may reopen whichever panel you used last. The selected-element shortcut activates the pointer tool so you can choose a visible part of the page and jump to its rendered DOM node.

## How to inspect a specific page element

Inspect the smallest element that owns the property you are investigating. Selecting an entire product grid when the problem is one button label gives you more code to search and makes it easier to change the wrong rule.

1. Open the page and reproduce the state you care about, such as a menu being open or a product variant being selected.
2. Activate the element selector in DevTools.
3. Hover over the page until the intended element is highlighted.
4. Click it to select the corresponding node in the Elements panel.
5. Read the element's HTML, classes, attributes, and surrounding structure.
6. Review the applied CSS and note which declaration wins when several rules target the same property.
7. Check the same element at the viewport where the problem occurs; use a broader [responsive website testing workflow](./responsive-website-testing) when the issue crosses routes or breakpoints.

Chrome's Inspect mode overlay can show dimensions, padding, margin, colors, font properties, accessible name and role, keyboard focusability, and some contrast information. Those details help turn “this card feels wrong” into a reproducible observation such as “the product title has 12 pixels of bottom margin at 390 pixels wide, which pushes the button below the card boundary.” Availability and labels differ across browsers, so do not assume every inspector exposes the same fields.

The Elements panel shows the page's current Document Object Model, or DOM. That is the browser's active representation after it has parsed the response and after scripts may have added, removed, or changed elements. It can therefore differ from the raw HTML returned by **View Page Source**. Chrome's [DOM inspection guide](https://developer.chrome.com/docs/devtools/dom/) explains that the DOM tree in the Elements panel represents the page's current structure.

## How to change text or CSS with Inspect Element

Temporary edits are useful because they answer a narrow design question without risking the maintained site. Test one hypothesis at a time so you can reproduce the approved result later.

### Test replacement text

Select the text element, double-click its text node in the Elements panel, enter the replacement, and press Enter. This lets you check whether a headline wraps, whether a button label still fits, or whether clearer copy changes the section's visual balance. It does not update the content system or component that produced the text.

### Test a style change

Select the element and edit a declaration in the Styles panel. Common experiments include color, spacing, font size, line height, width, alignment, and display rules. Disable a declaration before deleting it when you want to understand what that rule contributes. If a property is crossed out, another declaration may have greater precedence or the value may not apply in the current state.

Record a small receipt for any result worth keeping:

- Page route and visible state
- Browser and viewport width
- Selected element or a stable description of it
- Property or text that changed
- Original and approved values
- Screenshot when the visual context matters
- Behavior that must remain unchanged

This record is more useful than copying the entire inspected HTML. A modern page may render markup from components, data, and runtime state, so the browser output is not necessarily the source structure you should edit.

## Why Inspect Element changes disappear

An ordinary Elements-panel edit changes the page loaded in your browser. Reloading usually rebuilds that page from network resources and application code, so the experiment disappears. Microsoft describes Edge's Inspect edits as temporary previews in its [January 16, 2024 learning guide](https://www.microsoft.com/en-us/edge/learning-center/how-to-inspect-elements), and Chrome documents the persistence boundary more precisely.

Chrome supports advanced features called Workspaces and Local Overrides, but they do not turn every Elements-panel edit into a deployed source change. The [Workspaces documentation](https://developer.chrome.com/docs/devtools/workspaces/) says DOM changes made in the Elements tree are not saved to disk. [Local Overrides](https://developer.chrome.com/docs/devtools/overrides/) can preserve local replacements for network resources across reloads, but Chrome also states that DOM changes in the Elements panel are not saved. An override remains a local testing aid, not proof that the maintained repository or live website changed.

That boundary protects you from accidental publication, but it creates a handoff problem: once the browser experiment looks right, you still need to find the real source, make a focused edit, and verify that the application produces the intended result.

## How to turn the experiment into a persistent Runner change

Once an experiment is approved, Runner lets you locate the maintained source, save a focused change, inspect its diff, and verify that it survives a new render. Its conditional code editor reads files from the connected project workspace, tracks unsaved content, saves the active file, and exposes a selected file's Git diff. Inspection does not become automatic; the approved result moves through explicit review steps instead of being mistaken for a live change.

1. **Confirm the storefront and route.** Open the current storefront in Preview and reproduce the element state you inspected.
2. **Choose the right editing surface.** Use Design Mode for a supported focused visual change, ask Runner for a bounded change, or open the conditional code editor when you understand the file you need to inspect.
3. **Read before editing.** Select the relevant file and locate the source that produces the element. Do not paste the browser's generated DOM over a component.
4. **Make the smallest matching change.** Reproduce the approved text or style while preserving data, responsive rules, interactions, and unrelated code.
5. **Save the file.** `Command-S` on macOS or `Control-S` on Windows and Linux writes the active file to the connected project workspace.
6. **Review the Git diff.** Open Git view and select the changed file. Confirm that the diff contains the intended change and no unrelated edits.
7. **Return to Preview.** Check the affected route in **PC**, **Pad**, and **Phone** frames. Repeat the customer action around the element, not just the screenshot.
8. **Commit and push deliberately.** Stage only reviewed files, commit with a clear message, and push only when you are authorized to update the configured remote.
9. **Publish separately.** A saved file, successful preview, commit, or push does not by itself publish the storefront.

The complete control sequence and its failure states are documented in [Inspect and edit storefront code](https://www.runnerai.com/docs/en/guides/storefront-and-publishing/inspect-and-edit-code). If the change is visual and can be selected directly, [Runner's Design Mode guide](https://www.runnerai.com/docs/en/guides/storefront-and-publishing/design-mode) explains the supported focused-edit path. Teams evaluating the broader capability can review the [AI website editor](https://www.runnerai.com/features/ai-website-editor).

| Browser Inspect Element | Runner source workflow |
| --- | --- |
| Changes the current rendered page | Changes a storefront project file |
| Best for diagnosis and quick experiments | Best for an approved change that should survive reloads |
| Usually disappears when the page reloads | Saves to the connected project workspace |
| Does not provide the maintained source diff | Git view exposes the selected changed file's diff |
| Does not publish the website | Save, commit, push, and publish remain separate |

## What to verify before publishing the change

A correct-looking desktop element is not enough evidence for a storefront release. Verify the element in context, including the route into it and the action after it.

- Check mobile, tablet, laptop, and wide layouts when the component can reflow.
- Test hover, focus, active, disabled, loading, error, and empty states that apply.
- Confirm text, price, inventory, links, and policy claims against the system that owns them.
- Use keyboard navigation and inspect the accessible name and role for interactive elements.
- Verify that surrounding navigation, product selection, cart, and checkout entry still work.
- Reload the preview to prove the maintained change survives a new render.
- Review the final diff again before staging or committing.

Runner's [storefront Preview guide](https://www.runnerai.com/docs/en/guides/storefront-and-publishing/preview-your-store) covers route and device-frame checks. If inspection uncovers a site-wide issue rather than one element, the [free website audit tools comparison](./free-website-audit-tools) explains when a page checker, crawler, Lighthouse, or Search Console is the more appropriate source of evidence.

## Inspect Element FAQ

### Is Inspect Element illegal?

Using Inspect Element is an ordinary browser activity; it does not authorize bypassing access controls or testing systems without permission. Do not use it to retrieve protected information or misrepresent a transaction. Follow the site's terms and obtain explicit authorization before security testing. This is practical guidance, not legal advice.

### How do I inspect an element and change its text?

Right-click the text and choose **Inspect**, then double-click its text node in the Elements panel, enter the replacement, and press Enter. The visible result is normally a local prototype. To make it persistent, change the maintained content or source file separately and verify the resulting page.

### How do I inspect an element on Windows 11?

In Chrome or Edge, right-click the element and choose **Inspect**. In Chrome, `Ctrl+Shift+C` opens selector mode directly; `Ctrl+Shift+I` or `F12` opens DevTools. If a general shortcut opens another panel, select the element-picker icon before clicking the page.

### Can I inspect a mobile page?

Desktop DevTools can resize or emulate a mobile viewport for a fast first pass, but emulation does not prove behavior on real mobile hardware or every browser. Use it to find layout and state problems, then verify the highest-risk customer path on a real device. The [responsive testing guide](./responsive-website-testing) explains the limits of viewport simulation and when real-device checks matter.

### Does Inspect Element change the live website?

No, not through the ordinary Elements-panel workflow. It changes the browser's current local representation and normally disappears on reload. A real website change requires updating the maintained source or content, verifying the rendered result, and completing the project's separate release process.

## Move from a browser test to a reviewed storefront update

Use Inspect Element to identify the page node and test a narrow idea without treating the experiment as source truth. When the result is worth keeping, bring the route, viewport, selected element, original value, and approved value into Runner. Make one focused source change, inspect its diff, verify the responsive storefront, and decide separately whether it should be committed, pushed, and published.
