How Can I Inspect Webkit-Input-Placeholder Styling Using Dev Tools?

Inspecting Webkit-Input-Placeholder Styling with Developer Tools

When customizing web page elements, it's often necessary to examine the styling applied to other websites. For instance, you may want to mimic the placeholder color used on a specific website.

Can Developer Tools Reveal Placeholders?

By default, inspecting an input element in Chrome Dev Tools does not provide information about its placeholder styling. However, there is a way to access this hidden information.

Accessing Shadow DOM

To uncover the placeholder styling, enable "Show user agent shadow DOM" in the Settings panel of Chrome Developer Tools. Shadow DOM encapsulates elements that are not accessible through the standard DOM and may contain important style information.

Finding the Placeholder

Once shadow DOM is enabled, expand the root element of the input you're inspecting. Inside the shadow DOM, you should find another element representing the placeholder.

Retrieving the Placeholder Color

Click on the placeholder element in the inspector. Its properties will now be visible in the Styles panel. You can find the placeholder's color under the "color" property.

Including Alpha Values

If you need to include alpha values, enable the "Show UA Shadow DOM" setting above the Styles panel. This will expand the placeholder's properties to include its opacity value.

By following these steps, you can effectively inspect the styling applied to webkit-input-placeholders, enabling you to replicate or customize their appearance on your own website.
