Inspecting Placeholder Colors in WebKit
It's common knowledge that placeholder text in text inputs can be styled using the -webkit-input-placeholder CSS property. However, determining the exact color used by a website can be challenging when using a conventional image editor.
To overcome this, Chrome Dev Tools provides a solution:
Step 1: Enable "Show User Agent Shadow DOM"
By enabling this option in the Chrome Dev Tools settings (Preferences > Elements > "Show user agent shadow DOM"), you'll be able to inspect placeholder elements indirectly through the shadow DOM.
Step 2: Locate the Placeholder Element
Once enabled, you can inspect the input element and locate the placeholder element within its shadow DOM. This can be identified by styles like -webkit-input-placeholder.
Step 3: Determine the Placeholder Color
With the placeholder element selected, you can now view its computed styles, including the placeholder color. This includes any alpha values, providing a specific and accurate representation of the color used.
Conclusion:
By understanding how Chrome Dev Tools handles shadow DOM, you can effectively inspect placeholder elements and retrieve specific color information, regardless of how it's applied to the website.
