How Do I Find Hidden Styles in the Shadow DOM?

peeking into shadow DOM to uncover hidden styles

You've stumbled upon a website with an intriguing placeholder color and want to replicate its precise shade. While inspecting the element in Chrome Dev Tools, you've encountered a roadblock: no placeholder-related information is visible.

Fear not, for the secret lies in exploring the shadow DOM. Here's how you can unravel the mystery:

  1. Dive into settings: Begin by clicking the Gear icon in the Chrome Dev Tools panel and selecting the Preferences tab.
  2. Unleash shadow DOM: In the Elements section, locate the checkbox labeled "Show user agent shadow DOM" and check it.
  3. Reveal the hidden realm: With shadow DOM enabled, you'll now see the placeholder element associated with the input element you're inspecting.
  4. Peek into styles: Click on the placeholder element to access its CSS properties and uncover the elusive color specification.

For the specific example you provided, you'll observe that the placeholder element carries the class:

.-webkit-input-placeholder

Investigating its computed styles will reveal the placeholder's color, including alpha values. Now, you're fully equipped to replicate that alluring placeholder color.

What is 'render-blocking CSS'? What is 'render-blocking CSS'? Jun 24, 2025 am 12:42 AM

CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.
