The Unsung Hero: Why You Should Care About DevTools
Hey there, fellow developer! 👋 If you’re anything like me, you probably spend a good chunk of your day with the developer tools open. Whether you call them DevTools, Inspector, or just the “F12 thingy,” they’re a fundamental part of our daily workflow. But let’s be honest, for many of us, our DevTools usage is pretty basic. We use it to inspect an element’s CSS or to check for errors in the console. And that’s fine—it gets the job done.
However, Chrome DevTools is a lot more powerful than you think. It has a ton of hidden gems that can save you hours of head-scratching, improve your debugging flow, and even help you write cleaner code. In this post, I’m going to share 14 powerful Chrome DevTools tricks that will make you a more efficient and confident developer in 2025.
Let’s dive in!
1. The Visual CSS Shadow Editor | Chrome DevTools Tricks
Ever wanted to add a box-shadow but got tired of tweaking the values manually? There’s a better way! Instead of guessing the right blur, spread, and position values, you can use the built-in visual editor.
- Inspect the element you want to add a shadow to.
- Find an existing
box-shadowin the Styles panel, or add a new one. - Click the small icon next to the shadow’s value.
- A visual editor will pop up, allowing you to drag sliders to adjust the shadow’s position, blur, and spread. You can even toggle it to an
insetshadow.
This feature is a huge time-saver and lets you see the effect of your changes in real-time. Once it looks perfect, just copy the CSS code and paste it into your stylesheet.
2. Ditch console.log with Log Points | Chrome DevTools Tricks
We’ve all been there: a JavaScript bug appears, and our first instinct is to sprinkle console.log everywhere. While it works, it also clutters your code. A much cleaner alternative is using Log Points.
- In the Sources panel, navigate to your JavaScript file.
- Right-click next to the line number where you want to log something.
- Choose “Add log point.”
- Type your message and any variables you want to inspect (e.g.,
'User ID:', userId).
Code Example:
JavaScript
// A simple function to demonstrate a log point
function getUserProfile(userId) {
// Add a log point here: 'Fetching profile for user:', userId
fetch(`https://api.example.com/users/${userId}`)
.then(response => response.json())
.then(data => {
console.log('Profile data:', data);
});
}
The best part? It works just like a console log, but you don’t have to touch your actual code. Plus, these log points persist across page reloads, which is super handy for debugging tricky issues. For even more control, you can also set Conditional Breakpoints that only pause your code when a specific condition is met!
3. Measure Your Code with the Coverage Tool | Chrome DevTools Tricks
Is your website loading a lot of unnecessary JavaScript or CSS? You’d be surprised how often that happens, especially with large frameworks or third-party libraries. The Coverage tool is a must-have for figuring this out.
- Open the Command Palette (
Ctrl + Shift + PorCmd + Shift + P). - Type “coverage” and select “Show Coverage.”
- Click the reload button to start recording.
The tool will now show you a live breakdown of how much of your CSS and JavaScript files are actually being used. It’s a fantastic way to identify “dead” code that can be lazy-loaded or removed entirely to improve your site’s performance. Seeing a file with 90% unused code is a powerful motivator to refactor!
4. Break on DOM Changes | Chrome DevTools Tricks
Have you ever seen an element on your page change its classes or get removed without any idea why? It’s a common issue, especially when working with third-party scripts or complex frameworks. The Break on DOM change feature is your new best friend.
- In the Elements panel, right-click on the DOM node you want to monitor.
- Select “Break on.”
- Choose from three options:
- Subtree modifications: Pauses when a child element is added or removed.
- Attribute modifications: Pauses when an attribute (like
classorid) is changed. - Node removal: Pauses when the element itself is removed from the DOM.
This trick is pure gold. It immediately pauses the JavaScript execution at the exact line of code responsible for the change, saving you from a tedious debugging session.
5. Emulate a Focused Page | Chrome DevTools Tricks
You’re trying to inspect a dropdown menu, but the moment you click on the DevTools window, the menu closes! Frustrating, right? There’s a tiny checkbox in the Rendering tab that solves this.
- Open the Command Palette (
Ctrl + Shift + PorCmd + Shift + P). - Type “rendering” and select “Show Rendering.”
- Check the “Emulate a focused page” option.
Now, your website will behave as if it’s still the active window, even when you’re clicking around in the DevTools. This is a subtle but incredibly useful trick for debugging tricky UI states.
6. The Rendering Tab for Accessibility & Performance | Chrome DevTools Tricks
Speaking of the Rendering tab, it’s packed with other powerful features. This is your go-to place for simulating different user conditions.
- Simulate print media: See how your site looks when someone tries to print it.
- Emulate vision deficiencies: See your site through the eyes of users with conditions like color blindness. This is a critical feature for building accessible websites.
- Highlight ares that might cause performance issues: The
Scrolling performance issuesoption highlights elements that might be causing performance bottlenecks.
These tools are essential for building a robust and inclusive web presence.
7. Tidy Up Your Code with the CSS Overview | Chrome DevTools Tricks
If you’re dealing with a large stylesheet, it can be hard to keep track of all the different colors, fonts, and sizes you’re using. The CSS Overview is a fantastic tool for getting a high-level summary.
- Open the Command Palette (
Ctrl + Shift + PorCmd + Shift + P). - Type “CSS Overview” and select “Show CSS Overview.”
- Click “Capture overview.”
You’ll see a report with a summary of:
- Colors: A list of every color used on your site. This can help you identify redundant or inconsistent shades.
- Font Info: An overview of all the font families, sizes, and weights in use. This is perfect for cleaning up inconsistent typography.
- Unused Declarations: It even points out CSS rules that aren’t being applied anywhere, so you can clean them up.
This feature is great for ensuring a consistent and clean design system.
8. Capture Full-Size Screenshots | Chrome DevTools Tricks
Tired of stitching together multiple screenshots to capture an entire webpage? Don’t. DevTools has you covered.
- Right-click on the
<body>element in the Elements panel. - Select “Capture node screenshot.”
This will save a full-size image of the entire page to your computer, even if it’s a long, scrolling page. Alternatively, you can open the Command Palette and type “Capture full size screenshot” for the same result.
9. Copy The Entire Console to Your Clipboard | Chrome DevTools Tricks
Need to share a long list of console logs with a teammate or an AI debugging tool? Instead of manually selecting and copying each line, just right-click anywhere in the Console and select “Copy console.” It copies the entire log history to your clipboard in one go.
10. Debug CSS Animations with the Animations Tab | Chrome DevTools Tricks
CSS animations can be tricky to debug. The Animations tab gives you complete control over them.
- Go to the three-dot menu, select “More tools,” then “Animations.”
- As long as the tab is open, it will record all animations on the page.
- You can then replay, slow down, or scrub through the animation timeline to inspect each keyframe.
- It also shows you the animated elements, so you can jump straight to the code.
This tool makes understanding and tweaking complex animations a breeze.
11. Test Network Throttling for Slow Connections | Chrome DevTools Tricks
How does your app behave on a slow internet connection? This is a crucial question for building a good user experience. The Network tab’s throttling feature lets you find out.
- Go to the Network tab.
- Look for the dropdown menu that says “No throttling.”
- Choose a preset like “Slow 3G” or “Fast 3G.”
This will simulate a slower connection, allowing you to test if your loading spinners, fallback states, and error messages are working correctly. It’s also useful for debugging race conditions or concurrency issues that only appear when requests take a long time to resolve.
12. The debugger Keyword for Quick Pauses | Chrome DevTools Tricks
Need to pause your JavaScript code at a specific point without going into the DevTools and setting a breakpoint? Just add the debugger keyword directly into your code.
Code Example:
JavaScript
function processData(data) {
// A quick way to pause execution
debugger;
// ... rest of your code
}
When your browser’s JavaScript engine hits this keyword, it will automatically pause execution and open the debugger in the Sources panel. It’s a quick and dirty trick for temporary debugging that you can easily remove later.
13. Save Your Scripts with Snippets | Chrome DevTools Tricks
Do you have little bits of JavaScript you run in the console all the time? Don’t keep re-typing them! Save them as a Snippet.
- In the Sources tab, click on the “Snippets” panel.
- Click “New snippet” and give it a name.
- Paste your JavaScript code into the editor.
- To run it, right-click the snippet and select “Run.”
Snippets are stored persistently in your browser, so you can access them anytime you need to. You can use them for anything from listing all links on a page to visually highlighting layout elements. It’s like having your own mini-extension library for quick tasks.
14. A Quick-Tip to Empty Cache and Hard Reload | Chrome DevTools Tricks
Sometimes, a simple refresh isn’t enough to see your latest changes because the browser is loading an older version from its cache. To fix this, just long-click the reload button in the browser’s toolbar. You’ll see an option to “Empty cache and hard reload.” It’s a lifesaver when you’re sure your code is right but the page just won’t update!
