Chrome development tool

If you want to focus on a specific property in the Properties pane, you can now type that property name or value in the new Filter textbox. By default, properties whose value is null or undefined are not shown. Enable the Show all checkbox to view all properties. These enhancements allow you to get to the properties you care for quicker and thus improve your productivity!

The forced-colors CSS media feature is used to detect if the user agent has enabled a forced colors mode e. Windows High Contrast mode where it enforces a user-chosen limited color palette on the page. You can now open the Command Menu and run the Show rulers on hover command.

The page rulers make it easier to measure the width and height of an element. The Flexbox editor added two new buttons to support row-reverse and column-reverse in flex-direction. A new shortcut is added in the Search tab allowing you to expand and collapse all the search results.

Previously, you could only expand and collapse the search results by clicking on one file at a time. Enter a search string e.

This can be especially useful when testing and debugging third party plugins. You can test your website and media queries to see if your responsive design is breaking anywhere by going into device mode.

Or perhaps you need to see at what resolution the page is breaking at so you know where to apply a media query. You can then choose what device and resolution to emulate, add a network throttle, and even define the device orientation. The custom color palette will pull from the website style sheet.

You can access them by simply clicking on the color block in the style panel. There is also a color picker that can be used to pick out colors from a web page directly. Have you ever tried to figure out where a hidden style is coming from, say the :hover selector? However, there is something better, called Toggle Element State.

This allows you to force an element state, like :hover , so that you can then use the styles panel to see the properties. You can save any image from a webpage out as a data URI or rather base64 encoded. There is no need to use a free online converter as it is already built into Chrome DevTools. In the Network panel click on an image and then right click on it to have the option to Copy image as data URI. The network filmstrip feature allows you to see how your page renders from start to finish by grabbing screenshots throughout the loading process.

After the page has refreshed it will show you how your page rendered from start to finish. The performance feature allows you to easily see what is costing you the most time and resources. The performance details can be broken down in many different ways, such as the time, activity, and source.

To log a message, you insert an expression like console. When the browser executes your JavaScript and sees an expression like that, it knows that it's supposed to log the message to the Console. Figure 1 shows what the Console looks like after loading the page and waiting 3 seconds.

Try to figure out which lines of code caused the browser to log the messages. The main difference between the methods is how they display the data that you're logging. You can run JavaScript in the Console to interact with the page that you're inspecting.

For example, Figure 2 shows the Console next to the DevTools homepage, and Figure 3 shows that same page after using the Console to change the page's title. Modifying the page from the Console is possible because the Console has full access to the page's window.

DevTools has a few convenience functions that make it easier to inspect a page. For example, suppose that your JavaScript contains a function called hideModal. Snippets are small scripts that you can author and execute within the Sources panel of Chrome DevTools. You can access and run them from any page. When you run a Snippet, it executes from the context of the currently open page. Learn how to evaluate runtime performance in Chrome DevTools.
