When debugging something in the elements panel in your developer tools, both Chrome and Firefox's tools allow you to fairly easily take a screenshot of just the selected node. This might come in handy for development, but it's also just a neat way to grab a photo of something on the page with specific boundaries.
In Firefox, you select the node in the Inspector panel, then right-click and choose "Screenshot Node".
Screenshot Node in Firefox Developer Tools
In Chrome it's not as easy to do, but you can find it by selecting the node in the Elements panel, then hitting CTRL-SHIFT-P (or CMD-SHIFT-P on Mac) to open the Command Menu. From there, type "Screenshot" and the menu will display the different screenshot commands available, including the ability to screenshot the selected node.
Screenshot Node in Chrome's DevTools
In the example above, I'm capturing the UL node in the HTML, which will give me a screenshot of the entire unordered list, with its styles on display. This is a simple but effective way to grab a screenshot of a specific part of the page, without the need to manually resize the screenshot to match the size of an element.
Now on to this week's tools!
