Responsively App
One of the most important things for a front-end developer is to focus on how a website can be mobile-responsive and ensure that it fits the right size across different screen sizes. In this post, we'll be looking at Responsively App which is essentially a web browser that is built with electron and has a feature specifically to display the website on multiple screen sizes.

TailwindCSS Playground
The next on the list is TailwindCSS Playground and it's powerful REPL for writing HTML and CSS styling and also testing the responsive breakpoints of the user interface. The panel is divided into the left and the right sections where we code on the left and the result will be displayed on the right side. If there are any custom CSS class, we can define them in the CSS section and it happens instantly without needing a browser reload. Finally, configuration for the default tailwind config is also present on the last tab where we can define an override of the default TailwindCSS config.

Do give it a try and if you have a recommendation, comment below and we'll add it to the list.
