-T> Browsers are developed to try and reduce used bandwidth as much as possible. If you request a page multiple times, it is likely that after the initial request, the content you see will be stored in a *browser cache* on your computer. This means that when developing your project (and changing things rapidly), content may not be refreshed with the most up-to-date implementation. The solution to this problem is to either clear your browser's cache, or to perform a [*hard refresh*](https://refreshyourcache.com/en/cache/). The command you issue depends on your browser and operating system. Windows systems should work with CTRL+F5, with Macs using CMD+SHIFT+R.
