There are many popular web browsers mostly available for free download such as Internet Explorer by Microsoft, Safari by Apple, Chrome by Google and Firefox an open source offering by Mozilla. All browsers render web pages slightly differently and herein is the problem, as a rule the complex the web page, the more likely you are to run in to the occasional issue. As an operation system such as macOS or Windows ages (without being updated) the browser, which is often integrated in to the OS, can become outdated itself therein increasing the frequency of running into incompatibility issues due to running new code on old browsers.
The best antidote to browser issues is to keep your browser and/or operating system up to date and to stick to the big 4 browsers.
