Welcome to the Advent Calendar 2021 on native Web technologies.
This one was created from my collection of useful links and snippets regarding the possibilities of the native browser technologies in 2020/2021. It focuses on using the CSS and JavaScript broadly available as of 2021 and not using frameworks, libraries or polyfills.
Often I found good articles on the internet so I added them as links. Based on my experiences I have also an opinion on many of the technologies and I provice my thoughts and findings in the comments.
What really changed in 2021 is that Microsoft took Internet Explorer from the market and replaced it with Edge based on Chromium. The effect of this was that now is is possible to ignore this below 1% share of IE11 in web application development as the majority of browsers support the same useful set of functionality in HTML, CSS adn JavaScript.
Thanks to Microsoft to open this way after long time driving the web technology (remembering the outstanding IE5).
Now it is time to rething some implementations and have a look on the broadly available features given in the native implementation.
