web-development / webdeveloper

Webdevelopment is a broad term for creating a website to be published on the internet or intranet. It includes design, content-creation, usage of scripting languages, network configuration, security-handling, performance-management (like speed and stability), user-experience and many other tasks.
Often a website is being maintained by different specialists; subjects like security and Search Engine Optimalisation (SEO) are not primairily enclosed in webdevelopment as things are changing rapidly, which generally means that a lot of research is involved to keep up with the dynamics of the internet.

There are three kinds of webdevelopers (webdevs): front-end, back-end and full-stack.
Front-end webdevs take care of how the website looks to the outside world, they mainly use three scripting languages: HTML, CSS and javaScript. HTML can be seen as the mainframe: it contains the text, the images and the main-layout, where CSS is being used for styling these HTML-elements (color, font, sizes, responsiveness etc.) and javaScript for adding interaction, create effects, animations, games, utilities etc.
Back-end (web)devs have the task to make the website run smoothly, fast and stable. They manage the hosting services, databases, security and more complex applications. They use scripting languages like Python, Ruby, Java, PHP etc.
A full-stack webdev is a person who knows a lot about front-end ánd back-end scripting, preferably combined with system-administration(Operating System, Server-management etc.) and who can work completely solitairy.

<web-manifest>

HTDML-tag as mentioned in the HTDML-custom-tag-table and the custom-tagtable-stylesheet.

This tag is a very personal one. I make websites since 1997 and I have seen the web change from a fun place to be to a money-making machine for huge corporates who don't like personal webpages, especially when the webmaster does not want to conform to their rules. In my opinion they stole the web from the people and try to ban everyone who does not behave like they want them to.

Really: the web is by far not what it used to be and it has become hunting grounds for personal data and manipulation driven by corporate greed only.

I have been thinking about writing a huge web-manifest about all this and then he idea cam e to me to make a custom-tag for it. That way I can rant about my grievings everywhere I feel I need to, just by using my own <web-manifest>-HTML custom tag. I gave it some nice color-tints and border of which I think is suitable.

Here it goes, the <web-manifest>:

Web-scripting virus

A web-scripting virus is a virus that breaches the browsers' security and makes it behave in a different way. It can change the starting page, generate pop-up screens and infect the local machine in a way that it becomes slow and almost unusable.

This kind of virus has the ability to spread very fast, infecting lots of devices. Mostly people "catch" this virus by opening attachments, visiting certain websites, clicking on a link or downloading software.
