today i learned: svg files are literally just html code
-
what the heck!! that is so wild, mind blowing, i know the main difference between raster graphics and vector graphics was the quality but not more, i had no idea svg files actually used html code and pretty much could be modified using only text and amazing code woa!!! this opens up the possibility for so many things on linux i think, for example, on a linux distro, we could modify the desktop environment and make it waaaaay lighter by getting rid of jpg or png icons and just using pure svg on it. svg can be given a lot of attributes like movement, mouse hovering, change color, change anything. and most svg files are still under a megabyte. wow.. please let me know other fun facts about svg or eps files. i really like doing graphic design on linux and inkscape.

More precisely, both are flavors of XML.

technically HTML is not XML.. XHTML is, but HTML can be invalid XML.

Age doesn't matter. XML is a super-set of XHTML's spec.
That is - all XHTML is valid XML but not all XML is valid XHTML.
Note I'm saying XHTML not HTML since the later need not be valid XML.

Ok—to the extent that SVG is HTML, the variant of HTML that it is is a flavor of XML.

Another interesting part is that HTML5 supports embedding SVG. That
is, you can put SVG code directly in your HTML5 document and it’s
going to render correctly. You can also style it through your
website’s CSS file and manipulate the elements via JavaScript.Though as others pointed out, it’s technically not HTML but XML.

woww that is crazy, thanks, does that mean that instead of using exported pngs, i can just use the svg code on html and it'll be a much lighter file??

If you have an SVG image you can either embed it directly on the website, or link it using
imgtag. There’s no need to export it to PNG. -

Damn, I actually did not know that. I thought it was just an image file.

litghter, as in smaller, yess. but keep in mind, that vector graphics need to be rendered, wich depending on circumstance and graphic might become inefficient.
i never crunched the numbers, but basically youre outsourcing the generation of a rastergraphic to those who open up your website.

That's a weird way of saying XHTML is an application of XML.

It's both of those things

It's not. The primitives, the most basic constitutive building blocks, are different, for raster it's the pixel (a mix of colors, e.g. red/green/blue) whereas for vector it's the ... vector (a relative position elements, e.g. line, circle, rectangle or text start with).
This is a fundamental distinction on how you interact with the content. For raster you basically paint over pixels, changing the values of pixels, whereas for vector you change values of elements and add/remove elements. Both can be lossless though (vector always is) as for raster can have no compression or lossless compression. That being said raster does have a grid size (i.e. how many pixels are stored, e.g. 800x600) whereas vector does not, letting you zoom infinitely and see no aliasing on straight lines.
Anyway yes it's fascinating. In fact you can even modify SVG straight from the browser, no image editor or text editor needed, thanks to your browser inspector (easy to change the color of a rectangle for example) or even the console itself then via JavaScript and
contentDocumentyou can change a lot more programmatically (e.g. change the color of all rectangles).It's a lot of fun to tinker with!

They can include runnable JavaScript too, which can cause vulnerabilities in certain contexts. One example from work some years back: We had a web app where users could upload files, and certain users could view files uploaded by others. They had the option to download the file or, if it was a file type that the browser could display (like an image or a PDF), the site would display it directly on the page.
To prevent any XSS (scripts from user-provided files), we served all files with the CSP sandbox header, which prevents any scripts from running. However, at the time, that header broke some features of the video player on certain browsers (I think in Safari, at least), so we had to serve some file types without the header. Mistakenly, we also included image files in the exclusion, as everyone through image files couldn't contain scripts. But the MIME type for SVG files is
image/svg+xml... It was very embarrassing to have such a simple XSS vuln flagged in a security audit. -

That's already happening.
You can also change the main color of many SVGs (icons or even desktop backgrounds) with one simple edit, one command, one click.
In web sites, you can assign CSS classes to SVG graphics and thus e.g. change their color according to a theme.
That's my extent of fiddling with it.
IIRC they also use fonts the same way CSS/HTML does.
BTW, there are situations where an SVG is significantly larger than a corresponding raster image. It depends on the content.

Postscript is also literally just a text based programming language for drawing stuff. You can create loops and recursions and all kinds of crazy transformations with a few lines of code.

I'm not sure that lossy compression on vectors is strictly impossible.
You can do things like store less colour information and simplify splines so that curves are less complex.

One should always optimize assets for the web, this includes svg as well.
For critical paths I use https://optimize.svgomg.net/ a svg file optimizer. Svgs that are coming directly from illustrator or sketch are getting better these days but this little tool is invaluable regardless.
I think you can run this local too
