It might be a stupid question or even worse. However, I've seen around the web many layouts with the following text "Lorem ipsum dolor sit amet".
What is Lorem Ipsum?
Is it a standard? Or a good practice in the frontend world?
Where does it come from?
Why do we use it?
Its meaningless (Latin) but used as demonstrative text to show how a layout might look.
https://en.wikipedia.org/wiki/Lorem_ipsum
In publishing and graphic design, Lorem ipsum is a placeholder text
commonly used to demonstrate the visual form of a document or a
typeface without relying on meaningful content. Lorem ipsum may be
used before final copy is available, but it may also be used to
temporarily replace copy in a process called greeking, which allows
designers to consider form without the meaning of the text influencing
the design.
Lorem ipsum is typically a corrupted version of De finibus bonorum et
malorum, a first-century BC text by the Roman statesman and
philosopher Cicero, with words altered, added, and removed to make it
nonsensical, improper Latin.
Versions of the Lorem ipsum text have been used in typesetting at
least since the 1960s, when it was popularized by advertisements for
Letraset transfer sheets. Lorem ipsum was introduced to the digital
world in the mid-1980s when Aldus employed it in graphic and
word-processing templates for its desktop publishing program
PageMaker. Other popular word processors including Pages and Microsoft
Word have since adopted Lorem ipsum as well.

I have the following code inside Svelte REPL:
https://svelte.dev/repl/b96c96bb3a654f5a81813525d22a8820?version=3.29.0
There's a problem: the chessboard doesn't appear, or at a better case (without onMount) flashes while appearing, and then disappears...
What's wrong in this code and how to fix that ?
I think the problem for you is coming from how you're attempting to push cells to defs. When you replace defs.push(cells) on line 36 with defs = [...defs, cells] it allows the columns and rows to be created properly. Then for some reason you're setting xmlns through a variable... this is the main thing preventing anything from showing up. There is no reason to use a variable to set xmlns, pretty sure it's preventing the SVG from being created properly when done this way and you don't actually need xmlns for inline SVGs, so you can trash that and all works well as shown here.
However, unless you're planning on using the empty space inside the 1000 x 1000 SVG area then I'd advise you to cut it down to 800 x 800 so the squares fit into the overall dimensions better.
I use Chrome, (Version 63.0.3239.84 (Official Build) (64-bit)), and lately I have been getting what I believe are math rendering errors like this:
What do I to remedy this? Thanks!
The source code probably reads $7.95 for equity trades and $1.... MathJax renders the data between the dollar signs.
I believe that you can display a literal dollar by putting it in a span element (<span>$</span>).
I am evaluating the use of SVG for a website I'm working on, and I'd like to see some examples of pages using it effectively. I don't mean a "Sample SVG page" or specific parts like showing chars, but any well done site (not specifically about SVG) that conveys a good graphics experience through the employment of SVG for some or all of its graphics, as an alternative to styling it with PNG/GIF etc.
This question isn't really about programming, so is likely to get closed. Anyway here are a couple of examples:

Is there a command line tool on linux that would extract figures from a pdf file, and save them in vector format? I know about pdfimages, but that would create a bitmap, and that is not what I need.
not for images only, as you seem to need, but
pdftocairo
http://poppler.freedesktop.org/
http://www.manpagez.com/man/1/pdftocairo/ (manpage)
is able to render a pdf page to other vector formats like PS/EPS/SVG
assuming you have a pdf page with vectorized images, you can render this page to svg and then copy only image you are interested in
note: pdftocairo cannot render multipage pdf to multipage svg
if you need to convert to svg several pdf pages you need first to pick this page range and then burst pdf pages into single pdf pages
example (if we need to convert pages 1-10 of a pdf file to svg)
1°
pdftk file.pdf cat 1-10 output 1-10.pdf
2°
pdftk 1-10.pdf burst
3°
for f in *.pdf; do pdftocairo -svg $f; done
4°
finally, with sodipodi or inkscape, you can extract images you are interested from svg rendered pdf page
What do you consider a "figure"? This is a concept that doesn't exist in PDF. The reason there are so many tools that can extract images from a PDF file, is because images are a very clearly identified entity.
Your "figures" however, are much less clearly defined. PDF files may contain lots of vector content that you wouldn't call a figure. Text can be stroked for example, which would make it vector art and as such it might be confused with your figures. Other decorative elements may be used in the background of the pages. Text may be underlined, which would be a vector element...
In the other direction, your "figure" may contain a caption that is text, further complicating things.
As PDF doesn't have the notion of a figure, you'll have to figure out how to isolate one on a PDF page (perhaps because the creator application always adds metadata to them, or because they use a special color or... If you can isolate them, it should be possible to trim everything irrelevant on the page and export what you need as EPS or SVG using some of the techniques described in the other answer.
This article describes the tools gpdfx, inkscape and pdf2svg which are not completely commandline-based, but still sound helpful.

I have been using Photoshop for about three weeks now, finding it very different to fireworks...
Im trying to make a cool effect on my site, I want to use JQuery to slide a background image behind some text, and the background show through the text. I need to text to be placed in a white box, with the text itself "punched" out, so you can literally see through it (but only the text, the white box will cover everything else). The text also needs an inner shadow effect...just no fill. I am having real problems finding this info, can anyone help?
Many thanks, Dan
Create your white background layer
Create your text layer with the font and size you want
Ctrl+Click the text icon in the Layers panel to select the outline of your text
Select your white background layer and press delete to cut the text shape from your background
Select your text layer and delete it
Apply your drop shadow or glow filters to your background layer
Save as a transparent PNG-24
Your question doesn't sound too clear but i think animating the opacity of either of text or background would help.check this
