chrome zooming and chessboard dislocation when saved as pdf (chrome built-in)

"i don't understand what i'm talking about"

That makes two of us, and I suspect we're not alone.

@Doofenshmirtz

I invite you to look at the pictures. do you not understand that the check-board is not aligned with the pieces?
you didn't look? no very polite to jump of the partial quote without giving a hint of having tried. you did look? i hope you will find my next posts repeatable.

For my verbosity, well i'm stuck with this brain...sorry­. I do understand my experiments though, which you did not quote.

Invariance=robustness=objective of responsive design-in-theory, it all depends if responsive design is dev. speak for mobile only, or mobile first. I don't think this is the case here. I did not know lichess v1. i am not comparing.

I am just a fully ten-fingered human being, used to computer interfaces with lots of parallel choices available at a time, and a continuous input device, oh, and a real viewing surface where things can get done, also parallel, because there is some space left on it, even if playing lichess. And until my main OS goes completely mobile, i hope to keep using my computer that way. This is where i am coming from.

Also, i have had a hard time today, as my optimum settings kept shifting around. (is optimum ok with you?). I will standardize my pictures a bit and hope to make my experiments repeatable easily for any non-mobile computer user that is interested.

Apparently, not you. so, on to the next post. soon.

I feel we may arrive at some sort of conclusion sooner if perhaps there was less typing involved. It seems to me that you've made tens of posts on several topics here and received very few replies in return. It is just possible that I'm not the only one confused by what you're trying to do? Or perhaps there's another reason? But what?

Perhaps if you could write a very short (one or two sentences) description of what you're trying to do; what you would like or expect to see and what actually happens instead?

Note of Caution:
you might need to use a desktop computer to view my posts, otherwise, i feel your pain.

The point might get made not in your first view-port mobile screen. Watch out for your thumbs tendons.

If no choice, you can still look at a few posts that are brief here or there, with pictures through links.. do not despair.
look for links, there. explanations are in the links' file names. and if you have any questions about those filenames, here is a thread.

Today, i realized that i may have been using my preferred browsing window size that's a compromise between full-screen and using my desktop to do other things than browsing. So some vague mousy value in between the break-points.

one free column of desktop on right or left, saving urls on the desktop folder that i administer requires that in chrome, anyway (try to do that full-screen or mobile).

Top and bottom maxed. i will find a view-port measurement extension for that source of variation, too many possibilities.

So i decided to go full-screen to reduce the amount of parallel and continuous choices available to the desktop computer user (or laptop, 16:9) .

This makes the experience, i think, closer to mobile as you don't see anything else, it is all that exists right now, etc.... and the dimensions are taken from a restricted finite set, say 16:9 aspect ratio for all modern laptops, gaming monitors or TVs (diagonal size of monitor or TV may be another variable, but i will assume not). Hoping i am not the only lichess user in that statistical bin (cohort, as we keep going in time, i hope).

After full-screen, i will go back to my custom browsing windows size, but specify for the reader, interested user, and or dev, the windows size (apparent, view-port or else that matter), measured.

So next come a salvo of full-screen pictured experiments .

@Doofenshmirtz

Typing is not a problem as can you see. And if you are mobile only, anyways, this post does not concern you as a user.

But thanks for bringing me back to initial objectives, your intent. Sorry for previous post, added before aware of your antecedent one. It was not a reply.

Initial objectives:

First i had to make clear (maybe because of the silence) that the problem was not because i was stretching the limits, hence the default settings dislocated and distorted pictures.

So either the devs listen, and something is tried on that front. or not and i give my own solution, while the problems persists.

Second, and even initially, i had found a custom solution, in pdf previewing settings, but one had to be careful of some critical values where things break down, not continuously and close to that solution:

1. A3, Landscape, margins as default but for lower one at 2.03. but

2. Break value just near by, 2.04, i.e. you may miss it with a touch screen computer, but not a careful mouse input.

I left the thread sitting with pictures available, well named, i thought. if a user was in need of pdf keeping, they at least had some temp sol.

But i kept playing, trying other formats, as some info got hard to read sometimes. The A3 break points, and resulting particular elements relative dispositions made the page breaks, literally break some elements that were chosen to be there.

Many joyous experiments (i actually enjoy this) later:

I found that A4, landscape with 3 custom margins had wider move list display in the pdf, than the A3 i proposed, first.

And then today, it seems that lichess (or someone in) has listened, because of all the default landscape formats, only A3, was right on the spot, no need to customize. fluke? works in fullscreen, and i need to check back in my preferred window size.

But, my old optimal value for A3, landscape, lower margin of 2.03, and the close breakpoint had consequently shifted.

Also, the other format custom solutions, have shifted today, and if i don't hallucinate, during the day.

Fullscreen to eliminate the possibility that today's fluctuations were not flukes, due to my particular browsing window size.

Also i might use view-port or windows measuring extension for more user chosen settings for the browsing window.

i will repeat those fullscreen experiments from time to time.

Keep reading, looking at the pictures, and possibly try it yourself, or not.

PS: this might be more of a blog, but i don't care for labels, or titles. can it sit here? all that matters now. i like the question and answer format, even if i am the only one doing both most of the time. that's no blog, really? Are my questions clear?
i Repeat:
pdf previewing bug at default settings for all page formats (a dent in that info today)?,
mousy solution exists, but where exactly? how not to find it, not miss it.
keep a tab on those, with time.

1. pdf previewing bug at default settings for all page formats?, for the devs

   while 1) is considered:

2. mousy solution exists, but where exactly? how to find it, not miss it. for the users

3. keep a tab on 1) and 2), with time. for both audience.

if lichess considers the desktop users ability to keep pdf records is worth it,
then
expect the devs to consider fixing the bug.
if not
i expect lichess dev(s) to let us know, so that my custom work-around become sharable.

I do have also the lurking more philosophical question, that follows my practical questions above: Is lichess going mobile only? i.e. leaving desktop computer extra possibilities? But i hope that the dev solution is not that hard to find, and such decision be left for later. i still worry about the mobile-only mindset becoming the only way. but that should be for another thread or forum. It is just hard to forget. The positive spin i hope for: responsive design really exists, and here we go improving it, this thread being an example, at the end, when it is solved by lichess.

So thanks @Doofenshmirtz for helping me restrain my vocab. lots of self-editing, very time consuming on my end, but hopefully i did succeed. still verbose.... just less.

And remember, i really like lichess, why would i spend so much time here? I even enjoy the minimalism that the mobile objective brought, but don't throw the baby with the bathwater...

can i go do my pictures now?

wat

wat wat? oh the bathwater stuff, i guess it is a french saying, not to go overboard when fixing something, like you did not see the baby in the bathwater, it must come from old times, when you had to throw the bathwater...

quickest temp-fix: go fullscreen, even from the pdf preview, then choose landscape and A3. the only setting that does not need tweaking. All else is broken.

i do have data from my experiments that might give some clue to the dev as to which parameter does not go through as planned in pdf preview. the breaks don't change with browser windows size below fullscreen, but the margin settings temp fixes do so in continuous dependence, i was unlucky with A3 temp-fix being so close to a break value. by breakpoints, i mean those margin settings that trigger a shuffling of lichess elements.

For those not satisfied with the A3 lanscape temp-fix, because of where the page break might happen, or the width of the move list. there is an A4 landscape margin temp-fix, that i like now. later though, i need to play some chess, the timers are calling me.

Correction and precisions:

i was wrongly assuming the margin breakpoints were about reshuffling the elements, perhaps it is somewhere, but the disposition of the few elements in my analysis page previewing experiments, do not seem to change relative to each other, only they may get on one side of the page break, in the middle of it, or the other side, but that's not the critical values i call breakpoints.

values above or below which, the distorsion becomes dislocation (or distortion undergoes a discontinuity). easy to understand while looking at the pictures, up there in a previous post. look for 2.03 and 2.04 lower margin.

I forgot to mention, all my experiments, past and future.
lichess zoom at 50%
chrome zoom at 100%

Good news from the user perspective, and questions to the dev-like reader.

I'm continuing my bottoms-up research effort, starting from the user perspective trying to learn (only?) whats needed from under the hood to satisfy solution and or curiosity.

The following series of posts is organised as follow:

A) For the user:

1) Good news for the non-mobile usage (not users, drivers can also be pedestrians, different pace)

a) Pages with no pdf printing distorsion exist. (1 post)

b) For those pages, suggestion of practical page formats with respect to page break location. (1 post)

c) Pages with distorsion/dislocation: (1 post)
Full-screen experiments. clarifying the extent of problem.
Temps fixes settings, values and how to.

B) Questions for the Dev(s) or dev-like reader, stemming from this bottoms-up learning effort.

1) Narrowing down to the html piece position code: mini-board vs interactive board.
2) Suggestion of direction for my continuing research/learning effort (CSS mods?).
3) My current understanding/hypothesis to the nature of the problem here. Feedback invited.
(pdf distorsions and CSS grid vs pdf grid, same problem?)

C) New front opened: Mobile pdf saving/printing to file (to and through the cloud, cloudy) (1 post). Emulated mobile.

NB: Please wait until all these posts are posted, otherwise i might get lost, and that's bad for verbosity. It is all ready to be self-edited, i just need to stop somewhere, and be constrained by this post. let's see if that works.

PS: where are all my tabs gone, the input window sees them, the output, not. sorry for indentation not there
