I'm working on a ElectronJS and Reactjs project to build an application that prints documents (as web HTML format) using thermal printers.
Thermal printers prints documents on special papers with 50mm or 80 mm of width but it has no limits of height.
I use Reactjs to generate HTML Contents and CSS3 print media style to hide screen contents #root and show only what i want to print #print,
#media only print {
#page {
size: auto; /* auto is the initial value */
margin: 0; /* this affects the margin in the printer settings */
height: auto !important;
width: 70mm !important;
}
html, body {
margin: 0 !important;
padding: 0 !important;
position: fixed;
left: 0;
top: 0;
background: #eee !important;
font-family: 'Tahoma', 'Segoe UI Light', 'Segoe UI', 'Helvetica Neue Light', 'Helvetica Neue', Helvetica, Verdana, sans-serif !important;
visibility: hidden;
height: auto !important;
width: 70mm !important;
overflow: visible !important;
}
#root {
display: none !important;
visibility: hidden !important;
}
#print {
display: block;
position: fixed;
left: 0;
top: 0;
visibility: initial !important;
padding: 1px !important;
background: white;
border: none;
outline: none;
margin-left: 5mm;
height: auto !important;
width: 70mm !important;
overflow: visible !important;
}
}
The problem is when i try to print long pages, it print only the upper part of it. I figure out that it is related somehow with the screen height. Because it print the exact same part that appear when i show the print scope and it ignore the scrollable part of the document.
webContents.print({ silent: true, printBackground: false, printerName },() => {});
I think my issue is very close to this one.
Any idea will be helpful,
I fixed it.
I just remove position: fixed; from both html, body and #print.

So, I am trying to create a draggable list with React-Motion in my project.
However, I couldn't figure out a way to remove the spaces between the list (see the picture below). I read somewhere that it is due to the nature of absolute elements in HTML.
// Here is a snippet of the CSS styles
// View the entire codes by clicking the link below
.demo8-item {
position: absolute;
width: 320px;
height: 40px;
overflow: visible;
pointer-events: auto;
transform-origin: 50% 50% 0px;
border-radius: 4px;
color: rgb(153, 153, 153);
line-height: 40px;
padding-left: 32px;
font-size: 24px;
font-weight: 400;
background-color: rgb(255, 255, 255);
box-sizing: border-box;
-webkit-box-sizing: border-box;
}
.demo8-outer {
width: 100%;
height: 100%;
display: flex;
justify-content: center;
align-items: center;
display: -webkit-flex;
-webkit-justify-content: center;
-webkit-align-items: center;
}
I have tried to inspect the HTML elements to find the culprit, but to no avail. I couldn't find the element that is causing those spaces; setting margin and padding to 0 doesn't do anything!
My question is, is there a way to remove those spaces without breaking the animation (i.e. by converting it to inline-block, etc.)?
Thank You.

You can control the height used by spring() configurations
// `y` prop, here is how the height is calculated
y: spring(order.indexOf(i) * 100, springConfig),
Change 100 to something like 70 or whatever you like:
y: spring(order.indexOf(i) * 70, springConfig),
So this is my problem, I am trying to print some components in React using window.print, my components have defined sizes say 5cm x 5cm, I have hidden all other components in the print page (note that the styling of the whole page is somehow complex to post here), the problem is that my components get resized when on the print page. I have looked a lot but nothing has worked for me.
Note that when I tested the same print in a different page (with no complex styling) it worked fine. So is there any way to pass the styles to the print window or "Override" the styling so that my components get rendered correctly?
Thanks.
EDIT: Here is my CSS. This is working fine in a fresh app so there must be something I used messing things up, I removed all #media print from Bootstrap CSS files but no luck.
I tried to put the code inside as well as outside the #media print but no luck as well.
As far as I know media should render real physical lengths and units, any help would be appreciated.
Thanks again

Recently, I've encountered with the same issue while designing a print template in React. I was totally wrong in my understanding that whatever styles I write in my CSS files will apply. Then I found there is certain semantics while are required to be followed while designing an HTML print template.
Take a look at this link. This will be very helpful for your design.

We are experiencing problems with a form and its parent div. We tried to bring in a frosted glas style to the parent div landingboxForm, but if we are working with pseudoelements, nothing happens.
The tutorial is from here https://medium.com/#AmJustSam/how-to-do-css-only-frosted-glass-effect-e2666bafab91 and is working well for others. I just do not succeed in port it for our landing page.
Does anybody know why the :before div tag is just grey in the Chrome inspector and why it does not appear?
CSS:
.lp-sorba {
background-size: cover;
position: absolute;
width: 100%;
top: 0;
left: 0;
bottom: 0;
height: 900px !important;
}
.lp-sorba .landingpageHeader {
height: 80px;
background: #1d89d2;
}
.lp-sorba #hs-link-logo > img {
margin-top: 22px;
}
.lp-sorba .landingboxForm:before {
content:" ";
background: inherit;
left: 0;
right: 0;
top: 0;
height: 100%;
width: 100%;
bottom: 0;
box-shadow: inset 0 0 0 3000px rgba(255,255,255,0.3);
filter: blur(10px) !important;
}
.lp-sorba .landingboxForm {
background: inherit;
width: 100%;
height: 100%;
position: relative;
border-radius: 5px;
box-shadow: 0 23px 40px rgba(0,0,0,0.2);
padding: 20px;
border: 0.5px solid #edebeb;
}
As for your question
why the :before div tag is just grey in the Chrome inspector and why it does not appear?
Your pseudo element is collapsing right know. Add position: absolute; to the .lp-sorba .landingboxForm:before rule.
But that won't solve your underlying problem / won't create the frosted glass effect.
The way how filters work is: they get applied to the element itself only, not the ones lying behind it.
In the example from Medium/Codepen, the form element inherits the background from the main element. By that it's pseudo element may apply a filter to it.
In your setup, the form is positioned absolute, while the image tag is also positioned absolute. The forms filter won't bleed into that image tag.
Revisit the example:
apply a background image to a parent container
inherit that in the form
pseudo filter on the form will blur the forms inherited background
I have a table with a lot of columns and a horizontal scrollbar. I'm searshing a way to show it in fullscreen, like you can do in gmail when you want to see an mail attachement with a glyphicon-resize-full
If someone have an idea :)
edit : I'm trying with this :
<div id="overlayContainer" class="overlay">
<div id="overlayContent" class="overlay-content">
</div>
using a css to have a bigger table on a black background
<style>
.overlay {
height: 0;
width: 0;
position: fixed;
z-index: 1;
top: 0;
left: 0;
background-color: rgb(0,0,0);
background-color: rgba(0,0,0, 0.9);
overflow-x: hidden;
transition: 0.5s;
}
.overlay-content {
position: relative;
top: 25%;
width: 100%;
text-align: center;
margin-top: 30px;
}
.overlay a {
padding: 8px;
text-decoration: none;
font-size: 36px;
color: #818181;
display: block;
transition: 0.3s;
}
.overlay a:hover, .overlay a:focus {
color: #f1f1f1;
}
.overlay .closebtn {
position: absolute;
top: 20px;
right: 45px;
font-size: 60px;
}
#media screen and (max-height: 450px) {
.overlay a {
font-size: 20px;
}
.overlay .closebtn {
font-size: 40px;
top: 15px;
right: 35px;
}
}
and I fill the div overlayContent or close it by this way :
$scope.fullScreenElement = function () {
document.getElementById("overlayContainer").style.height = "100%";
document.getElementById("overlayContainer").style.width = "100%";
document.getElementById("overlayContent").innerHTML = document.getElementById("tableContent").innerHTML;
};
$scope.reduceElement = function () {
document.getElementById("overlayContainer").style.height = "0%";
document.getElementById("overlayContainer").style.width = "0%";
};
But with that I can't use JS functions of my table :(
edit : Here is an example : http://plnkr.co/edit/1ge8r8zFANDNt2P2k0kI?p=preview
I couldn't reproduce it, but table should have horizontal scrollbar and you should't see lasts columns at the right. And if you expand it, you see the entire table but javascript like click on column name to sort (it's not in my Plunker) doesn't work
edit : I tried a second time with your angular.element(document.getElementById($scope.id)).addClass("overflowFullScreen");
Nimmi, and it's better than my first try, it keeps JS functions. I continue with this, but looks good. Thank you !
final edit : I resolves lasts problems caused by z-index and a missing vertical scrollbar but it is done ! Thank you for your help !
I have a problem with a CSS grid I built. The relevant site is this: http://dr-brauchle.de/
The wall of photos underneath the content is constructed with a grid of floated boxes. This works fine as long as all the boxes have fixed width and height values.
To make the site responsive I use percentages on the width of the boxes and "auto" on their height and the same applies to the images that are loaded into these boxes. The media query jumps in at 1199px and converts the static box sizes to fluid box sizes.
This produces problems at certain resolutions where the second large image box jumps from the left margin of the page to the right and thus destroys the order of the grid. Making the browser window bigger makes the box jump in to place again. This is very annoying since the resolution on an iPad 3 for example produces this error as well.
On the boxes (sse code below) I had to use a "line-height: 0" to eliminate gaps of a few pixel between the boxes. This seems to be part of the strange float-problem.
.box-1 {
width: 25% !important;
height: auto;
display: block;
overflow: hidden;
float: left;
background-size: cover !important;
line-height: 0;
}
.box-2 {
width: 50% !important;
height: auto;
display: block;
overflow: hidden;
float: left;
background-size: cover !important;
line-height: 0;
}
Thanks a lot for ANY help!

So what I found is that you need to force an aspect ratio.
Try modifying the following styles:
.box-1 {
width: 25% !important;
height: 0;
display: block;
overflow: hidden;
float: left;
background-size: cover !important;
line-height: 0;
position: relative;
padding: 13.75% 0 0 0;
}
.box-1 img {
width: 100% !important;
height: auto !important;
position: absolute;
display: block;
max-width: 100%;
max-height: 100%;
left: 0;
right: 0;
top: 0;
bottom: 0;
margin: auto;
}
Basically the modification above set up the box-1 to have a fixed aspect ratio then positionsw the img in in absolutely. To calculate the 13.75%, I took one of your images and got 165/300=.55 --> .55*.25=.1375 --> 13.75%
Hope this solves your issue.
