CSS 3 not selector for print media - css

I am trying to print a part of my entire html document. I am using the below css to do that.
#media print { body * {
visibility: hidden;
}
#print-area * {
visibility: visible;
}}
It is working but as visibility:hidden reserves the space, it is printing a blank page and my content. I was trying to use :not selector from css3 to set all other divs but "print-area" to display:none as below,
div:not(#print-area){ display:none; }
This will result into a print of blank page. Looks like :not selector is not working with media print. Any suggestions/solutions for this will be most welcome.
Thanks

visibility: hidden; holds the space and it is hidden only. Show use display: none; to your body.
#media print { #wrapper {
visibility/: hidden;
display: none;
}
#print-area {
visibility/: visible;
display: block;
}}
Edit you should also declare for screen
#media screen { #wrapper {
display: block;
}

use this :
:not(#print-area){ display:none; }

Change the style rule for print media to be
:not(#print-area){ display:none !important; }
It's likely that any standard css reset in play on the page is outranking this style rule.

Hide a navigation element while on desktop, show it only mobile

On my page (test online at visal.de/trb/) I currently try to hide one element and show another when the user is on mobile. The blocked element is the top navigation (Glossar & FAQ and Intern), the element I only want to show to mobile users is the element "Weiterführendes".
I tried nearly everything, like this media query:
/* topfix */ #media (max-width: 479px) {
#header nav ul.hide-top, #header .hide-top {
display: block;
visibility: hidden;
}} #media (max-width: 600px) {
/* Header */
#header nav ul.hide-top li {
display: none;
visibility: hidden;
}
#header nav ul.hide-top li .phone {
display: block;
visibility: hidden;
}
but nothing really seems to work. I guess because the code more than once says that it should be displayed whenever, but in the end say that it shouldnt be shown. Possibly this is what occuring the errors. Anyone knowing a fix or what I did wrong?
A media query with max-width tells the browser to apply the styles when the browser shrinks to that size. Min-width is the opposite. It tells to browser to apply the styles when the browser grows to that size.
In the second media query you listed, which is the first one that will activate when shrinking your browser, you're telling it to display: none which will hide the element and will remove the space it occupies. You're also setting visibility: hidden which will only hide the element but not remove the space it occupies. Using visibility here is redundant.
In the first media query, which is the second one that will activate when shrinking your browser, you're telling it to display: block which will undo the previous display: none, but you're still also setting the visibility: hidden, rather than switching it to visibility: visible, so the element still won't display.
Here's a simple example of a mobile-first approach, rather than desktop-first like your example, to show / hide a class.
.my-mobile-image {
display: none; /* This is how it looks on mobile */
}
#media (min-width: 600px) {
.my-mobile-image {
display: block; /* This is how it looks on desktop */
}
}
you are not using the media queries in the right way . you should describe the min and max lenght of the screen
for mobile screen
#media screen and (min-width:299px) and (max-width:479px) {
display: block;
visibility: hidden;
}
other screen resolution
#media screen and (min-width:480px) and (max-width:600px) {
/* Header */
#header nav ul.hide-top li {
display: none;
visibility: hidden;
}
#header nav ul.hide-top li .phone {
display: block;
visibility: hidden;
}
}
i hope it will work can't test it right now at the moment

How to override "::-webkit-scrollbar" CSS rule and make scrollbar visible again

I use the following rule to make scrollbars invisible:
::-webkit-scrollbar { display: none; }
How do I override this rule to make scrollbars visible again? I tried the following:
::-webkit-scrollbar { display: initial; }
In this case scrollbars reserve their space, but the thumb is not visible.
See a short demo here.
try
::-webkit-scrollbar { visibility: hidden; }
and
::-webkit-scrollbar { visibility: visible; }
Edit:
Though, that would keep the space... So, add "width: 0 !important;"

Media Query Styles Not Overriding Original Styles

I'm attempting to use some media queries for a website I'm building. The problem I'm having however, is while the media query styles are actually being applied, they're being overridden. I can't for the life of me tell why because I'm using the same exact selectors. Can anyone point out something that I'm not seeing?
ORIGINAL CSS
#global-wrapper-outer > #global-wrapper-inner {
width: 85%;
height: 100%;
margin: 0 auto;
position: relative;
}
#global-wrapper-outer > #global-wrapper-inner > nav {
background: #fff;
padding-bottom: 20px;
box-shadow: 0 4px 2px -2px gray;
}
MEDIA QUERY CSS
#media screen and (max-width:1024px) {
#global-wrapper-outer > #global-wrapper-inner {
width: 100%;
}
#global-wrapper-outer > #global-wrapper-inner > nav {
display: none;
}
}
The second media query is working fine, where I set the nav to have a display of none. However, when I try to set the width of #global-wrapper-inner to 100% it doesn't apply. I can see the style being "applied" when I press F12 and select that element. However, the style itself is crossed out and not actually applied and it still has the original width of 85%.
The selectors in your original CSS have the same specificity as the selectors within your media queries (the first declarations are also targeting the same property - width) and because the media query rule set is being overridden I'm going to assume that it appears before the original rule set.
The second media query selector works because it's targeting a property that wasn't set in your original CSS, so specificity isn't relevant.
To have the first media query selector take precedence, prepend an ancestor element to it:
#media screen and (max-width:1024px) {
body #global-wrapper-outer > #global-wrapper-inner {
width: 100%;
}
#global-wrapper-outer > #global-wrapper-inner > nav {
display: none;
}
}
You need to link the media query file (queries.css) later than the normal css file (style.css). That way the rules in the queries.css will override those in style.css.
I have been at least 2 hours trying to find the override CSS problem till I found that my line comments where wrong... And the second definition of CSS wasn't working:
So, don't be so stupid as I !:
/* LITTLE SCREENS */
#media screen and (max-width: 990px) {
... whatever ...
}
/* BIG SCREENS */
#media screen and (min-width: 990px) {
... whatever more ...
}
never use: Double bar as I did:
// This is not a comment in CSS!
/* This is a comment in CSS! */
Here is the answer. (at least what worked for me)
I've had this problem before, and it took me a while to realize what I did, but once I figured it out it's actually pretty easy.
Ok so imagine I have this as the html
<main>
<div class = "child1"> </div>
<div class = "child2"> </div>
</main>
and then this as the CSS
main .child1{
height: 50px;
}
/* now let's try to use media quaries */
#media only screen and (max-width: 768px) {
.child1{
width: 75%;
}
}
The code above won't affect the .child. Just like someone mentioned above, the main .child1 overrides .child1. So the way you make it work is to select the element just like we did at the very beginning of the CSS above.
/* this will work */
#media only screen and (max-width: 768px) {
main .child1{
width: 75%;
}
}
So as a conclusion... select the elements the same way every time.
Meaning ... for example in the above code, in your CSS, you should either select it as main .child1throughout the whole CSS or .child1 or else they get mixed up, one ends up overriding the other.
From the code you submitted, this probably won't resolve your issue. However, in your CSS if you are nesting styles inside of one another:
.main-container {
.main {
background: blue;
}
}
A media query for .main won't work because of the nesting. Take .main out of .main-container and then the media query will work as assumed:
.main-container {
}
.main {
background: blue;
}
Check if your media query braces are equal.
Sometimes it is very subtle but when you miss a single brace the rest of the media queries mentioned for certain break points will not work
example:
#media(min-width: 768px) and (max-width: 991px){
#media (max-width: 767px){
.navbar-brand p {
font-size: .6em;
margin-top: 12px;}
.navbar-brand img {height: 20px;}
#collapsable-nav a {
font-size: 1.2em;
}
#collapsable-nav a span {
font-size: 1.2em;}
}
Here you can see i have started the braces for max-width:991px but forgot to end so the next set of codes in media query for max-width:767px will not work.
It is a very simple mistake but took hours because of lot of braces in the codes.
Hope it helps. Happy Coding!
What about using !important? If you range your media query from ( min-width: 176px ) and ( max-width: 736px ) or even up to 980px?
There can be some reasons because of which this type of error may occur.
I myself faced this issue where I was not able to understand what I am needed to do and was confused that, does media query just overrides the elements.
Here's what I understood:
MEDIA QUERY CSS:
#media screen and (max-width:1024px) {
#global-wrapper-outer > #global-wrapper-inner {
width: 100%;
}
#global-wrapper-outer > #global-wrapper-inner > nav {
display: none;
}
}
here you were able to override #global-wrapper-inner > nav i.e., 2nd media query selector, by display: none;
because you never added the display line in the original css, because of which there was nothing to override you just have given that display type should be none.
Whereas just in the 1st media query selector you already had given width:80%;
Basically media query doesn't override as far as I have understood but it take precedence, like already explained by one of them
by which media query comes to work:

then this might help.

How to only show certain parts with CSS for Print?

I have a page with lots of data, tables and content.
I want to make a print version that will only display very few selected things.
Instead of writing another page just for printing, I was reading about CSS's feature for "#media print".
First, what browsers support it? Since this is an internal feature, it's OK if only the latest browsers support it.
I was thinking of tagging a few DOM elements with a "printable" class, and basically apply "display:none" to everything except those elements with the "printable" class.
Is that doable?
How do I achieve this?
EDIT:
This is what I have so far:
<style type="text/css">
#media print {
* {display:none;}
.printable, .printable > * {display:block;}
}
</style>
But it hides everything. How do I make those "printable" elements visible?
EDIT:
Trying now the negative approach
<style type="text/css">
#media print {
body *:not(.printable *) {display:none;}
}
</style>
This looks good in theory, however it doesn't work. Maybe "not" doesn't support advanced css ...
Start here. But basically what you are thinking is the correct approach.
Thanks, Now my question is actually
becoming: How do I apply CSS to a
class AND ALL OF ITS DESCENDANT
ELEMENTS? So that I can apply
"display:block" to whatever is in the
"printable" zones.
If an element is set to display:none; all its children will be hidden as well. But in any case. If you want a style to apply to all children of something else, you do the following:
.printable * {
display: block;
}
That would apply the style to all children of the "printable" zone.
If you want to display some links etc. when in the browser, that you don't want to be printed. Furthermore you have some logos and letterhead info that only should go on the printed page.
This seems to work fine:
Example:
CSS:
#media print {
.noPrint {
display:none;
}
}
#media screen {
.onlyPrint {
display: none;
}
}
HTML:
<div class="noPrint" id="this_is_not_printed" >
<a href=links.html>
</div>
<div class="onlyPrint" id="this_is_only_seen_on_printer" >
<img scr=logo.png >
<img scr=letterhead.png >
</div>
A simple way:
<style>
.print-only{
display: none;
}
#media print {
.no-print {
display: none;
}
.print-only{
display: block;
}
}
</style>
I got here because I was curious about printing a chart generated by chart.js. I wanted to just print the chart directly from the page (with a button that does a 'window.print') without all of the other content of the page.
So, I got closer by using the technique from the answer here: Why can't I override display property applied via an asterisk? .
You have to apply the 'asterisk' to the 'body' element, not just by itself. So, using the example CSS that the OP (Nathan) added to the question, I changed it to this:
<style type="text/css">
#media print {
body * {display:none;}
.printable, .printable > * {
display: block !important;
}
}
</style>
Then adding that 'printable' class to the chart itself, as in
<canvas id="myChart" class="printable" width="400" height="400"></canvas>
Which removed all page elements on the printed output except the chart when the 'print' button is clicked (via this):
<script>
myChart.render();
document.getElementById("printChart").addEventListener("click",function(){
window.print();
});
</script>
So, perhaps this will help anyone that gets to this question via the googles.
Came across the same question recently and for me, this solution works just perfect:
#media print {
* {
visibility: hidden;
}
.printable {
visibility: visible;
position: absolute;
top: 0;
left: 0;
padding: 10mm;
}
.printable * {
visibility: visible;
}
}
Since visibility: hidden doesn't remove elements, as display: none does, it is possible to change it for desired elements separately.
Nearly all browsers support it. It might be advantageous to use the media attribute on the link tag.
Using display: none; in some of your rules would be an appropriate way to handle your situation.
I suggest to hide the element that you won't print:
HTML
<h1 class="no-print" >Welcome Just Screen</h1>
<div> I want print this section :)</div>
<div class="no-print">It's display only on screen</div>
CSS
#media print {
.no-print {
display: none;
}
}

Hide all elements except one div for print view

I have the following CSS for my print style:
* {
display:none;
}
#printableArea {
display:block;
}
I expected this to hide all elements, and only show the printableArea, however everything gets hidden. In print view, all I get is a blank page.
I have it included properly in the HEAD, with media="print" on this particular stylesheet.
If an element is not displayed, then none of its children will be displayed (no matter what their display property is set to).
* matches the <html> element, so the entire document is hidden.
You need to be more selective about what you hide.
You're taking the right general approach, but you want to use visibility: hidden instead of display: none so that you can set child elements to be visible.
See Print <div id=printarea></div> only?
html body * {
display:none;
}
#printableArea {
display:block;
}
Also, you may need an !important on #printableArea, but probably not.
Answering because I found this question while searching for this
Instead of 'display: none' you can use :
* {
visibility: hidden;
margin:0; padding:0;
}
#printableArea * {
visibility: visible;
}
source : https://www.concrete5.org/community/forums/5-7-discussion/need-to-print-a-certain-div-and-ignore-everythign-else-on-the-pa
You might try popping it up on top of everything. This solved 90% of my problems, then I just had to make a .noprint class and add it to a few straggling elements.
.print_area{
position: fixed;
top: 0px;
left: 0px;
width: 100%;
z-index: 9999;
background-color: #ffffff;
}
If you want to use JavaScript, you can try this simple snippet that doesn't even require jQuery:
document.body.innerHTML=document.getElementById('printableArea').innerHTML;
make a div wrap everything after the body tag. Before the wrap div, put the visible item's div.
I had to do this to make a simple username-password page, and needed to hide everything, except the half-opaque sign-in form's background. So, after the correct credentials were typed in, the form would animate out, and the half-opaque page cover would animate out, and finally, EVERYTHING aside would show up and you could use the page normally.
There is a one-line solution:
With JQuery
var selector = '';
$(document.head).append($('style').text('*{visibility:hidden}' + selector + '{visibility:visible}'));
Without JQuery
var selector = '';
document.head.appendChild(Object.assign(document.createElement('style'), { innerText: '*{visibility:hidden}' + selector + '{visibility:visible}' });
In both examples, set the selector variable to the selector you want. For example, div#page:hover or p.class1,p.class2
#media print {
* {
visibility: hidden;
}
/* Show element to print, and any children he has. */
.svgContainer, .svgContainer * {
visibility: initial;
}
}
Make sure any children elements are also visible. Remember that invisible elements still influence positionning of other elements in the page. In my (simple) case, I just added position: fixed; on .svgContainer (somewhere else).
Simply you can use the following code and assign "hide" class to that specific element you dont want to display on print page
<style type="text/css" media="print">
img
{
display:none;
}
.hide
{
display:none;
}
</style>
There is another clean way to achieve this:
* {
visibility: hidden;
}
#printableArea {
visibility: visible;
position: absolute;
top: 0;
left: 0;
width: 100%;
}
That way you're going to get only the #printableArea element in the print view and all of the other elements will be hidden.
