My PWA in a desktop browser is not really cool (because i don't have a lot of information to show).
And I would like to limit the width to 768px.
I tried many solutions, but i can't to change elements in position "fixed" like v-navigation, v-footer, v-dialog, ...
they are always 100% of the width of the browser.
I tried this in app.vue or in index.html:
html,body,#app {
max-width:768px !important;
overflow: hidden;
}
and last time I tried this in index.html:
#mytable {
width: 100%;
overflow: hidden;
}
#mytable td{
width:50%
}
<table id="mytable">
<tr>
<td>
<div id="app"></div>
</td>
<td>other half</td>
</tr>
</table>
But no solutions works.
Thanks for your help

Your problem seems you need different layout in function of screen size. You have several solutions from media queries to simple margin. Here I will explain how to do what you want with just margin.
I advise you to use a div to wrap your content and do not apply all your style in your #app container. Why ? Because you can imagine for instance that you want a top bar that take all the width and a content that take only 768px. If you make your layout in only one block this will be very complex. Separation in several block is a good strategy to have a modulabe UI. So we will use this template. You can make whatever you want in the .content div.
<div id="app">
<!-- Here we can imagine a top bar -->
<div class="content">
<!-- Display whatever you want -->
</div>
</div>
First you need to prepare your app container to display your application in all screen. I suggest this css :
html,body,#app {
overflow: hidden; // If content is large it will display scroll bar
height: 100vh; // Tell to your browser to take 100% of the available viewport height
}
Then you can define the css of the .content block :
.content {
max-width: 768px; // Max-width you want
height: 100%; // Take all the height available
margin: 0 auto; // Display div at the center
}
Here is an example: jsFiddle
If you are very interested in layout design, I strongly advise you to look into flex box and css grid.
<div id="abc">
<div id="bac" ngIf="show">
<!-- Content -->
</div>
<div id="cde">cds</div>
</div>
I have a div want to add or remove from DOM slowly(show and hide) using *ngIf and likewise adding or removing of div.id ="bac" should cause div.id='cde' to move left or right slowly like it is animating.
*ngIf probably is not he best thing you are looking for, instead of this, use ngClass and define the css transitions and positions for these animations.
*ngIf fully hides/shows a node from/in DOM, it's like display: none/block which is not able to be animated through css-transitions
here is an example
<div class="animated" [ngClass]=" { 'show': show, 'hide': !show }">
content
</div>
then in the css
.animated {
display: inline-block;
width: 100%;
height: 80px;
background: gray;
transition: 1.5s linear margin-left;
}
.animated.show {
margin-left: 0;
}
.animated.hide {
margin-left: -120vw;
}
Height also can be changed, depends on which effect you expect.
Here is stackblitz with working code
I am using bootstrap on my site and am having issues with the navbar fixed top. When I am just using the regular navbar, everything is fine. However, when i try to switch it to navbar fixed top, all the other content on the site shifts up like the navbar isn't there and the navbar overlaps it. here's basically how i laid it out:
.navbar.navbar-fixed-top
.navbar-inner
.container
.container
.row
//yield content
i tried to copy bootstraps examples exactly but still having this issue only when using navbar fixed top. what am I doing wrong?
Your answer is right in the docs:
Body padding required
The fixed navbar will overlay your other content, unless you add padding to the top of the <body>. Try out your own values or use our snippet below. Tip: By default, the navbar is 50px high.
body { padding-top: 70px; }
Make sure to include this after the core Bootstrap CSS.
and in the Bootstrap 4 docs...
Fixed navbars use position: fixed, meaning they’re pulled from the
normal flow of the DOM and may require custom CSS (e.g., padding-top
on the ) to prevent overlap with other elements.
As others have stated adding a padding-top to body works great.
But when you make the screen narrower (to cell phone widths) there is a gap between the navbar and the body. Also, a crowded navbar can wrap to a multi-line bar, overwriting some of the content again.
This solved these kinds of issues for me
body { padding-top: 40px; }
#media screen and (max-width: 768px) {
body { padding-top: 0px; }
}
This makes a 40px padding by default and 0px when under 768px width (which according to bootstrap's docs is the cell phone layout cutoff where the gap would be created)
a much more handy solution for your reference, it works perfect in all of my projects:
change your first line from
.navbar.navbar-fixed-top
to
.navbar.navbar-default.navbar-static-top
Just change fixed-top with sticky-top. this way you won't have to calculate the padding.
And it works!!
The solution for Bootstrap 4, it works perfect in all of my projects:
change your first line from
navbar-fixed-top
to
sticky-top
Bootstrap documentation reference
About time they did this right :D
#Ryan, you are right, hard-coding the height will make it work bad in case of custom navbars. This is the code I am using for BS 3.0.0 happily:
$(window).resize(function () {
$('body').css('padding-top', parseInt($('#main-navbar').css("height"))+10);
});
$(window).load(function () {
$('body').css('padding-top', parseInt($('#main-navbar').css("height"))+10);
});
This issue is known and there's a workaround in the twitter bootstrap site:
When you affix the navbar, remember to account for the hidden area
underneath. Add 40px or more of padding to the <body>. Be sure to add
this after the core Bootstrap CSS and before the optional responsive
CSS.
This worked for me:
body { padding-top: 40px; }
I put this before the yield container:
<div id="fix-for-navbar-fixed-top-spacing" style="height: 42px;"> </div>
I like this approach because it documents the hack needed to get it work, plus it also works for the mobile nav.
EDIT - this works much better:
#media (min-width: 980px) {
body {
padding-top: 60px;
padding-bottom: 42px;
}
}
As I've posted in a similar question, I've had good success with creating a dummy non-fixed nav bar right before my real fixed nav bar.
<nav class="navbar navbar-default"></nav> <!-- Dummy nav bar -->
<nav class="navbar navbar-default navbar-fixed-top"> <!-- Real nav bar -->
<!-- Nav bar details -->
</nav>
The spacing works out great on all screen sizes.
The problem is with navbar-fixed-top, which will overlay your content unless specify body-padding. No solution provided here works in 100% cases. The JQuery solution blink/shift the page after the page is loaded, which looks weird.
The real solution for me is not to use navbar-fixed-top, but navbar-static-top.
.navbar { margin-bottom:0px;} //for jumtron support, see http://stackoverflow.com/questions/23911242/gap-between-navbar-and-jumbotron
<nav class="navbar navbar-inverse navbar-static-top">
...
</nav>
All the previous solutions hard-code 40 pixels specifically into the html or CSS in one fashion or another. What if the navbar contains a different font-size or an image? What if I have a good reason not to mess with the body padding in the first place? I have been searching for a solution to this problem, and here is what I came up with:
$(document).ready(function(){
$('.contentwrap') .css({'margin-top': (($('.navbar-fixed-top').height()) + 1 )+'px'});
$(window).resize(function(){
$('.contentwrap') .css({'margin-top': (($('.navbar-fixed-top').height()) + 1 )+'px'});
});
You can move it up or down by adjusting the '1'. It seems to work for me regardless of the size of the content in the navbar, before and after resizing.
I am curious what others think about this: please share your thoughts. (It will be refactored as not to repeat, btw.) Besides using jQuery, are there any other reasons not to approach the problem this way? I've even got it working with a secondary navbar like this:
$('.contentwrap') .css({'margin-top': (($('.navbar-fixed-top').height())
+ $('.admin-nav').height() + 1 )+'px'});
PS: Above is on Bootstrap 2.3.2 - will it work in 3.x As long as the generic class names remain... in fact, it should work independent of bootstrap, right?
EDIT: Here is a complete jquery function that handles two stacked, responsive fixed navbars of dynamic size. It requires 3 html classes(or could use id's): user-top, admin-top, and contentwrap:
$(document).ready(function(){
$('.admin-top').css({'margin-top':($('.user-top').height()+0)+'px'});
$('.contentwrap') .css({'padding-top': (
$('.user-top').height()
+ $('.admin-top').height()
+ 0 )+'px'
});
$(window).resize(function(){
$('.admin-top').css({'margin-top':($('.user-top').height()+0)+'px'});
$('.contentwrap') .css({'padding-top': (
$('.user-top').height()
+ $('.admin-top').height()
+ 0 )+'px'
});
});
For handling wrapping lines in menu-bar, apply an id to the navbar, like this:
<div class="navbar navbar-default navbar-fixed-top" role="navigation" id="topnavbar">
and add this small script in the head after including the jquery, like this:
<script>
$(document).ready(function(){
$(document.body).css('padding-top', $('#topnavbar').height() + 10);
$(window).resize(function(){
$(document.body).css('padding-top', $('#topnavbar').height() + 10);
});
});
</script>
That way, the top-padding of the body gets automatically adjusted.
use this class inside nav tag
class="navbar navbar-expand-lg navbar-light bg-light sticky-top"
For bootstrap 4
for Bootstrap 3.+ , I'd use following CSS to fix navbar-fixed-top and the anchor jump overlapped issue based on
https://github.com/twbs/bootstrap/issues/1768
/* fix fixed-bar */
body { padding-top: 40px; }
#media screen and (max-width: 768px) {
body { padding-top: 40px; }
}
/* fix fixed-bar jumping to in-page anchor issue */
*[id]:before {
display: block;
content: " ";
margin-top: -75px;
height: 75px;
visibility: hidden;
}
All you have to do is
#media (min-width: 980px) { body { padding-top: 40px; } }
Further to Nick Bisby's answer, if you get this problem using HAML in rails and you have applied Roberto Barros' fix here:
I replaced the require in the "bootstrap_and_overrides.css" to:
=require twitter-bootstrap-static/bootstrap.css.erb
(See https://github.com/seyhunak/twitter-bootstrap-rails/issues/91)
... you need to put the body CSS before the require statement as follows:
#import "twitter/bootstrap/bootstrap";
body { padding-top: 40px; }
#import "twitter/bootstrap/responsive";
=require twitter-bootstrap-static/bootstrap.css.erb
If the require statement is before the body CSS, it will not take effect.
I would do this:
// add appropriate media query if required to target mobile nav only
.nav { overflow-y: hidden !important }
This should make sure the nav block doesn't stretch downpage and covers the page content.
This works and looks good for me.
<body class="pt-5 mt-4">....</body>
I just wrapped the navbar in a
<div width="100%">
<div class="nav-? ??">
...
</nav>
</div>
No fancy hocus pocus but it worked..
I'm using a CMS theme that contains all of Bootstrap 3. Is it possible to add a title block manually in HTML/CSS? I'm not sure if that's the block's official name... it's the purple full-width block containing the text:
CSS
Global CSS settings, fundamental HTML elements styled and enhanced with extensible classes, and an advanced grid system.
in the following link (for example):
http://getbootstrap.com/css/
This title block is built into my theme and is available based on the design for the page I select.
But I was wondering if this block is available separately from Bootstrap, like a Navbar, panel, well, etc. component, that I can just include some HTML/CSS code and have it appear in the body of a page, for example.
No it's not in bootstrap but it's pretty easy to grab the style and use it anywhere:
.bs-docs-header {
font-size: 24px;
padding-bottom: 60px;
padding-top: 60px;
text-align: left;
}
.bs-docs-masthead, .bs-docs-header {
background-color: #6F5499;
background-image: linear-gradient(to bottom, #563D7C 0px, #6F5499 100%);
background-repeat: repeat-x;
color: #CDBFE3;
padding: 30px 15px;
position: relative;
text-align: center;
text-shadow: 0 1px 0 rgba(0, 0, 0, 0.1);
}

If you look at their source, they are using a stylesheet called docs.min.css, they have defined the background in here. Other then that it is just a simple <div class="container"><!--title and subtitle here-->. So the answer is a yes and a no. You can, of course, use containers seperately from your CMS when using bootstrap, but the background will not be available unless you strip it from the getbootstrap.com source.
Edit
If you see their styles, they are using this code in their docs.min.css:
#media (min-width: 768px)
.bs-docs-header h1 {
font-size: 60px;
line-height: 1;
}
}
This means, when the width of your window is above 768 pixels, it gives the h1 a font-size of 60px. When you fall under it, this code is ignored and the default bootstrap font-size is being applied.
Edit 2
To get a background-color behind it, don't apply the background color to the .container. wrap a div around it without a width value. The container width is not full width, so if you apply a background to it, its only behind the container that is centered.
Edit 3
A simple HTML structure would be something like this (you still have to include all bootstrap styles and default html tags etc.
<html>
<body>
<div id="bgColorDiv">
<div class="container">
<h1>My title</h1>
<p>Paragraph below the title</p>
</div>
</div>
</body>
</html>
I'm updating an older html page with CSS, which I've just started getting into. The new version looks good, but there are huge empty spaces now at the bottom and right of the page when the user scrolls.
The nature of the page is several different content boxes, all of which have graphical backgrounds.
The old method I was using was to use a large table to organize the layout and give the table one large, solid background image. A colleague pointed out this was too old-school and suggested I try learning divs and css.
The newer version I produced broke each box up into separate divs and images and positioned them absolutely, but there was no way to keep the content centered if the browser window was resized.
I redid the whole page again, this time using relative positioning and one main container div that I could center. Everything looks good and stays centered, but now I'm getting big blank spaces on the bottom and right sides because of the positioning.
I've seen some people say they've fixed this by using a negative margin, but it doesn't seem to be having any effect on my page (unless I'm putting it in the wrong spot).
I need to know if there's a specific way to fix this that I don't know about or if I'm just going about the whole page completely the wrong way. How can I get my elements lined up correctly, centered, and with no extra scroll space? Should I just go back to using a table?
Here's a simplified version of the page with the content taken out (just the layout):
<!DOCTYPE html>
<html>
<meta charset="utf-8">
<style type="text/css">
body
{
background-color: black;
margin-bottom: -2000px;
}
div.main
{
width: 1100px;
margin-left: auto;
margin-right: auto;
margin-bottom: -2000px;
}
div.logo
{
position: relative;
left: 40px;
top: 60px;
z-index: 1;
}
div.window1
{
position: relative;
left: 320px;
top: -555px;
z-index: 1;
}
div.window2
{
position: relative;
left: 320px;
top: -580px;
z-index: 1;
}
div.window3
{
position: relative;
left: 680px;
top: -1250px;
z-index: 2;
}
div.window4
{
position: relative;
left: 25px;
top: -1570px;
z-index: 1;
}
</style>
<div class="main">
<div class="logo">
<img src="images/logo8.png">
</div>
<div class="window1">
<img src="images/window1_fullsize.png">
</div>
<div class="window2">
<img src="images/window2_fullsize.png">
</div>
<div class="window3">
<img src="images/window3_fullsize.png">
</div>
<div class="window4">
<img src="images/window4_fullsize.png">
</div>
</div>
</html>
You could use "em" or "%" values for top and left.
But the best be to handle this using JS.
Hope this helps.
I fixed this some time ago. I eventually did go back to using a table for the layout (which I understand is frowned upon) combined with a little bit of relative positioning, but I made sure everything was done with css and was w3 compliant:

The inherent problem, I think, is the way I designed my older pages, visually. They were highly graphical and usually made up of one contiguous background image, with a lot of art making up the section borders, etc. The general layouts tended to be unusual shapes, and I would then over-lay text and content on top on that. Unfortunately, it's very difficult to get looking right if the sections are separated.
I've since designed newer pages using only divs and css and it seems to work well, although it's a bit trickier to get working. The key, I think, is to come up with a look and style that I know is going to work using that technique from the start.
