I'm working on a web site that needs a fairly complex print layout. Within one of the printable areas is a Google map - iframe version.
But I can't get the map to print.
I've created a test HTML page containing minimal HTML/CSS/JS to demonstrate the problem.
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="idHead">
<title>iFrame inside .visible-print</title>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" type="text/css" />
<style media="print">
.visible-print-block {
border: 10px solid red !important;
width: 620px !important;
height: 470px !important;
display: block !important;
}
.visible-print iframe {
border: 10px solid blue !important;
}
</style>
</head>
<body>
<div class="visible-print visible-print-block">
<iframe src="https://www.google.com/maps/embed?pb=!1m18!1m12!1m3!1d2418.4013212105515!2d-1.656887048290665!3d52.68884797974762!2m3!1f0!2f0!3f0!3m2!1i1024!2i768!4f13.1!3m3!1m2!1s0x0%3A0x0!2zNTLCsDQxJzE5LjkiTiAxwrAzOScxNi45Ilc!5e0!3m2!1sen!2suk!4v1567617099057!5m2!1sen!2suk" width="600" height="450" frameborder="0" style="border:0;" allowfullscreen=""></iframe>
</div>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
</body>
</html>
Expected results is a blank web page when you view it in the browser, but the print preview (and the print) would show a red bordered area containing the map.
What I get is an empty red bordered area.
I added the blue border to the iframe to show where the iframe should be and to check the iframe is showing.
I've looked through the Bootstrap CSS and can't see how the 'visible-print' 'visible-print-block' could affect the iframe or the Google map.
If I take the iframe out of the container div it appears and prints correctly.
Google maps cannot render on a hidden div. If you need to print this, i suggest you to create another page just to print.

Padding property started behave strange (in browser) after i had tried to create one-page scrollable website. Basically initially I had my index.html file linked to the styles.css file. I wanted to create one-page site so I googled it and found this site:
https://www.turnwall.com/articles/adding-single-page-scrolling-navigation-to-your-site/
I followed the instructions: created side-bar and some sections to test it, but without using js script. It all worked perfectly except 1 thing: titles in side bar werent highlithing when scrolling, so I tried to implement the script (I created new file and paste the code from tutorial) and this is the part when it started to behave strangly: basically my title which was located also in side bar got much larger and padding around all page elements appeared. BUT THATS NOT ALL: that padding is still there (even after I deleted all elements and created everything from scratch), which I suppose shoudnt be there.
I want to get rid of it. Here is screenshot from my browser:
here
On the screenshot you can see 1 elemeent with some text. The thing is that I suppose that this text should be in the very top left corner but it is not.
Here are my index.html and styles.css files:
HTML:
<!doctype html>
<html>
<head>
<title>RA TOOLKIT</title>
<meta name="description" content="Our first page">
<meta name="keywords" content="html tutorial template">
<link rel="stylesheet" href="styles.css">
</head>
<body>
<div class="nav-menu">eha</div>
</body>
</html>
CSS:
body{
background-color: red;
display: flex;
flex-direction: row;
padding-top: 0px;}
.nav-menu{
background-color: white;
transition: all .2s;
width: 25vw;
min-height: 100%;
box-sizing: border-box;}
.nav-menu:hover{
background-color: greenyellow;}
Thanks in advance!
(sorry for my english : D )
When I tried to inspect element the page, i found that your html body has an 8px margin that you thought was the padding. I don't really know what caused this, but you can just overwrite the styling by giving a
body {
margin: 0px
}
to your html body. You can always use inspect element to figure out your final style render of your page
Here's the extremely simple HTML page
<body style="overflow-y: hidden">
...
</body>
The expected behavior of this page is: scrolling of a document is prevented because of overflow-y: hidden.
It works as expected (scrolling is prevented) everywhere except Safari.
Live demo: https://spotted-chime.glitch.me/
The question is: how to make Safari behave the same way as other browsers?
Just use overflow: hidden and it will work.
Alternatively, you can try using position: fixed on the <body> tag as well.
(NOTE: Using this approach, the body will scroll to the top as by default the top: 0.)
EDIT: For safari mobile devices, you need to use Javascript events. Explained in this answer.
https://stackoverflow.com/a/4770179/2860486
Position fixed is meant to create a div that stays in the same position on the screen while the content behind it is scrolled down.
fixed
The element is removed from the normal document flow, and no
space is created for the element in the page layout. It is positioned
relative to the initial containing block established by the viewport,
except when one of its ancestors has a transform, perspective, or
filter property set to something other than none (see the CSS
Transforms Spec), in which case that ancestor behaves as the
containing block. (Note that there are browser inconsistencies with
perspective and filter contributing to containing block formation.)
Its final position is determined by the values of top, right, bottom,
and left.
This value always creates a new stacking context. In printed
documents, the element is placed in the same position on every page.
Have you tried changing it to absolute?
body {
overflow-y: hidden;
}
#backdrop {
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
background: rgba(0, 0, 0, .2);
border: 5px dashed black;
}

Try this:
<head>
<style>
.forSafari::-webkit-scrollbar { width: 0 !important }
</style>
</head>
<body style="overflow-y: hidden" class="forSafari">

</body>
just use "position: relative" or fixed it will resolve the problem
I need the background image to stay centered because I am going to display charts in fixed positions and want the van (in the image) always to be visible. It's working fine in Chrome etc but nothing appearing in IE8.

My guess would be that while your div is 100% height, that's 100% of zero. Try stretching both the body and html elements to 100%, too, and see if that does the trick.
body, html {
height: 100%;
}
Also, as Adrift mentions, you'll be a lot better off adding an appropriate DOCTYPE to your HTML, otherwise Internet Explorer will probably run in "quirks mode" and really confuse you.
When I shrink the browser width I expect the header div to shrink along with the browser and take up the entire width of the page. Instead the div stops at the browser width and then there is blank space to the right and a horizontal scroll bar. This seems to be a problem with the way I'm using bootstrap but I can't figure it out. Any help appreciated
I'm using the latest minified bootstrap css in my project and have completely simplified my layout below.
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<link rel="stylesheet" type="text/css" href="style.css" />
<link rel="stylesheet" type="text/css" href="bootstrap.min.css" />
</head>
<body>
<div class="row">
<div class="header">
<div class="container">
<p>Lorem ipsum dolor sit amet</p>
</div>
</div>
</div>
</body>
</html>
css:
body {
background-color: #CDE0E4;
width: 100%;
}
.header {
position: relative;
height:120px;
background-color:#CDE0E4;
box-shadow: 0 0px 15px #272727;
}
Thanks
What you need is fluid layout (see the docs). This term means that your content takes most available width and is resized when browser window is resized. In this case you should use .container-fluid and .row-fluid instead of their unsuffixed versions.
But you are misusing some of Bootstrap's classes.
.row
Is used when you want to create a multi-column layout. For this you have .span* classes to use inside it (see the docs for examples).
.container
Is used when you want your content to have a white space on the sides (it will be 20px for .container-fluid and maximum available for .container).
.header
If you are using HTML5 (which you do by declaring <!doctype html>), why not to use <header> instead of <div class="header">?
<div class="container">
should come at the top. Row is nested inside container and finally the column is nested inside row. You have reversed the order. That is one problem with your code.
I am new to the world of coding as well as XHTML. I am in the process of putting a sample page together however having read a number of conflicting articles, it has been suggested that the navigation div block appear above the content div block or vice versa or does it not matter at all? Below is my base code as an example.

I think you need to elaborate your question. I am unable to figure it out that whether you are concern with SEO or HTML code. Declaring dive any where is not an SEO issue. But for better readability it would be better to make your web page in order.
Like Header at the top. Content in center and footer at the bottom. Left or right navigation menus can be mention before or after content but i suggest that first you should make left nav, then content and then right....
Ideally from an SEO perspective you would want the most important code to appear highest in the HTML source. This is one of the many factors that potentially contribute to how important certain content within a page is perceived to be to search engines.
If it were me I would make the following adjustments to the base template provided
Move the content div above the navigational elements within the source code.
Move the inline CSS code to an external CSS file to help reduce page load times and allow the most important content to move even higher in the source code.
The advice to put the navigation block before the content block is not SEO related, but usability related, in particular for those with screen readers.
The idea is to put a first (invisible to graphical browsers) link to the content of the page so navigation can be bypassed.
Your code is wrong, but here's how you can fix it:
You are using XHTML so you must include XML language information, also you should just include your general language info in your HTML declaration like this:
Microsft's Bing would flag this as an error and inform you to change it appropriately.
Don't use margins, or floats! This is like saying, ok, please move this element a little towards the left and kind of towards the right. Makes no sense! Use absolute positioning and percentages to place elements in your webpages CSS. There are too many different size screens and too many resolutions today. Float and margin are 1995, and I have no idea why people are still using these methods. We also have a society that is now driven by mobile. Keep in mind, one pixel on device will be larger or smaller than one pixel on another device. You can have 5 laptops that are all 17 inches and all have completely different resolutions! Its ok to specify a fixed pixel width and height for images and elements, but you must use percentages when placing those elements otherwise they won't appear in the right position on alternate devices and LCD screens.
If you position an element using absolute positioning with a percentage value such as:
"position: absolute; left: 30%; top: 5%;", then that particular element will be displayed on the screen at 30% from the left, and 5% from the top of the screen regardless of the device rendering it! However, if you position an element with a fixed pixel value say:
"position: absolute; left: 160px; top: 45px;" this will not render correctly on any screen other than the one you are viewing it on. Don't do this! Think about it? You have 2 separate resolutions, one is 1024x768, and the other is, 1366x768, obviously using fixed values will cause serious problems. A percentage is a percentage of the screens or browsers resolution, while a pixel value is a fixed value that hardly changes.
As for your question, you can include your navigation or any other content any way you wish, just be sure to use CSS ID's and corresponding DIV tags that map back to them. Doesn't matter where or when you specify them in your CSS at all. Its entirely up to you. Just stay away from all that "padding" and "margin" stuff, its pointless. With absolute positioning you don't have to float anything, cause everything goes exactly where you want it too from either the top-left, or bottom-right of the screen.
