The default template/project that is used for a MVC 4/5 web application re-sizes according to your screen size. If you are on a tablet or phone it will re-size the text/layout when you manually re-size the screen. Is there any easy way to just turn this off or do I have to create a new project with my own css? I would like the template to stay at a fixed width.
Mvc5 templates used bootstrap.
From bootstrap page: How to disable page responsiveness
Omit the viewport mentioned in the CSS docs. In your razor layout remove:
"<meta name="viewport" content="width=device-width, initial-scale=1.0">"
Override the width on the .container for each grid tier with a single width, for example width: 970px !important; Be sure that this comes after the default Bootstrap CSS. You can optionally avoid the !important with media queries or some selector-fu.
If using navbars, remove all navbar collapsing and expanding behavior.
For grid layouts, use .col-xs-* classes in addition to, or in place of, the medium/large ones. Don't worry, the extra-small device grid scales to all resolutions.

I'm working on a responsive email template for my employer. For the desktop size, I was able to leave the default font size at 16px and just use rem to adjust sizes as necessary. It looks fine on the desktop, in Gmail, and is fully responsive. However, when viewed in Mail on iPhone, the font is SO SMALL. I had to add a media query that increases the base font size to 26px to get reasonable font sizes in the email. I've tried doing some research, but it doesn't seem as if other people have had to do the same. There is very little CSS in the code, but here is what I have:
body, table, td, a, p, span {-webkit-text-size-adjust: 100%; -ms-text-size-adjust: 100%;}
#media screen and (max-width: 600px) {
html, td {
font-size: 26px !important;
line-height: 1.3;
}
}
I also have
<meta name="viewport" content="width=device-width, initial-scale=1">
There is some other CSS having to do with resizing images, with margins, etc. but that is the only CSS dealing with font-sizes (all the rem info is inline so it isn't stripped out by Bronto/Gmail). If I resize it in the browser to a mobile size, the text looks massive, but when viewed on my iPhone, it looks great. I'm concerned that this may be an iPhone quirk though and that it will look massive on other types of devices. Does anyone have any insight?
Here is some code from the templates I use (where I don't see this issue):
Try making your <meta> tags look more like this:
<meta name="x-apple-disable-message-reformatting">
<meta name="viewport" content="width=device-width">
The first tag disables auto-scale in iOS 10 Mail, which could be affecting your text size. The second tag sets the viewport; forcing initial-scale shouldn't be necessary and could be throwing off your design.
Also try moving the inline body styles from the <body> tag to inside a universal selector in <style>, like so:
<style>
/* What it does: Stops email clients resizing small text. */
* {
-ms-text-size-adjust: 100%;
-webkit-text-size-adjust: 100%;
}
</style>
<body width="100%" bgcolor="#ffffff" style="margin: 0; mso-line-height-rule: exactly;">
Have you heard of the viewport meta tag? You should consider adding this tag to the meta on your site. Just be cautious though as it could manipulate other HTML elements you have already configured.
<meta name="viewport" content="width=device-width, initial-scale=1">
Here is a link to a page explaining what it does in further detail.
https://developer.mozilla.org/en/docs/Mozilla/Mobile/Viewport_meta_tag
Okay, finally figured it out. Luckily I had been going through and making all our email templates responsive, and one of them didn't have a hero image. Guess what? The font size looked massive on mobile for the imageless-template! So after some experimentation, I found that
img {
width: 100% !important;
}
completely resolved the issue, so that now the actual font-size matches what is set in the CSS. Despite all the width:100% styles set on the image itself and on its parent containers, somehow the image must have been too large and triggered a resize of all content, I guess? If anyone has an explanation I'd love to hear it.
FWIW, I think you are complicating your life trying to use the text-size-adjust property.
According to the browser compatibility chart on this MDN document, there is poor browser support and it's buggy.
Secondly, the way I read this W3C doc I don't think you are using it for its intended purpose. W3C states that:
This module contains features of CSS relating to one possible
mechanism for adapting pages designed for desktop computer displays
for display on smaller screens such as those of mobile phones...
Its purpose is to provide a solution for pages which were designed for desktop display only.
As you know, older web pages which don't use the viewport meta tag will be scaled down to fit the viewport of a mobile device. The problem with this is that text often becomes too small to read and this text-size-adjust property proposes to remedy this by enlarging text on mobile devices.
I think if you continue to use the viewport meta tag, make your template responsive, and size elements so that they display well in all devices you would get good results if you don't use text-size-adjust, i.e. some like the following:
body, table, td, a, p, span {font-size:16px;}
Good sources of info about text-size-adjust:
https://developer.mozilla.org/en-US/docs/Web/CSS/text-size-adjust?v=control

I am developing a Cordova application which previously used the JQuery mobile 1.4.5 script. A previous problem on Android, where transitioning from a page to another caused unnecessary flickering left me no choice but to remove the call to the JQuery mobile script.
<script src="js/jquery.mobile-1.4.5.js"></script>
Instead I simply left the CSS
<link href="js/jquery.mobile-1.4.5.css" rel="stylesheet" />
and used the JQuery mobile classes to change the styles of inputs, buttons, etc, retaining the previous app style (this was highly important especially considering that the app is almost finished and the design in which jquery mobile was heavily used needed to be retained).
When I did this I found out that on iOS the scrolling was no longer fast and smooth as it was before. I tried to revert to the old method, i.e. having the j-query mobile script and the iOS smooth works normally. This proves that J-Query mobile had some specific script that 'fixes' the iOS scroll. I would like to use just this script to fix the scrolling problems. Apart from this problem, the app works and looks just fine.
Below is the 'template' html of every page. As you can see the jquery-mobile classes that are normally automatically wrapped around the components of the app after the page loads are manually assigned to the specific components.
<html class="ui-mobile js csstransitions">
<head>
</head>
<body class="ui-mobile-viewport ui-overlay-a sidy--panels-closed">
<div class="sidy ui-page ui-page-theme-a ui-page-active">
<nav>Menu</nav>
<nav>Search</nav>
<div class="sidy__content">
<div id="wrapper" class="wrapper">
<div>Fixed header</div>
<div>Container</div>
<div>Fixed Footer</div>
</div>
</div>
</div>
<script></script>
</body>
<html>
I tried to search intensively on stackoverflow and other sources. For e.g. this fix did not work when tried on the tag; as the fixed header and footer move with the scrolling and only restore to their original position when the scrolling operation is finished. When trying to assign the class on the container (where the actual scrolling needs to happen); nothing happens.
cssClass{
overflow-y: scroll;
-webkit-overflow-scrolling: touch;
}
What would be most useful to me is to know which part of the Jquery mobile script makes the iOS scrolling look smooth and native and act very fast!
Thank you for your help!
Your css'ed div needs for IOS (Safari) to have a non-dynamic size in the scroll direction, i.e. the height in your example.
Add a height element:
cssClass{
overflow-y: scroll;
-webkit-overflow-scrolling: touch;
height: ...px;
}
and it should work.
I had the same problem, and was able to solve it with this added property. I use React.JS so, I could easily get computed the height so that it was correct for different devices, adjusted for headers and footers etc. With Javascript you can do compute it with the variable window.innerHeight (at least for Cordova, I don't know if this is a standard browser variable).
I have an existing Ruby on Rails 4 application and I have set up bootstrap within. The buttons, forms and other small things I've utilised have been great!
Now I am absolutely perplexed when it comes to bootstrap and responsive design. From what I've read, embedding bootstrap into your app should be responsive out of the box, but this doesn't seem to be the case (or maybe I'm doing it wrong).
In my application.html.erb head tag I have:
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1">
I've looked at this section on the bootstrap site, but I don't see how adding hidden/visible classes is going to help my case, especially when header/footer widths need to change when the browser gets smaller.
I've been doing stuff like this so far:
#media only screen and (min-width : 175px) and (max-width : 400px) {
/* styles here for 175px to 400px */
}
So what I've been doing is setting up my own media queries. Now my question is: IS setting up media queries necessary when using the bootstrap framework? I've had some OK success so far using my own queries, but it's very, very tedious: everything on my site looks pretty good when the browser is large, but when it gets small, everything goes to shit.
If anyone could offer some insight on this, it would be much appreciated. I feel like I'm making responsive design much harder than it ought to be.
Integrate bootstrap into your app does not mean your website become responsive. It depends on the elements and classes that you are using on your site. If you have lots of custom CSS classes then you will need to define your own #media query.
In this case, I think you should take a deeper look into your app to see if you are really using Bootstrap classes in all places. If you see strange behaviors on mobile devices, then it should be because of your custom CSS classes
If you look into bootstraps documentation, bootstrap 3 has a lot of css features which will help you to make your app responsive.
Grid System:
Bootstrap 3 provides you grid classes according to your device like: col-md-1(for medium size desktop), col-sm-1(for your tablet) ,col-xs-1(for your mobile) so if you want to resize a particular element according to your device you can give that element classes like:
<div class="col-md-8 col-sm-4 col-xs-2"></div>
Now this div will have different width depending on the device width.
Media Queries:
Bootstrap 3 use the following media queries in our Less files to create the key breakpoints in grid system.
/* Extra small devices (phones, less than 768px) */
/* No media query since this is the default in Bootstrap */
/* Small devices (tablets, 768px and up) */
#media (min-width: #screen-sm-min) { ... }
/* Medium devices (desktops, 992px and up) */
#media (min-width: #screen-md-min) { ... }
/* Large devices (large desktops, 1200px and up) */
#media (min-width: #screen-lg-min) { ... }
Media queries will be helpful if you want to change typography or want to override any style according to device
Images:
Images in Bootstrap 3 can be made responsive-friendly via the addition of the .img-responsive class. This applies max-width: 100%; and height: auto; to the image so that it scales nicely to the parent element.
Responsive Utilities
For faster mobile-friendly development, use these utility classes like .visible-xs, .visible-sm etc for showing and hiding content by device. You can simply apply these classes to any element and they will be visible or hidden according to your device
I have a simple page with
<meta name="viewport" id="extViewportMeta" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0, user-scalable=no">
on it, with everything sized nicely to display on an iPhone.
But when I put an iframe on that page, everything inside the iFrame is not zoomable, and scales to the size of the parent page.
How can I allow zooming within the iframe only, without messing with the rest of my page?
What you are requesting is unfortunately not possible.
First off, in you 'viewport' meta tag, your "content" attribute is specifying that the user of your website CAN NOT zoom at all. That is what the 'user-scalable=no' dictates.
Also, your maximum-scale and minimum-scale is set to 1, so even if you remove the 'user-scalable=no', the zooming would disabled by the fact that you there is no scaling range for the user to zoom within.
So to enable zooming for the user you will have to remove the user-scalable=no and set different min and max scale values.
See this link to better understand the settings for the 'viewport' meta tag:
https://developer.apple.com/library/safari/documentation/AppleApplications/Reference/SafariHTMLRef/Articles/MetaTags.html
Secondly, since your 'viewport' meta tag is set on your 'parent' page, these settings apply to anything within that page, i.e the iframe too. Whether the iframe has a different meta 'viewport' tag specifying different settings does not matter since it lives within and abides by the settings of its parent.
This is possible via jQuery. Bind the zooming and panning events to not do anything when zooming and panning outside the divs that you allow zooming and panning. Then for the divs you want to allow zooming and panning, you can use plugins like Panzoom that use "CSS3 transforms and matrix functions" to allow for zooming and panning.
This is not possible as iOS does not allow zooming - you just can scroll through your iFrame.
Is this an external site, that you own? If so, change the CSS code and add it the to viewport like in your question on the top.
Alternatively, you can load the data with PHP. You will surely find a solution for your problem - if not, feel free to ask follow-up questions.
I love the way jquery mobile renders a form, is it possible to embedded a jquery-mobile-form in a table, div or any container in my webpage?, to be clear: I have a html5 webpage anf the layout is done by divs and css, is it possible to include a jquery-mobile-form in one of the divs.
I have been tried to do that but jquery-mobile-form always takes the 100% of the page, I want to use the form in an specific high/with div container, is that possible?
Thanks!
Yes, you can adjust the size of this forms like any other div elements.
Just wrap the form in a block element and apply the css "width"-attribute on it.
I created a Fiddle for that:
