How to lock ionic 3 website screen orientation in Portrait mode while opening in mobile browser?
Can anyone please provide any suggestion on this?
It is not possible using any plugin. But can be achieved using mediaqueries. Try adding below CSS code in your .css file:
#media screen and (min-width: 320px) and (max-width: 767px) and (orientation:
landscape) {
html {
transform: rotate(-90deg);
transform-origin: left top;
width: 100vh;
height: 100vw;
overflow-x: hidden;
position: absolute;
top: 100%;
left: 0;
}
}
referring to the documentation, try to use this in your app.ts:
import { ScreenOrientation } from '#ionic-native/screen-orientation';
constructor(private screenOrientation: ScreenOrientation) {
this.screenOrientation.lock(this.screenOrientation.ORIENTATIONS.PORTRAIT_PRIMARY);
}

I've been making the website responsive and even tools like protoFluid to view it as if it was on an iPhone. However, I used my iPhone and there are numerous problems. The buttons does not seem to want to change their widths even though they are based on percentages. They are overflowing to the right and leaving a black space to the right.
.container .name .social div{
width: 80px;
display: inline-block;
}
.container .name .social img{
width: 100px;
}
.social {
position: absolute;
display: inline;
width: 425px;
left: 0;
margin-left: 10px;
}
#media only screen and (max-width: 600px) {
.social {
padding: 0;
width: 424px;
position: relative;
display: block;
margin: 0 auto
}
.name .social div {
width: 16.6666667%;
}
.social img {
width: 125%;
/*width: 100px*/
}
}
#media only screen and (max-width: 450px) {
.container .name .social div {
width: 13.6667%;
}
.container .name .social img {
width: 125%;
}
}
there are many ways to solve it, include using bootstrap framework... I always use a "resize window" chrome plugin(found in appstore here) , and the error is showed. And you can work it in your dev enviroment.
The buttons stay the same because the percentage width is decided on the size of parent controller. On line 271 of stylesheet.css .social class has width 425px (the same width it has on each screen size) so the buttons stay the same. Try changing width of .social class or simply use pixels for button dimensions for that media-query - #media only screen and (max-width: 600px)
What I want to do is make the div of the opt-in box at the top on the posts and pages stretch across. I wanted to do it using the width:100% attribute in CSS, but it was only stretching across partway.
So I manually set the width to the # of pixels that would make it 100%. But the problem with that is that it is causing display issues on iPhone/iPad.
Is there a way to have the width of a div change on iPhone/iPad to fit to scale? How could I do this?
Thank you!

Check out the section regarding viewport:

You can make use of "device-width".
try
#youroptinid { max-width: 1600px; width: 100%; clear: both; }
if that doesn't work please post your html and css code so we can help you. Without code we can only speculate.
I'd appreciate a bit of advice from someone skilled with CSS. For a reason I can't pinpoint, only the right side of my website shows up in iPhone / iPad browser, and the left 1/3rd of it can't even be seen.
If someone could explain what causes the issue and how it can be fixed, I'd be grateful.
Here's the part of css that sets the layout:
body {
position:absolute;
width: 960px;
top: 0px;
left: 50%;
margin-left: -480px;
}
First: Try to remove this (position: absolute; width: 960px; top: 0px; left: 50%; margin-left: -480px;) from your body.
Second: here's how to center a page width: 960px; margin: auto, put that on #page
So with the some css on body removed and the css below on #page it may work better
#page {
width: 960px;
margin: auto;
overflow: hidden; /* to compensate for some element overflowing and messing up your layout */
}
you need to modify the width of your body on every device.
You can use #media query to do it by css
/* Ipad Landscape */
#media screen and (max-width: 1100px) {
body {
width: 80%;
left: 0%;
margin-left: 10%;
}
}
/* iphone 5 landscape ipad portrait */
#media screen and (max-width: 800px)
{
}
/* iphone 4 lanscape */
#media screen and (max-width: 500px)
{
}
/* iphone 4- 5 portrait */
#media screen and (max-width: 400px)
{
}
I would like to have my website look perfect using mobile safari on both the ipad and iphone. Currently everything looks great in landscape on some pages, but if you change the device to portrait, the whole site gets zoomed in. I am using mobile specific styles, but how can I fix this problem?
Page that doesn't work: www.zedsaid.com/apps
Page that DOES work: www.zedsaid.com/blog
CSS:
/* iPhone */
#media only screen and (max-device-width: 481px) {
#header {
width:860px!important;
}
}
/* iPad */
#media only screen and (max-device-width: 768px) {
#header {
width:860px!important;
}
}
I am just not sure why some of my pages scale correctly (blog) but other pages (apps, contact) do not!
Try this:
body * {
-webkit-text-size-adjust: none !important;
}
or:
/* iPhone */
#media only screen and (max-device-width: 481px) {
#header {
width: 860px;
-webkit-text-size-adjust: none;
}
}
/* iPad */
#media only screen and (max-device-width: 768px) {
#header {
width: 860px;
-webkit-text-size-adjust: none;
}
}
I have a mobile website, which currently displays a timetable. The non-mobile site however also has a iFrame with google maps inside it, to display multiple vehicles being tracked.
For the mobile site, I want only the timetable to display in portrait and only the iframe to display in landscape.
I've seen this Can I trigger a CSS event in mobile safari upon iphone orientation change? , but I struggle to see how I can apply this to my query.
This is the CSS for the iFrame:
.map {
-moz-border-radius: 5px;
-webkit-border-radius: 5px;
background-color: #fff;
color: #000;
width: 600px;
height: 500px;
margin-left: 20px;
margin-right: auto;
overflow: hidden;
-moz-box-shadow: inset 0 0 5px #888;
-webkit-box-shadow: inset 0 0 5px #888;
box-shadow: inner 0 0 5px #888;
float: left;
}
use #media
#media all and (orientation:portrait) { … }
#media all and (orientation:landscape) { … }
Don't abuse javascript when CSS can do it.
orientation
First you will need to assign ID to your timetable container and iFrame. Then, use the javascript below to hide or display it. I will assume that your iFrame id is 'map' and your timetable container is 'timetable'
<script type="text/javascript">
var timetable = document.getElementById('timetable');
var map = document.getElementById('map').
window.onorientationchange = function() {
switch(window.orientation) {
case 0: // Portrait
case 180: // Upside-down Portrait
// Javascript to setup Portrait view
timetable.style.display = 'none';
map.style.display = 'block';
break;
case -90: // Landscape: turned 90 degrees counter-clockwise
case 90: // Landscape: turned 90 degrees clockwise
// Javascript to steup Landscape view
timetable.style.display = 'none';
map.style.display = 'block';
break;
}
}
</script>
