I need to fix a button at the bottom of an ionic 3 project page.
The actual scss script works but the button is not totally fixed to the bottom, and it moves while scrolling.
Here is the sass script:
.fixedBtn{
width: 100%;
position: fixed;
left: 0;
bottom: 10px;
right: 0;
}
I tried to use flex:
div{
display: flex;
flex-direction: column;
}
But the result was as shown in this stackblitz, not the right behavior.
put this :
<button ion-button primary class="fixedBtn">a</button>
out side of ion-content
should be like
<ion-content>
/** your content */
</ion-content>
<button ion-button primary class="fixedBtn">a</button>
and in your sass file :
.fixedBtn{
width: 100%;
position: fixed !important;
left: 0;
bottom: 50px;
right: 0;
}

I've created a navbar element in react that sits behind whichever page component is being rendered at the time. I've done this so that when the nav menu button is clicked the users current page is scaled down and moved partially off screen, revealing the nav menu and displaying a miniature version of the page off to the side. The problem is that if the user has scrolled down the page then as soon as the transition happens the scroll position is reset to the top. Is there anyway to maintain the scroll position?
Here is my html:
Home Page
<div id="home" className={`${props.homeState === true ? "" : "collapsed"}`}>
<div style={{height: "1000px"}}>
<Header toggleExpansion={props.toggleExpansion} />
<h1 style={{margin: "0"}}>Test nav when there is scrollable content</h1>
</div>
</div>
Navbar
<div className="navbar-background">
<div className={`navbar ${props.navState === false ? "hidden" : ""}`}>
... content ...
</div>
</div>
and css:
Home page
#home {
background-image: url("../../images/tall-tall-wall.png");
background-attachment: scroll;
background-position: 80% 20%;
background-repeat: no-repeat;
background-size: 120%;
width: 100%;
height: 100vh;
position: absolute;
transition: box-shadow .6s, border-radius, transform 0.3s ease-in-out;
z-index: 1;
}
.collapsed {
border-radius: 10px;
box-shadow: 0 0 2rem 1rem rgb(15, 15, 15), inset 0 0 8rem;
transform: translateX(40%) scale(50%);
}
Navbar
.navbar {
display: flex;
flex-direction: column;
height: 100vh;
justify-content: space-between;
position: fixed;
top: 0;
transition: transform 0.4s ease-in-out;
width: 100%;
}
.navbar-background {
background-image: radial-gradient(at 90%, rgb(15, 15, 15), rgb(45, 45, 45));
height: 100vh;
position: fixed;
width: 100%;
z-index: -1;
}
.hidden {
transform: translateX(-85%);
}
I've tried changing the navbar position to fixed so that it scrolls along with the home page (as well as the navbar background) but that hasnt seemed to work. Messed around with positioning and overflow, but to no avail
Hopefully that's clear, I've been teaching myself over the past few months so point out any glaring mistakes in my code structuring or method.

I am working on a simple app in Ionic.
I have a problem that the keyboard pushes my input field up and over another div while there is enough space for they keyboard. How do I fix this? I already looked around on the internet but wasn't able to find any solution to my problem.
This is what happens:
As you can see, the text is in the image and there is no reason for it being so high. There is more then enough space below it.
This is my code:
HTML:
<ion-header>
<ion-navbar>
<ion-title>Login</ion-title>
</ion-navbar>
</ion-header>
<ion-content padding class="login content">
<div class="logo-container">
<img src="assets/imgs/Mikos_logo.jpeg" class="logo-img">
</div>
<div class="center">
<p>Vul hier je naam in:</p>
<ion-item class="code-field">
<ion-input placeholder="naam" type="text" (keyup)="nameInput()" [(ngModel)]="name"></ion-input>
</ion-item>
</div>
</ion-content>
CSS:
page-login {
.login {
background-color: #EEEEEE;
}
.logo-container{
position: absolute;
width: 400px;
left: calc(50% - 400px / 2);
}
.logo-img{
display: block;
width: 100%;
height: auto;
}
.center{
position: absolute;
top: 40%;
width: 300px;
left: calc(50% - 300px / 2);
}
#media only screen and (max-width: 600px) {
/* For mobile phones: */
.logo-container{
position: absolute;
width: 300px;
left: calc(50% - 300px / 2);
}
}
}
What I have tried:
I have added the Ionic native keyboard and added this in my app module:
IonicModule.forRoot(MyApp, { scrollAssist: false, autoFocusAssist: false } ),
This unfortunately did not work.
Update:
Adding
.scroll-content {
padding-bottom: 0 !important;
}
is also not working.
This is a known bug of Ionic 3 and can be fixed by adding the following CSS style:
.scroll-content {
padding-bottom: 0 !important;
}
I have had similar issues and this piece of CSS fixed it.
When an input is focused, Ionic adds some padding to the bottom of the scroll-content class, to create room for the keyboard.
Update
Relative top positioning may cause the issue (as well).

Basically just go to your AndroidManifest.xml file,
search for:
android:windowSoftInputMode=ABC
Replace "ABC" with adjustPan
Just add this to your config.xml and make sure you have your keyboard plugin installed.
<preference name="KeyboardResizeMode" value="ionic" />
I have a page in my ionic application that on button click opens a Modal Page. Currently, I have override the variable.scss to the code below to make the model cover the 100% of the page.
//for Modals
$modal-inset-height-large: 100%;
$modal-inset-height-small: $modal-inset-height-large;
$modal-inset-width: 100%;
However, this applies for all my models in my application. I want to use some models in other pages that use the 50% of the width and around 80% of the height. How can I customize my controls?
You can not change a particular modal height or width.
Now, I will describe an solution which I use to resize my modal.
Ensured that all modal height and width should be 100%. As ionic
resize modal for large screen devices. That's why I added below code
in app.scss.
modal-wrapper {
position: absolute;
width: 100%;
height: 100%;
}
#media not all and (min-height: 600px) and (min-width: 768px) {
ion-modal ion-backdrop {
visibility: hidden;
}
}
#media only screen and (min-height: 0px) and (min-width: 0px) {
.modal-wrapper {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
}
}
Now In ion-content we make two div and the background of ion-content should be transparent (see main-view css class). Now, One div is used for background of the modal, this will use as backdrop (see overlay css class). Another div should be used for the content, we will resize this div (see modal-content css class).In example I resize the height to 50%. Sample html ans css code is given below,
page-about {
.main-view{
background: transparent;
}
.overlay {
position: fixed;
top: 0;
width: 100%;
height: 100%;
z-index: 1;
opacity: .5;
background-color: #333;
}
.modal_content {
position: absolute;
top: calc(50% - (50%/2));
left: 0;
right: 0;
width: 100%;
height: 50%;
padding: 10px;
z-index: 100;
margin: 0 auto;
padding: 10px;
color: #333;
background: #e8e8e8;
background: -moz-linear-gradient(top, #fff 0%, #e8e8e8 100%);
background: -webkit-linear-gradient(top, #fff 0%, #e8e8e8 100%);
background: linear-gradient(to bottom, #fff 0%, #e8e8e8 100%);
border-radius: 5px;
box-shadow: 0 2px 3px rgba(51, 51, 51, .35);
box-sizing: border-box;
-moz-box-sizing: border-box;
-webkit-box-sizing: border-box;
overflow: hidden;
}
}
<ion-content class="main-view">
<div class="overlay" (click)="dismiss()"></div>
<div class="modal_content">
<h2>Welcome to Ionic!</h2>
<p>
This starter project comes with simple tabs-based layout for apps that are going to primarily use a Tabbed UI.
</p>
<p>
Take a look at the <code>src/pages/</code> directory to add or change tabs, update any existing page or create new
pages.
</p>
</div>
</ion-content>
Here is a screen shot of the modal,
If you want modal content should scroll then replace <div class="modal_content"> with <ion-scroll class="modal_content" scrollY="true"> as told by Missak Boyajian in comment
For Ionic3 you need to this comment from Alston Sahyun Kim.
this is an excellent answer, just one thing from ionic3, .main-view{ background: transparent; } should be .content{ background: transparent; }
All the code is taken from here. I think this project repo will help you.
I tried before but had not found a generic way to make modals behave the way as I desired.
So I strugled a bit and achieved responsive modals and other kinds of modals with the following global scss:
ion-modal {
&.my-modal-inner {
display: flex;
align-items: center;
justify-content: center;
ion-backdrop {
visibility: visible;
}
.modal-wrapper {
display: flex;
align-items: flex-start;
justify-content: center;
overflow: auto;
width: auto;
height: auto;
left: auto;
top: auto;
contain: content;
max-width: 70%;
max-height: 70%;
border-radius: 2px;
box-shadow: 0 28px 48px rgba(0, 0, 0, 0.4);
> .ion-page {
position: relative;
display: block;
width: auto;
height: auto;
contain: content;
box-shadow: 0 28px 48px rgba(0, 0, 0, 0.4);
}
}
&.my-stretch {
.modal-wrapper {
overflow: hidden;
width: 100%;
height: 100%;
> .ion-page {
width: 100%;
height: 100%;
}
}
}
}
&.my-fullscreen {
.modal-wrapper {
position: absolute;
display: block;
top: 0;
left: 0;
width: 100%;
height: 100%;
}
}
}
You can have responsive modals that will have the size of the inner content using cssClass: 'my-modal-inner':
The modal will occupy at maximum 70% of the width and height (like defined in the above css) when the content surpasses the limit:
If the content of the modal is supposed to occupy all the container element (like a page or a component with ion-content), it will not work well with the above case because the modal supposes that the container should have the size of its children, causing a possibly undesired behaviour (the modal will be very small, more than it should):
Instead, you can define the modal to occupy its maximum size with cssClass: 'my-modal-inner my-stretch':
If you want the modal to be full screen, even in a large desktop browser, you can use cssClass: 'my-fullscreen':
Notes:
You can change the prefix my- with any other prefix of your choice (or no prefix).
You can change the maximum width and height of the modal in the above css, as you seem fit (I defined both as 70%, in your case it would be 50% and 80% for the width and height, respectively).
The above screenshots were taken in a desktop browser, but the modal changes also work in a mobile/native app with Ionic (I tested in Android, and it should work in iOS too).
Update (2018-07-30)
About the HTML codes for the modal:
1) Responsive modal that will be as large or as small as the inner content (a single div or a hierarchy of divs, spans and other block and inline elements should do):
<div class="main">
<div class="img-container">
<img src="assets/img/main/icon.png" [alt]="APP_NAME">
</div>
<div class="info-container">
<div class="app-name">{{ APP_NAME }}</div>
<div class="app-version">Version {{ APP_VERSION }}</div>
<div class="app-year">#{{ INITIAL_YEAR }}-{{ CURRENT_YEAR }} {{ APP_NAME }}</div>
<div class="app-rights">All rights reserved</div>
</div>
</div>
2) Modal will occupies its maximum size (use class my-stretch). In this case, any ionic page will do:
<ion-header>
<ion-navbar>
<ion-title>My Title</ion-title>
</ion-navbar>
</ion-header>
<ion-content>
<p> My content </p>
</ion-content>
I'm using Element.scrollIntoView(). The scrolling is working, but it breaks the layout of my whole page at the same time. Following is the demo:
* {
margin: 0;
padding: 0;
}
html, body {
width: 100%;
height: 100%;
}
.content {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
overflow: hidden;
background-color: lightgray;
}
ul {
position: absolute;
width: 100%;
height: 300px;
left: 0;
bottom: 0;
background-color: gray;
overflow-y: scroll;
}
li {
list-style: none;
}
#div {
position: absolute;
width: 100%;
height: 300px;
left: 0;
bottom: -300px;
background-color: darkgray;
}
button {
position: absolute;
right: 0;
bottom: 0;
}
<div class=content>
<!-- it's the ul to scroll, staying at the bottom of the page -->
<ul>
<li id=li>abc</li>
<li>def</li>
</ul>
<!-- it's the div hidden under the bottom edge of the page -->
<div id=div>i should stay hidden.</div>
<button onclick=li.scrollIntoView();>scrollIntoView</button>
</div>
I hide a <div> under the bottom edge of the page. When I scrollIntoView the 1st <li> in <ul>, the hidden <div> is pulled out. Not only the <div>, the whole content of the page is pulled up for 300px.
I expect it to simply scroll the <li> into view of <ul>. Why is it affecting the layout of the whole page?
I think I find the answer myself. See this answer. It's about anchors, but scrollIntoView share the same mechanism internally I think.
The browser will try best to ensure the element is visible. When it's in a container, it will first scroll the container to a position with best visibility, so the contents are pulled up.
First of all I have to say:
what a phantastic piece of software!
Well designed, implemented and documented, and many, many cool features.
Tanks a lot for giving that away as Open Source!
Now I have made a slider implementation for the "Gambio GX"-shopsystem (a very advanced osCommerce fork.)
You can see it here in action: http://marmorkamin-shop.de/Test/
I have used all image transformations (377) and caption animations (438) available, both are randomly selected for each slide...
(Resulting in 163,618(!) different ways to change slides....)
The slider is dynamically generated with PHP, based on slide-information in the shops database....
As inline-styles are very inflexible in such an environment, I have moved the styling to a stylesheet.
It already works like a charm, almost....
Two problems I am encountering:
The caption area is sometimes clipped
(see 1st caption in this picture: screenshot)
Only bullets 1, 2 and 3 in the bullet navigator are active, the others do not respond.
Any idea what could be the reason for this??
Thx again for this great software!
Edit:
The caption area is sometimes clipped (see 1st caption in this
picture: screenshot)
Found a quick and dirty solution for this meanwhile:
Assign a clip: auto !important; CSS direktice for the caption elements...
But I am sure there must be a better solution :-)
Re: caption clipped
Please always specify width and height for caption.
You can specify width and height in css file,
.slide_caption_1 {
left: 100px; top: 200px; width: 110px; height: 29px;
}
.slide_caption_2 {
left: 150px; top: 250px; width: 110px; height: 29px;
}
.slide_caption_3 {
left: 200px; top: 300px; width: 110px; height: 29px;
}
And you can specify inline style as well,
<div class="jssor_slide_caption slide_caption_1" data-u="caption" t="*" style="width: 110px; height: 30px;"></div>
Re: bullet problem
Style for 'mousedown' of bullet navigator not specified.
Given class of navigator item prototype is 'jssor_navigator_entry', the class name for 'active' state is 'jssor_navigator_entryav', the class name for 'mousedown' state is 'jssor_navigator_entrydn'
So, please add following css code in slideshow.css file.
.jssor_navigator_entrydn {
padding: 5px 0px 0px; border: currentColor; border-image: none; width: 27px; height: 24px; text-align: center; color: white !important; font-weight: bold !important; text-decoration: none; margin-right: 0px; float: left; display: block; position: relative !important; z-index: 9; cursor: pointer; background-color: rgb(50, 22, 1);
}
Here is an example to define bullet navigator in a simple way,
<script>
var jssor_options={
...
$BulletNavigatorOptions: { //[Optional] Options to specify and enable navigator or not
...
$SpacingX: 5, //[Optional] Horizontal space between each item in pixel, default value is 0
...
}
...
};
<script>
<!-- Bullet Navigator Begin -->
<style>
.the_navigator{
position: absolute;
bottom: 0px;
}
.the_navigator_item, .the_navigator_itemdn, .the_navigator_itemav {
position: absolute;
width: 27px;
height: 24px;
line-height: 24px;
color: #fff;
font-weight: bold;
background-color: #321601;
text-align: center;
cursor: pointer;
}
.the_navigator_item:hover, .the_navigator_itemav {
background-color: #d1013f;
}
</style>
<!-- bullet navigator container -->
<div class="the_navigator" data-u="navigator">
<!-- bullet navigator item prototype -->
<div class="the_navigator_item" data-u="prototype"><numbertemplate></numbertemplate></div>
</div>
<!-- Bullet Navigator End -->
