I tried to override Ionic 2 scss variables to make a smaller with the following code put in my variable.scss:
$chip-button-border-radius: 20%;
$chip-button-size: 20px;
$chip-icon-size: 20px;
The API for chip can be found here
HTML:
<ion-chip color="dark">
<ion-label>Test small chip</ion-label>
</ion-chip>
The chip didn't change.
Am I missing something?

I need your help. I want to make the same header for all my application, so in app.component.html I prescribe ion_toolbar and ion-header before ion-router-outlet. However, I have a problem that this header of mine overlaps the content I have in the ion-router-outlet. I'm trying for the ion-toolbar to give margin-bottom: auto so that there are automatic deviations, but it doesn't react to that. Tell me, what is my mistake, how to make a hat and that it does not overlap the content? Thanks
app.component.html
<ion-app>
<ion-toolbar>
<ion-header>
<div>header</div>
</ion-header>
</ion-toolbar>
<ion-router-outlet></ion-router-outlet>
</ion-app>
app.component.scss
ion-toolbar {
height: 75px;
--margin-bottom: auto;
}
I am developing an application using Ionic 4 and I am using ion-select. I want to customize the select icon, but the style is not applied.
<ion-select interface="popover"
(ionChange)="onSelectionChanged()"
[(ngModel)]="item.Value">
<ion-select-option *ngFor="let option of options" [value]="option.Value">
{{ option.Title }}
</ion-select-option>
</ion-select>
This is the style written in the .scss file, but it is not applied. I've also checked the documentation, but I couldn't find a solution.
.select-icon .select-icon-inner {
margin-top: 0 !important;
border-right: 7px solid transparent !important;
border-left: 7px solid transparent !important;
border-top: 7px solid !important;
}
If you're talking about the little arrow on the right, it seems that it is not possible at least fot the moment, see
issue here
You can use a button and a modal though.
When upgraded to Ionic 5, the padding attribute is not working anymore as in Ionic 4:
<ion-content color="primary" padding></ion-content>
Any fixes?
Story in Ionic v4:
Use of attributes got deprecated in Ionic v4 and if you would have noticed in developers console, Ionic 4 was throwing warnings of using these attributes to style.
Story in Ionic v5:
In Ionic v5, these attributes got removed permanently and got replaced with CSS classes. So even if those attributes there in your code, no effect will be there.
As per the Breaking Changes https://github.com/ionic-team/ionic/blob/v5.0.0/BREAKING.md#css:
We originally added CSS utility attributes for styling components because it was a quick and easy way to wrap text or add padding to an element. Once we added support for multiple frameworks as part of our "Ionic for everyone" approach, we quickly determined there were problems with using CSS attributes with frameworks that use JSX and Typescript. In order to solve this we added CSS classes. Rather than support CSS attributes in certain frameworks and classes in others, we decided to remove the CSS attributes and support what works in all of them, classes, for consistency. In addition to this, changing to classes prefixed with ion avoids conflict with native attributes and user's CSS. In the latest version of Ionic 4, there are deprecation warnings printed in the console to show what the new classes are, and the documentation has been updated since support for classes was added to remove all references to attributes
Solution:
You need to replace all your attributes to CSS classes. For example:
Before
<ion-header text-center></ion-header>
<ion-content padding></ion-content>
After
<ion-header class="ion-text-center"></ion-header>
<ion-content class="ion-padding"></ion-content>
For your case, replace
<ion-content color="primary" padding></ion-content>
to
<ion-content color="primary" class="ion-padding"></ion-content>
Try this,
<ion-content color="primary" class="ion-padding"></ion-content>
According to the official documentation, you can use these CSS custom properties to set padding of ion-content component:
--padding-bottom Bottom padding of the content
--padding-end Right padding if direction is left-to-right, and left padding if direction is right-to-left of the content
--padding-start Left padding if direction is left-to-right, and right padding if direction is right-to-left of the content
--padding-top Top padding of the content
In the SCSS file associated with your component, add:
ion-content {
--padding-bottom: 10px;
--padding-end: 10px;
--padding-start: 20px;
--padding-top: 20px;
}
This should add padding inside the content area.
ion-item {
--padding-start: 10px;
--padding-end: 10px;
--padding-top: 0px;
--padding-bottom: 0px;
--inner-padding-top: 0px;
--inner-padding-bottom: 0px;
--inner-padding-start: 0px;
--inner-padding-end: 0px;
--border-width: 0;
--inner-border-width: 0;
--border-color: transparent;
}
ion-header {
--min-height: auto;
}
In ionic 4 and Ionic 5 the use of padding like this:
<ion-content color="primary" class="ion-padding"></ion-content>
and see https://ionicframework.com/docs/layout/css-utilities
Is there a built-in way to set background color on <ion-content> in Ionic 3?
In Ionic 1, we could set the color scheme for <ion-content> using classes like content-stable. In newer versions of Ionic, you can set the color of certain components with input variables, for example <ion-navbar color="dark"> or <ion-item color="dark">.
I've tried this kind of input on ion-content but without any success. I could set background-color manually, for example style="background-color:#ddd;", but if there is a 'proper' way to do this in Ionic I would rather do that instead. What is the 'official' way to do this?
There is no official way of doing this. Ionic does not provide any attribute or API to change the background color of ion-content directly.
You will have to go through setting up the css yourself.
Just eg:
In your scss file :
.bg-style {
background: red;
}
and apply style to content as in your component Html file :
<ion-content class="bg-style">
In your app.scss add:
.content {
background: #f9f9f9;
}
In .scss file, you can try with:
ion-content { background-color: map-get($colors, dark) !important; }
I'm trying to style a select input on iOS. The first option or initial state should have smaller font-size but not the rest of the options.
I have the following html structure:
<select class="dropdown">
<option selected="" value="Navigation">Navigation</option>
<option value="some-link">Whatever</option>
<option value="some-link">Another option</option>
<option value="some-link">Why</option>
<option value="some-link">What</option>
</select>
My CSS for it looks like this:
select {
-webkit-appearance: none;
font-family: 'Custom-Font', sans-serif;
font-size:.5em
line-height:1.8em; // optical center
background-color: #ccc;
color: #333;
border: none;
padding: 6px 10px 4px 10px;
}
.dropdown {
background-image: url(img/assets.svg);
background-position: right 2px;
background-repeat: no-repeat;
width: 100%;
display:block;
margin-bottom:-1.5em;
option:not(:first-of-type) {
font-size:1.5em;
}
}
The <select> menu looks exactly like I want it to look. It says "Navigation" inside a light-gray box with a rather small font-size.
However when clicking/tapping the select on my iphone the native UI view of iOS shows all options also in a very small font-size.
How can I just make the selected option (or the box itself) use the custom formatting but not the options. I want my options to have a "normal" readable font-size.
Any ideas on that? I tried with option:not(:first-of-type) and increase the font-size but no effect!
Unfortunately, there isn't a way to do it. iOS Safari takes full control of styling select lists' internal contents. Here's a reference for verification: little link.
One way to achieve this this would be to simulate the dropdown/select menu using JavaScript.
It's not very preferable, but if you absolutely require to change the default styling, then I'm afraid it's the only way to go; here's a demo that should give you an idea on how to do the simulation: another little link.
Try this 100% worked for me
select {
-webkit-appearance: none;
-moz-appearance: none;
appearance: none;
}
For what it's worth - I had a transparent <select> dropdown with a border radius when closed. On iOS (I'm not sure about android, I didn't test it) the default grey box for the <select> would appear inside of my custom border which was unappealing and unwanted.
To get rid of the inner grey box I used the following CSS:
-webkit-appearance: none;
