如何去除 ion-item 周围的填充？

Question

I want to remove padding from my ion-item so that it can occupy the full width of the page.

Please look in the dev tools to see the padding around the ion-item.

 <ion-content padding> <ion-list> <ion-item> <ion-thumbnail> <img class="imgmg" src="..."> </ion-thumbnail> <h2>Text</h2> </ion-item> </ion-list> </ion-content>

The ion-item has a padding of 16px, when I inspect the ion-item and also on the class="scroll-content" there I found scss in the inspector with

ion-app.md [padding] .scroll-content {
    padding: 16px;
}

If I remove this padding then ion-item can occupy the whole width by removing this padding, but When I use this in my scss file the padding is not removed.

Answer 1

You can solve ion-item padding different way...

First: Using ion-no-padding class

<ion-item class="ion-no-padding">
  <ion-thumbnail>
    <img class="imgmg" src="...">
  </ion-thumbnail> 
  <h2>Text</h2>
</ion-item>

Second: Using css or inline style

<ion-item style="padding:0px !important;">
  <ion-thumbnail>
    <img class="imgmg" src="...">
  </ion-thumbnail> 
  <h2>Text</h2>
</ion-item>

Edit : As Ionic 5.X we must use CSS utilities by class instead of attributes ( ionic/BREAKING.md ).

Answer 2

For those who are using ionic 4, you should use Ionic CSS Utilties for padding

In short, you have to code this:

<ion-item class="ion-no-padding">
  <ion-thumbnail>
    <img class="imgmg" src="...">
  </ion-thumbnail> 
  <h2>Text</h2>
</ion-item>

If you want to remove inner paddding, use ion-item custom CSS properties :

ion-item {
  --padding-end: 0px;
  --inner-padding-end: 0px;
  // here other custom CSS from documentation
}

Answer 3

I had to use custom CSS properties for ion-item

ion-item {
  --inner-padding-bottom: 0;
  --inner-padding-end: 0;
  --inner-padding-start: 0;
  --inner-padding-top: 0;
}

Answer 4

just give no-padding to ion-item it will remove the padding

<ion-item no-padding>
  <ion-thumbnail>
    <img class="imgmg" src="...">
  </ion-thumbnail> 
  <h2>Text</h2>
</ion-item>

Refer the ionic docs

Answer 5

Also had the same maddening problem. It turns out that ion-item has a few --inner-padding rules that need to be overridden to stop padding appearing on it's children

As well as adding the

class="ion-no-padding"

I also needed to add the following css style rule

--inner-padding-end: 0 !important;

Making the final element

<ion-item *virtualItem="let section" lines="none" class="ion-no-padding" style="--inner-padding-end: 0 !important;">
...

Answer 6

If you prefer not to add no-padding to every ion-item, and remove it for the whole app.

For ionic v4 , you can add this to global.scss:

ion-item {
    --padding-start: 0;
}

Removing padding from the content of the page solves the problem

<ion-content> 
  <ion-list>
    <ion-item>
      <ion-thumbnail>
        <img class="imgmg" src="...">
      </ion-thumbnail> 
      <h2>Text</h2>
    </ion-item>
  </ion-list>
</ion-content>
