Difference Between a View'S Padding and Margin

Difference between a View's Padding and Margin

To help me remember the meaning of padding, I think of a big coat with lots of thick cotton padding. I'm inside my coat, but me and my padded coat are together. We're a unit.

But to remember margin, I think of, "Hey, give me some margin!" It's the empty space between me and you. Don't come inside my comfort zone -- my margin.

To make it more clear, here is a picture of padding and margin in a TextView:

xml layout for the image above

Android beginner difference between padding and margin

Padding is for inside/within components. Eg. TextView , Button, EditText etc.

Eg. space between the Text and Border

Margin is to be applied for the on-outside of the components.

Eg. space between left edge of the screen and border of your component

Visual representation is great in : Difference between a View's Padding and Margin

With Padding, i have seen a difference in 2.2, 2.3 and say 4.3, 4.4

in such cases:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:text="ASDFGHJKL" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:paddingLeft="15dp"
        android:text="@string/hello_world" />

</RelativeLayout>

what's the difference between padding and margin?

Padding is the space INSIDE an element (inside the border of the element).

Margin is the space OUTSIDE(Around) an element.

When to use margin vs padding in CSS

TL;DR: By default I use margin everywhere, except when I have a border or background and want to increase the space inside that visible box.

To me, the biggest difference between padding and margin is that vertical margins auto-collapse, and padding doesn't.

Consider two elements one above the other each with padding of 1em. This padding is considered to be part of the element and is always preserved.

So you will end up with the content of the first element, followed by the padding of the first element, followed by the padding of the second, followed by the content of the second element.

Thus the content of the two elements will end up being 2em apart.

Now replace that padding with 1em margin. Margins are considered to be outside of the element, and margins of adjacent items will overlap.

So in this example, you will end up with the content of the first element followed by 1em of combined margin followed by the content of the second element. So the content of the two elements is only 1em apart.

This can be really useful when you know that you want to say 1em of spacing around an element, regardless of what element it is next to.

The other two big differences are that padding is included in the click region and background color/image, but not the margin.

div.box > div { height: 50px; width: 50px; border: 1px solid black; text-align: center; }div.padding > div { padding-top: 20px; }div.margin > div { margin-top: 20px; }

<h3>Default</h3><div class="box">  <div>A</div>  <div>B</div>  <div>C</div></div>
<h3>padding-top: 20px</h3><div class="box padding">  <div>A</div>  <div>B</div>  <div>C</div></div>
<h3>margin-top: 20px; </h3><div class="box margin">  <div>A</div>  <div>B</div>  <div>C</div></div>

body {
  box-sizing: border-box,
  margin: 1px,
  padding: 0
}
