Align an element to bottom with flexbox

Question

I have a div with some children:

<div class="content">
  <h1>heading 1</h1>
  <h2>heading 2</h2>
  <p>Some more or less text</p>
  <a href="/" class="button">Click me</a>
</div>

and I want the following layout:

 -------------------
|heading 1          |
|heading 2          | 
|paragraph text     |
|can have many      |
|rows               |
|                   |
|                   |
|                   | 
|link-button        |
 -------------------

Regardless how much text is in the p I want to stick the .button always at the bottom without taking it out of the flow. I've heard this can be achievable with Flexbox but I can't get it to work.

Answer 1

Try

content{
  display:flex; 
  flex-direction:column; 
  justify-items:space-between; 
  heigh:100vh
}

Answer 2

<section>
  <div class="top">
    <div class="search-box">
         ... bla-bla-bla 
    </div>
    <div class="processing">
      Do something...
    </div>
  </div>

  <button class="select-lesson">
    Select Lesson
  </button>
</section>

CSS:

section {
display:flex;
flex-direction: column;
}

section {
  box-sizing: border-box;
  width: 100%;
  height: 400px;
  background: yellow;
  color: blue;
  padding: 1.8em;
  border-radius: 1.4em;
  font-family: 'Roboto', sans-serif;
  display: flex;
  margin: 25px 0;

 /* This line does the trick */ 
 justify-content: space-between;
}

.top {
  width: 100%;
}

button.select-lesson, .search-box {
  border-radius: 0.6em;
}

.search-box {
  padding: 1.6em 1.7em;
  background: #232323;
}

.search-box svg {
  display: block;
}

.processing {
  text-align: center;
  padding: 4.5em 0;
  font-size: 1.5em;
}

button.select-lesson {
  border: 0;
  width: 100%;
  background: #14274B;
  color: #9FB8EA;
  text-align: center;
  font-weight: bold;
  font-size: 1.5em;
  padding: 1.7rem;
}

Answer 3

If it's fine to modify your HTML, you can wrap all your top elements in a separate div and then use justify-content: space-between.

Something like this:

<div class="content">
  <div>
    <h1>heading 1</h1>
    <h2>heading 2</h2>
    <p>Some more or less text</p>
  </div>
  <a href="/" class="button">Click me</a>
</div>

.content {
  display: flex;
  flex-direction: column;
  justify-content: space-between;
}

Answer 4

1. Style parent element: style="display:flex; flex-direction:column; flex:1;"

2. Style the element you want to stay at bottom: style="margin-top: auto;"

3. Done! Wow. That was easy.

Example:

section {
  /* ONLY FOR DEMO, NOT NECESSARY */
  display: flex;
  flex-wrap: wrap;
}

div {
  /* PARENT ELEMENT */
  display: flex;
  flex-direction: column;
  flex: 1;
}

button {
  /* TARGET ELEMENT */
  margin-top: auto;
}

/* DECORATIVE STYLES FOR DEMO */

button {
  font-size: 20px;
  background-color: crimson;
  color: white;
  border-style: none;
  border-radius: 3px;
}

section {
  margin: 0;
  padding: 0;
  border: 1px solid black;
  background-color: crimson;
}

div {
  font-size: 20px;
  background-color: khaki;
  border: 2px dashed black;
  margin: 10px;
  padding: 10px;
  min-width: 400px;
  min-height: 300px;
}

<section>

    <span>Lorem ipsum dolor s at mi imperdiet fringilla vitae id lorem. Donec ut semper sapien, et ullamcorper metu</span>

Answer 5

<div class="content">
    <h1>heading 1</h1>
    <h2>heading 2</h2>
    <p>Some more or less text</p>
    <a href="/" class="button">Click me</a>
</div>

Notes for CSS:

1. Change the height of .content as you need
2. Button will take the whole empty area at the bottom because of the flex:1 property, making the whole area clickable. I will advise wrapping the button in a div or span

CSS

.content {
    display: flex;
    flex-direction: column;
    height: 100vh;
}

.button {
    display: flex;
    flex: 1;
    align-items: flex-end;
}

Answer 6

When setting your display to flex, you could simply use the flex property to mark which content can grow and which content cannot.

Flex property

div.content {
 height: 300px;
 display: flex;
 flex-direction: column;
}

div.up {
  flex: 1;
}

div.down {
  flex: none;
}

<div class="content">
  <div class="up">
    <h1>heading 1</h1>
    <h2>heading 2</h2>
    <p>Some more or less text</p>
  </div>

  <div class="down">
    <a href="/" class="button">Click me</a>
  </div>
</div>

Answer 7

I just found a solution for this.

for those who are not satisfied with the given answers can try this approach with flexbox

CSS

    .myFlexContainer {
        display: flex;
        width: 100%;
    }

    .myFlexChild {
        width: 100%;
        display: flex;

        /* 
         * set this property if this is set to column by other css class 
         *  that is used by your target element 
         */
        flex-direction: row;

        /* 
         * necessary for our goal 
         */
        flex-wrap: wrap;
        height: 500px;
    }

    /* the element you want to put at the bottom */
    .myTargetElement {
        /*
         * will not work unless flex-wrap is set to wrap and 
         * flex-direction is set to row
         */
        align-self: flex-end;
    }

HTML

    <div class="myFlexContainer">
        <div class="myFlexChild">
            <p>this is just sample</p>
            <a class="myTargetElement" href="#">set this to bottom</a>
        </div>
    </div>

Answer 8

The solution with align-self: flex-end; didn't work for me but this one did in case you want to use flex:

Result

 -------------------
|heading 1          |
|heading 2          | 
|paragraph text     |
|                   |
|                   |
|                   | 
|link button        |
 -------------------

Code

Note: When "running the code snippet" you have to scroll down to see the link at the bottom.

.content {
  display: flex;
  justify-content: space-between;
  flex-direction: column;
  height: 300px;
}

.content .upper {
  justify-content: normal;
}

/* Just to show container boundaries */
.content .upper, .content .bottom, .content .upper > * {
  border: 1px solid #ccc;
}

<div class="content">
  <div class="upper">
	  <h1>heading 1</h1>
	  <h2>heading 2</h2>
	  <p>paragraph text</p>
  </div>

  <div class="bottom">
	  <a href="/" class="button">link button</a>
  </div>
</div>

Answer 9

Not sure about flexbox but you can do using the position property.

set parent div position: relative and child element which might be an <p> or <h1> etc.. set position: absolute and bottom: 0.

Example:

index.html

<div class="parent">
  <p>Child</p>
</div>

style.css

.parent {
  background: gray;
  width: 10%;
  height: 100px;    
  position: relative;
}
p {
  position: absolute;
  bottom: 0;
}

Code pen here.

Answer 10

You can use display: flex to position an element to the bottom, but I do not think you want to use flex in this case, as it will affect all of your elements.

To position an element to the bottom using flex try this:

.container {
  display: flex;
}

.button {
  align-self: flex-end;
}

Your best bet is to set position: absolute to the button and set it to bottom: 0, or you can place the button outside the container and use negative transform: translateY(-100%) to bring it in the container like this:

.content {
    height: 400px;
    background: #000;
    color: #fff;
}
.button {
    transform: translateY(-100%);
    display: inline-block;
}

Answer 11

Try This

.content {
      display: flex;
      flex-direction: column;
      height: 250px;
      width: 200px;
      border: solid;
      word-wrap: break-word;
    }

   .content h1 , .content h2 {
     margin-bottom: 0px;
    }

   .content p {
     flex: 1;
    }

   <div class="content">
  <h1>heading 1</h1>
  <h2>heading 2</h2>
  <p>Some more or less text</p>
  <a href="/" class="button">Click me</a>
</div>

Answer 12

You can use auto margins

Prior to alignment via justify-content and align-self, any positive free space is distributed to auto margins in that dimension.

So you can use one of these (or both):

p { margin-bottom: auto; } /* Push following elements to the bottom */
a { margin-top: auto; } /* Push it and following elements to the bottom */

.content {
  height: 200px;
  border: 1px solid;
  display: flex;
  flex-direction: column;
}
h1, h2 {
  margin: 0;
}
a {
  margin-top: auto;
}

<div class="content">
  <h1>heading 1</h1>
  <h2>heading 2</h2>
  <p>Some text more or less</p>
  <a href="/" class="button">Click me</a>
</div>

Alternatively, you can make the element before the a grow to fill the available space:

p { flex-grow: 1; } /* Grow to fill available space */

.content {
  height: 200px;
  border: 1px solid;
  display: flex;
  flex-direction: column;
}
h1, h2 {
  margin: 0;
}
p {
  flex-grow: 1;
}

<div class="content">
  <h1>heading 1</h1>
  <h2>heading 2</h2>
  <p>Some text more or less</p>
  <a href="/" class="button">Click me</a>
</div>
