Align button at the bottom of div using CSS

Question

I want to align my button at the bottom right corner of my div. How can I do that?

Current css of div:

    float: right;
    width: 83%;
    margin-right: 0px;
    font-family: Arial, Helvetica, sans-serif;
    font-size: 12px;
    height:625px;
    overflow:auto;

Answer 1

Parent container has to have this:

position: relative;

Button itself has to have this:

position: relative;
bottom: 20px;
right: 20px;

or whatever you like

Answer 2

CSS3 flexbox can also be used to align button at the bottom of parent element.

Required HTML:

<div class="container">
  <div class="btn-holder">
    <button type="button">Click</button>
  </div>
</div>

Necessary CSS:

.container {
  justify-content: space-between;
  flex-direction: column;
  height: 100vh;
  display: flex;
}
.container .btn-holder {
  justify-content: flex-end;
  display: flex;
}

Answer 3

You can use position:absolute; to absolutely position an element within a parent div. When using position:absolute; the element will be positioned absolutely from the first positioned parent div, if it can't find one it will position absolutely from the window so you will need to make sure the content div is positioned.

To make the content div positioned, all position values that aren't static will work, but relative is the easiest since it doesn't change the divs positioning by itself.

So add position:relative; to the content div, remove the float from the button and add the following css to the button:

position: absolute;
right:    0;
bottom:   0;

Answer 4

Goes to the right and can be used the same way for the left

.yourComponent
{
   float: right;
   bottom: 0;
}
