padding-top "bigger" than padding-bottom

I don't understand why in this setup the padding-top is various times bigger than the padding-bottom. Tried tweaking stuff around to find the culprit property but so far nothing. I did notice, that I accidentally left a " after the spans, the issue was gone, but not sure how that relates.

https://jsfiddle.net/3n0yuzs3/1/

body
{
  font-family: sans-serif;
}

#window
{
    background-color: black;
    color: white;
    display: flex;
    flex-direction: column;
    opacity: 1;
    left: 50%;
    bottom: 0px;
    position: fixed;
    width: auto;
    height: auto;
    min-width: 600px;
    min-height: auto;
    max-width: 80vw;
    max-height: 80vh;
    transform: translateX(-50%);
    outline: 0px;
    cursor: default;
    z-index: 5000002;
    zoom: 1;  
}

#container
{
    overflow-y: auto;
    overflow-x: hidden;
    border: none;
    outline: 0;
    margin: 0;
    flex-grow: 1;  
}

#content
{
    font-size: 22px;
    text-align: center;
    overflow-wrap: break-word;
    padding-top: 1.6em;
    padding-bottom: 1.6em;
    padding-left: 1.6em;
    padding-right: 1.6em;  
}

.snack_msg
{
    padding-right: 200px;
    float:left;
}

.snack_btn
{
    color:#5fce49;
    text-transform: uppercase;
    letter-spacing:3px;
    cursor:pointer;
    float:right;
}
<div id='window'>
  <div id='container'>
    <div id='content'>
      <span class='snack_msg'>New message arrived</span>
      <span class='snack_btn' onclick='open_snack_message()'>open</span>
    </div>
  </div>
</div>

The issue is with floating elements and not padding. As you can see below, you have equal padding in all the sizes :

enter image description here

And if you check well you will see also that you have a height equal to 0 because you have floating element and since the parent is not floating it will collapse (which means no height). To fix this you need to add oveflow:auto to #content.

body {
  font-family: sans-serif;
}

#window {
  background-color: black;
  color: white;
  display: flex;
  flex-direction: column;
  opacity: 1;
  left: 50%;
  bottom: 0px;
  position: fixed;
  width: auto;
  height: auto;
  min-width: 600px;
  min-height: auto;
  max-width: 80vw;
  max-height: 80vh;
  transform: translateX(-50%);
  outline: 0px;
  cursor: default;
  z-index: 5000002;
  zoom: 1;
}

#container {
  overflow-y: auto;
  overflow-x: hidden;
  border: none;
  outline: 0;
  margin: 0;
  flex-grow: 1;
}

#content {
  font-size: 22px;
  text-align: center;
  overflow-wrap: break-word;
  padding-top: 1.6em;
  padding-bottom: 1.6em;
  padding-left: 1.6em;
  padding-right: 1.6em;
  overflow: auto;
}

.snack_msg {
  padding-right: 200px;
  float: left;
}

.snack_btn {
  color: #5fce49;
  text-transform: uppercase;
  letter-spacing: 3px;
  cursor: pointer;
  float: right;
}
<div id='window'>
  <div id='container'>
    <div id='content'>
      <span class='snack_msg'>New message arrived</span>
      <span class='snack_btn' onclick='open_snack_message()'>open</span>
    </div>
  </div>
</div>

Here is some usefull questions where you can gather more information and more ways to prevent this behavior:

How do you keep parents of floated elements from collapsing?

Why does 'overflow: auto' clear floats? And why are clear floats needed?
