How to make divs wrap *only* at their max-width, and not because its parent container is being overflown?

Question

I have a parent container with a fixed size, and absolutely positioned child divs inside it. The position of the child divs have dynamic text content a

Don't use left to position the element but consider translate instead. The left property will restrict the width of your element.

/* Relevant parent and child styles */

.parent {
  position: relative;
  width: 500px;
  height: 400px;
}

.child {
  position: absolute;
  max-width: 250px;
}


/* Individual positioning of child elements */

#fine {
  top: 30px;
  transform: translateX(100px);
}

#wrapped {
  top: 90px;
  transform: translateX(400px);
}

#unwrapped {
  top: 200px;
  left: 170px;
}
#extra {
  top: 300px;
  left: 170px;
}



/* The rest is only styles to make the example easier on the eye */

body {
  background-color: hsl(0, 0%, 90%);
  margin: 0;
  padding: 24px;
}

.parent {
  background-color: white;
  border: 2px solid grey;
}

.child {
  padding: 12px;
  background: yellowgreen;
}

  

    Text should be wrapped normally with the max-width of the child, like this
  
  

    This text will be wrapped much earlier though because it is running out of the parent container
  
  

    "white-space: nowrap" only prevents *all* wrapping
  
  
   

    short text
  

Or consider a big negative margin (at least equal to max-width) to negate the use of left:

/* Relevant parent and child styles */

.parent {
  position: relative;
  width: 500px;
  height: 400px;
}

.child {
  position: absolute;
  max-width: 250px;
  margin-right:-250px;
}


/* Individual positioning of child elements */

#fine {
  top: 30px;
  left:100px;
}

#wrapped {
  top: 90px;
  left: 400px;
}

#unwrapped {
  top: 200px;
  left: 170px;
}
#extra {
  top: 300px;
  left: 170px;
}


/* The rest is only styles to make the example easier on the eye */

body {
  background-color: hsl(0, 0%, 90%);
  margin: 0;
  padding: 24px;
}

.parent {
  background-color: white;
  border: 2px solid grey;
}

.child {
  padding: 12px;
  background: yellowgreen;
}

To understand how both tricks work you need to refer to the specification where you can find the formula to calculate the width of your element:

The constraint that determines the used values for these elements is:

'left' + 'margin-left' + 'border-left-width' + 'padding-left' + 'width' + 'padding-right' + 'border-right-width' + 'margin-right' + 'right' = width of containing block

You can then read the different case where some values are specified and other auto
