Outer DIV not shrink-wrapping - html

Question

I have display inline-block etc. but the htmlDiv div in this mark-up does not behave as I expected. It behaves as if the inner divs are beside each other even when they are not. How to fix this?
Please run the animated snippet if it's not clear...
var demoContainer = d3.select('#demoContainer').style('width', '100px')
function tick() {
demoContainer.transition().duration(4000).style('width', '400px')
.transition().duration(4000).style('width', '600px')
.transition().duration(3000).style('width', '400px')
.transition().duration(3000).style('width', '100px')
.each('end', tick);
};
tick();
#htmlDiv {
font-family: 'Helvetica Neue', Helvetica, 'Segoe UI', Arial, freesans, sans-serif;
font-size: 12px;
outline: solid 1px black;
background-color: rgba(0, 0, 0, 0.25);
display: inline-block;
position: relative;
}
.container {
height: auto;
width: 100%;
display: inline-block;
position: relative;
}
.bubbles,
.subBubbles,
.span {
color: #ccc;
}
.select-bubbles,
.bubbles {
padding: 5px;
margin: 3px;
outline: solid 1px white;
background-color: rgb(114, 114, 114);
width: 150px;
display: inline-block;
}

Answer 1

The Problem with your were you were setting width for 250px in the below code
.select-bubbles, .bubbles {
padding: 5px;
margin: 3px;
outline: solid 1px white;
background-color: rgb(114, 114, 114);
/* width: 250px; */
/* display: inline-block; */
}
Remove the inline-block and setting your width to 250px which causes your box not to shrink less than 250px.
We are removing the inline-block for the time being if u want u can add it with some more properties to make it look good.

Answer 2

Your question is unclear but I think you want to do the following:
.container,
.select-bubbles,
.bubbles {
display: block;
}
Instead of inline-block.
