CSS text ellipsis and 100 percent width - html

Question

I have the following container of text:
<div class="cardTitles">
<div class="title">
<div class="titleContent">
<i class="fa fa-star-o"></i>
<b>Some long long long title here</b>
</div>
</div>
... title divs ...
</div>
css:
.cardTitles {
width: 100%;
height: 100%;
}
.title
{
position: relative;
padding-top: 8px;
padding-bottom: 8px;
}
I want to make text full width + text-overflow: ellipsis. So when I resize browser all title divs should be full 100% width of the parent cardTitles with cut text to three dots at the end.
I found that this is possible using flex. Here is the possible answer:
.parent-div {
display: flex;
}
.text-div {
white-space: nowrap;
overflow: hidden;
text-overflow: ellipsis;
min-width: 0;
}
But this doesn't work for me. Parent container stops resizing when it reach the max length of some child title.
You can find an example here: http://88.198.106.150/tips/cpp/
Try to resize browser and look at title with text: What does it mean that a reference must refer to an object, not a dereferenced NULL pointer. I need to make it overflow ellipsis.

Answer 1

Try this out:
.titleContent {
white-space: nowrap;
overflow: hidden;
text-overflow: ellipsis;
}
Here's and updated jsFiddle

Answer 2

No Flex but could work also ... try it.
.element {
display: table;
table-layout: fixed;
width: 100%;
}
.truncate {
display: table-cell;
white-space: nowrap;
text-overflow: ellipsis;
overflow: hidden;
}
text-overflow ellipsis with 100% width

Answer 3

The width needs to be added in pixels, percentage wont work along with other three properties as given below:-
.text-ellipsis{
max-width: 160px;
white-space: nowrap;
overflow: hidden;
text-overflow: ellipsis;
}

Answer 4

#div1 {
white-space: nowrap;
width: 12em;
overflow: hidden;
text-overflow: clip;
border: 1px solid #000000;
}
#div2 {
white-space: nowrap;
width: 12em;
overflow: hidden;
text-overflow: ellipsis;
border: 1px solid #000000;
}
The following two divs contains a long text that will not fit in the box. As you can see, the text is clipped.
This div uses "text-overflow:clip":
This is some long text that will not fit in the box
This div uses "text-overflow:ellipsis":
This is some long text that will not fit in the box
