Nested flex containers with overflow and ellipsis not working - html

Question

I have trouble getting text-overflow: ellipsis and overflow: hidden working the way I need it.
Basically, I need to get the left div with class item1 and text "Please truncate me" to shrink as the width of the container decreases so that both item1 and item2 are on the same row.
No matter what I try I end up with the row overflowing and it never shrinks.
Tried various solutions from here but didn't manage to get any working the way I need.
.mainwrapper {
display: flex;
justify-content: center;
width: 100%;
max-width: 100%;
height: 100%;
max-height: 100%;

display: flex;
align-items: center;
justify-content: center;
margin-top: 20px;
margin-bottom: 20px;
max-width: 800px;
width: 100%;
height: 400px;
background-color: red;
}
.top-container {
display: flex;
flex-wrap: wrap;

}
.skills-container {

Answer 1

An initial setting on flex items is min-width: auto. This means that, by default, an item cannot shrink below the size of its content. This prevents the ellipsis from rendering since the item simply expands to accommodate all content.
Most of your flex items have the necessary min-width: 0 override applied. But not all of them.
Also, flex and table properties don't play well together. Mixing them can break a flex layout, which appears to be happening in your case.
With the following adjustments, your layout seems to work.
.table-container {
/* display: table; */
min-width: 0; /* NEW */
}
.item-content {
display: flex;
min-width: 0; /* NEW */
}

Why doesn't flex item shrink past content size?
