When a table cell does not respect its parent's height, it can cause the entire table to expand unnaturally. This issue is similar to how the table cell does not adhere to the max-height property.
To address this issue, there are two solutions available. One option is to apply position: absolute to the child element.
#main {
width: 100px;
height: 29px;
position: absolute;
top: 20px;
left: 200px;
border: 1px red dashed;
display: table;
table-layout: fixed;
border-spacing: 0;
border-collapse: separate;
}
#child {
position: absolute;
display: table-cell;
}
<div id="main">
<div id="child">Custom Text With Validation:
</div>
</div>
Another approach is to insert an additional element inside the child and set the height on that element.
#main {
width: 100px;
height: 29px;
position: absolute;
top: 20px;
left: 200px;
border: 1px red dashed;
display: table;
table-layout: fixed;
border-spacing: 0;
border-collapse: separate;
}
#child {
display: table-cell;
}
#child div {
height: 29px;
}
<div id="main">
<div id="child">
<div>Custom Text With Validation:</div>
</div>
</div>
Adding overflow: hidden to the table will help contain any excess content more effectively.
