CSS Overflow Property Utilization

Summary

When utilizing the CSS overflow: hidden property, developers often encounter issues, particularly with table cells. While generally effective for containing overflowing content, applying overflow: hidden directly to a td element will fail, causing the cell's height to expand rather than hiding the text. The key to successful implementation is ensuring the container element has a defined height to prevent default text wrapping. For td cells, the recommended approach is to embed a div element within the td and apply both the height and overflow: hidden properties to this inner div to achieve the desired text truncation.

Sometimes when we do CSS on HTML elements. We may want to hide some text when the text in a specified box overflows. Usually, we can use a CSS property overflow:hidden to hide the text so that the format of the whole element will not be affected. But will it always work?

I believe some of us may encounter problems when we want to hide some text in a table td cell with specified width. If we use td { overflow:hidden;}, it is supposed to hide the text if the text in a td cell overflows. But the fact is that it will fail to work.The outcome will be the height of the td cell will increase so that the text can be contained in the td cell and visible. Then what should we do to hide text in a td cell? Following some tips : 
 
1. When we use overflow property, we must set the height property of the container box to make sure the text will not wrap up in the container box. By default, the text will wrap up when the text length is larger than the container box width, so the height of the container box will automatically increase. So a height property must be set when use overflow property.
 
2, a td cell can not be used to hide text, it will always increase the height of td cell when the text overflows even if you set the overflow:hidden property on td cell. So to make the text hide in a td cell, we suggest that users use a div container in a td cell, then use the overflow property on the div container. This will help you hide the text when it overflows.
 
One example
 
//CSS Code
td div{
height:20px;
overflow:hidden;
}

//Html code
<table>
<tr><td><div> Some text here</div></td></tr>
</table>
Some text here
 
Hope this can help to solve your problem when you encounter problems to use overflow:hidden in td cells.
