Given some text that occupies about 10 rows, how can I resize its container to only show the first 3 rows and hide the others? Apparently this works, but I think it is not relia
you can set the line height of a text and with it knows the exact height of each row and set desired height of your container, simply doing this:
.container {
line-height:25px;
height:75px;
overflow:hidden;
}
Now everything works rightly :)
The ex unit is the font x-height (height of its x character). I would not use this here. You should use the em unit. This is the actual font-height. The font-height is defined by setting the line-height property. So:
.container {
height: 3em; /* 1em for each visible line */
overflow: hidden;
}
Here is some more info on CSS length units: http://www.w3.org/TR/CSS21/syndata.html#length-units
You can use the webkit property line-clamp
.container {
overflow: hidden;
display: -webkit-box;
-webkit-line-clamp: 3;
-webkit-box-orient: vertical;
}
It doesn't work on all browsers, but hopefully it will one day.
Use rem
:
.container {
height: 3rem; /* 1rem for each visible line */
overflow: hidden;
}
If you are going to use this you should ensure the line-height
is always 2.5ex
.container {
line-height: 2.5ex;
height: 7.5ex; /* 2.5ex for each visible line */
overflow: hidden;
}
