ex to pt

Abou · 05-31-2017, 08:06 AM

Hello,

1-Is there a way to change the settings in css from ex to pt?

2-Please note that we also noticed that the conversion formula from ex to pt is wrong. for example:

padding: 0.5ex 5.75pt

while 1 ex should be equal to 4.30554 pt
Corrected padding value: 2.152pt instead of 0.5 ex

thank you

ex is the height of lower case "x" in the current font and so depends on the font selected and the current font size. pt is units of 1/72 inches. There is no fixed conversion ratio between the two units.

You do not want ex or pt. What you want is em.

add the word 'probably' to Jon's answer.

There are a few places where FIXED sizes are needed. They are few. Usually associated with another fixed object, like an image with text overlay.
In general, fixed (absolute) sizes should be avoided. they don't scale

The one thing I tend to do in fixed units are page margins, because I don't want my margins to scale with the text. I use ems for everything else.
