Differences Between em and px
Em is a relative unit that scales according to the font size of the element it is used on. Pixels (px) are an absolute unit, with one pixel being a single dot on a screen. Em units are useful for scalable and responsive design, while pixels provide precision.
Advantages of Using em
Using em units allows for better scalability and flexibility in web design. Since em is relative to the font size of the parent element, it enables elements to scale proportionally. This is useful for responsive design and for respecting user preferences for font size.
How to Convert em to px
To convert em to pixels, you need to know the font size of the element. By default, most browsers set the font size to 16px. The formula for conversion is:
px = em * font size
For example, to convert 2em to pixels, assuming the font size is 16px:
2em * 16px = 32px
