Differences Between em and vmin
Em is a relative unit that scales according to the font size of the element it is used on. Viewport Minimum (vmin) is a relative unit that scales according to 1% of the smaller dimension of the viewport (either height or width). Em units are useful for scalable and responsive design, while vmin units provide a way to size elements relative to the smaller viewport dimension.
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 vmin
To convert em to viewport minimum, you need to know the font size of the element and the smaller dimension of the viewport. The formula for conversion is:
vmin = em * (font size * 100 / smaller viewport dimension)
For example, to convert 2em to viewport minimum, assuming the font size is 16px and the smaller viewport dimension is 1080px:
2em * (16px * 100 / 1080px) = 2.963vmin
Frequently Asked Questions
Why should I use em instead of vmin?
Using em allows for more scalable and flexible layouts within the context of the current element's font size, improving the responsiveness and accessibility of your design.
How do I set the font size?
You can set the font size using CSS on the parent element. For example:
parent-element {
font-size: 16px;
}
Can I use em for all elements?
Yes, you can use em for most elements to ensure consistency and scalability within the context of the current element's font size.
