Differences Between em and vmax
Em is a relative unit that scales according to the font size of the element it is used on. Viewport Maximum (vmax) is a relative unit that scales according to 1% of the larger dimension of the viewport (either height or width). Em units are useful for scalable and responsive design, while vmax units provide a way to size elements relative to the larger 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 vmax
To convert em to viewport maximum, you need to know the font size of the element and the larger dimension of the viewport. The formula for conversion is:
vmax = em * (font size * 100 / larger viewport dimension)
For example, to convert 2em to viewport maximum, assuming the font size is 16px and the larger viewport dimension is 1920px:
2em * (16px * 100 / 1920px) = 1.6667vmax
Frequently Asked Questions
Why should I use em instead of vmax?
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.
