Differences Between vw and rem
Viewport Width (vw) is a relative unit that scales according to 1% of the width of the viewport. Root Em (rem) is also a relative unit, but it scales according to the root element's font size, typically the HTML element. vw units are useful for scalable and responsive design, while rem units provide consistency across different elements.
Advantages of Using vw
Using vw units allows for better scalability and flexibility in web design. Since vw is relative to the width of the viewport, it enables elements to scale proportionally to the viewport size. This is useful for responsive design and for creating layouts that adapt to different screen sizes.
How to Convert vw to rem
To convert vw to rem, you need to know the width of the viewport and the root font-size. The formula for conversion is:
rem = vw * (viewport width / 100 / root font-size)
For example, to convert 2vw to rem, assuming the viewport width is 1920px and the root font-size is 16px:
2vw * (1920px / 100 / 16px) = 2.4rem
Frequently Asked Questions
Why should I use vw instead of rem?
Using vw allows for more scalable and flexible layouts, improving the responsiveness and adaptability of your design across different screen sizes.
How do I set the viewport width?
The viewport width is determined by the user's device and browser window size. You can use CSS media queries to adjust your layout based on different viewport widths.
Can I use vw for all elements?
Yes, you can use vw for most elements to ensure consistency and scalability across different screen sizes.
