Should I use rem or px CSS
Rem and pixel (px) are two units of measurement frequently used in CSS and HTML to define font size, margin or image size for example. However, the two units have a big difference in terms of web accessibility, because a pixel is not responsive and that's why it'sbetter to use REM.
Is rem better than px
Use px for small, fixed-size elements like borders or shadows. Use em for typography and other scalable elements that need to change size relative to their parent element. Use rem for scalable typography and responsive layouts that need to change size relative to the root element.
Is it good to use px in CSS
The magic unit of CSS, the px , is a often a good unit to use, especially if the style requires alignment of text to images, or simply because anything that is 1px wide or a multiple of 1px is guaranteed to look sharp. But for font sizes it is even better to use em .
What is the difference between px and rem height in CSS
Use em when you specifically want the size of something to depend on the current font size. On the other hand, px or pixel, is an absolute unit, where 1 px = 1 / 96 = 1/96 =1/96th of an inch. However, pixels are relative to the viewing device.
Should I avoid using px in CSS
The biggest issue with using px in our CSS are the font sizes and accessibility. A user can set their preferred font size for the browser. A bigger or smaller font size based on their vision needs. Also, the px units in CSS are not mapped to the old hardware pixels.
Should I use REM CSS
Why should you use rem units As mentioned before, rem units reference the size of the root element. Since a user can set the default size of this element from their browser settings, the webpage can scale to match a user's preference. Using absolute units like pixels, however, creates accessibility barriers.

Should I use rem for images
Use REMs for sizes and spacing. Use EMs for media queries. In summary, both pixels and REMs for media queries fail in various browsers when using browser zoom, and EMs are the best option we have. It's a better practice to use rem instead of pixels if you want a responsive website.

What is the best unit to set height CSS
Pixels are the most commonly used and accepted unit. And it's considered the base of measurement for many other units. It provides the most consistent result among various devices. The box element in the following example has a height of 150px and width of 150px, and it will remain the same on all screen sizes.
What is the best unit for height CSS
Viewport height (vh) unit – CSS viewport height refers to the height of the viewport. 1vh is equal to 1% of the viewport height. Viewport width (vw) unit – this unit refers to the width of the viewport. 1vw equals to 1% of the viewport width.
Should I use rem or px for font size
The relative unit, on the other hand, grows with the default settings of the browser. So this is really an accessibility concern. Therefore, any time you're defining font-sizes, you should absolutely (or relatively) use rems.
Is rem always 16 px
Rem (short for “root-em”) units dictate an element's font size relative to the size of the root element. By default, most browsers use a font size value of 16px. So, if the root element is 16px, an element with the value 1rem will also equal 16px.
Should I use rem or px for text
Pixels are an absolute unit, so when you set the font size to 24 pixels, it's going to be 24 pixels. Rems, on the other hand, are relative units that are based on the document's font-size. The document's default font size is 16 pixels, so 1.5rems x 16px is the equivalent of 24 pixels.
Is rem better for responsive design
em and rem meet web accessibility standards, and, unlike px , scale better. Consequently, they are more suited for responsive design.

How to get 100% height in CSS
To set an element's height equal to the screen's height, set its height value to 100vh. It's easy to break your layout doing this, and you'll need to be aware of which other elements will be impacted, but the viewport is by far the most direct way to set an element's height to 100% of the screen.
How do I make my height 100% in CSS
height:100vh
box class has only 100vh which is 100% of the viewport height. When you set the height to 100vh, the box element will stretch its height to the full height of the viewport regardless of its parent height.
Is 16px a good font size
While there is no official minimum font size for the web, it is generally agreed upon that 16px for body text is a good starting point. Of course, some text will be smaller and headings will often times be larger. But, the main body text (like what you're reading right now) should usually be 16px or larger.
