Is it better to use em or px?

The answer used to be absolutely yes because, if you used px units, you prevented the text from being resized by the user at all. But browser zoom is the default method for making everything bigger (including text) these days and it works great even if you use px .

Should I use REM or em or px?

I recommend using rem units for fonts, if only because it makes it easier for you, the developer, to change sizes. It’s true that users very rarely change the default font size in their browsers, and that modern browser zoom will scale up px units.

Is em bigger than px?

The em and ex units depend on the font and may be different for each element in the document. The em is simply the font size. The px unit is the magic unit of CSS. It is not related to the current font and usually not related to physical centimeters or inches either.

Should you use em or REM?

Use EM where you have to make more scaling than the root font size. And use REM where you need value according to the root there you can use REM units.

Should we use em or REM?

While em is relative to the font-size of its direct or nearest parent, rem is only relative to the html (root) font-size. Jeremy tends to favor em , because of the ability to control an area of a design. As in, scale the type in that specific area relatively.

Should I use VW or em?

VW is viewport width (the visible size of the window) and em is the width of the letter ‘m’ in the current font. So 5vh is 5% of the viewport and 5em is the width of 5 ‘m’s. @Zikooz You would probably be best using em or more specifically, rem for the ROOTem.

What is the difference between REM and em and px?

Pixel ( px ) is a commonly used CSS unit on websites. px is not scalable, it is an absolute unit. Change in the value of another element does not affect the value of absolute units. Element ( em ) and Root element ( rem ) are responsive units interpreted into equivalent px unit by the browser.

Should I use REM for margin and padding?

Don’t use rem/em for paddings, margins and more.

What is difference between PX and PT in CSS?

A pt is 1/72 of an in, and a px is 1/96 of an in. A px is therefore 0.75 pt [source]. In CSS, everything is somewhat abstracted, so a unit such as a “pt” is not necessarily one point in physical size, especially on a screen, an “in” is not necessarily one inch in size, and so forth.

Should I use VH or REM?

Rem: Rem is relative to the font size of the root element (html element). If you want to size your element based on the viewport width and not the parent element/root element, then viewport units is the font sizing unit you need to use. vw/vh units work great with typography and are commonly used for the same.

What is the difference between px em REM and VH in CSS?

While PX, EM, and REM are primarily used for font sizing, %, VW, and VH are mostly used for margins, padding, spacing, and widths/heights. To reiterate, VH stands for “viewport height”, which is the viewable screen’s height. 100VH would represent 100% of the viewport’s height, or the full height of the screen.
