Should I use PT or PX?
Use em or px for font sizes

Should you use px in CSS?
Use px for very tiny sizes.
At very small sizes, pt can get blurry in some browsers at 96 DPI, since pt and px don’t quite line up. If you just want to create a thin, one-pixel border, say so.
Is PX the same as PT?
So 1 pt = 1/72 inch. Therefore, on a 72 ppi display, 1 point = 1 pixel. 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].
Is using PX bad?
Pixels are not that bad, I mostly use them too. (Sometimes even for font sizes.) … For a fixed-width layout, pixel values are fine. If a designer gives you a Photoshop image that contains really fancy stuff which would be extremely complicated to even think about how it would resize, you should definitely go for this.
What does PT mean in HTML?
The final unit of measurement that it is possible to declare font sizes in is point values (pt). Point values are only for print CSS! A point is a unit of measurement used for real-life ink-on-paper typography. 72pts = one inch.
What can I use instead of PX in CSS?
% is also a relative unit, in this case, relative to either the height or width of a parent element. They are a good alternative to px units for things like the total width of a design if your design does not rely on specific pixel sizes to set its size.
What Is REM in HTML?
To recap, the rem unit means “The root element’s font-size”.
(rem stands for “root em”.) The <li> elements inside the <ul> with a class of rems take their sizing from the root element ( <html> ). This means that each successive level of nesting does not keep getting larger.
How do you use REMS CSS?
rem values are relative to the root html element, not to the parent element. That is, If font-size of the root element is 16px then 1 rem = 16px for all elements. If font-size is not explicitly defined in root element then 1rem will be equal to the default font-size provided by the browser (usually 16px).

Why Is REM better than PX?
The reason headings often use em units is they’re a better choice than px units, being relative to regular text size. However rem units can achieve this goal equally well. If any font size adjustment on the html element is made, the heading sizes will still scale too.
Is PX the same as pixels?
The px unit got its name from those screen pixels. Nowadays there are devices that could in principle display smaller sharp dots (although you might need a magnifier to see them). But documents from the last century that used px in CSS still look the same, no matter what the device.
What Is REM vs em?
