What they can do is help you achieve a harmonious and balanced design. Users won't be able to increase the font size in those browsers. Most recommend a line-height of 1. Millimeters, centimeters and inches are inaccurate for a screen-based medium. Legend Full support Full support No support No support Compatibility unknown Compatibility unknown See implementation notes. Just change the base font size everything will change.
Both Standards and Quirks modes are supported in A-grade browsers. Default value: The default value of the font properties Inherited: yes Animatable: yes, see individual properties. Em Units The main problem with em units is that they are relative to the font size of their own element. If the content is larger than the minimum width, the min-width property has no effect. Just like in the previous section, the purpose is to customize the reading experience for the device used. There is obviously a compromise between them.
Any insight as to why this has been left out of the spec? In previous one you could just change the body font and not h1 every time or let base font size to default of the device and rest all in em see for more info on em, px and % The only way would probably be to set different widths for different screen sizes, but this approach is pretty inacurate and you should use a js solution. You don't have to change each rule, just the html element and fine tune what's necessary. When the browser window is resized, the font doesn't adjust itself according to the new viewport size. I often encounter responsive websites which scale down the paragraph font-size to 14px or even less in the mobile layout. While you can set a base font size on body using the font-size property, anything after that that specifies a smaller size will override the base rule for that element.
Rule of thumb: The closer the device will probably be and the higher the pixel density the smaller should the font be. Hopefully it is of use to others reading this article. For low-dpi devices, 1px is one device pixel dot of the display. Will we have very small font? It can be assigned a variety of absolute, relative, or length size parameters. You can use them on anything, not just font-size. Most websites today use font sizes ranging between 14 and 18 pixels for body text.
On large screens, this technique will make reading hard very quickly. Will 1vh be 1% of the screen height, or the viewport height? They're the units associated with setting the viewport width.

Louis Lazaris discussed that latter concept in.
I find that if I use vw, then as I alter only the height of the viewport, then the size of the font does not change until I change the width of the viewport , and vice versa for using vh and altering only the width of the viewport. I wanted to make a visual representation of how each set of sizes would overlap so we could make educated adjustments to the fluid portions and their overlaps to have the best experience possible, so I made the following CodePen. Text Sizing and Page Zooming This is where additional complexity creeps in. The end result is that vw units don't take advantage of the viewport size adjustment made by mobile device browsers. Safari No support No WebView Android? Joseph Silber is wrong, coding all the possibilities actually is a viable way to do this.
But already the first point should be reason enough to never use it for font size settings. Just to complicate matters further, Internet Explorer does not allow text resizing on elements which have a font size defined in pixels px. Do Viewport Units for Responsive Font Size Make Sense? Even better allow the user to set a size and remember it for their next use - they still might change it but it is more likely to be correct than any size the developer would choose. It also applies to and. A book-like device with a theoretical 300 dpi held closely might actually ask for fonts. However, as we saw earlier, it is very easy to lose track of nesting and get unexpected results with em units.
