Dynamic Resizing of Elements to the Window Size

You may often encounter situations where you are tasked with making elements that dynamically resize with the viewing window. Here is a simple way to accomplish dynamic element resizing with CSS.

CSS Code with Fixed Size

Here is a CodePen project with a fixed text size, for example:

h1 {
	font-family: arial;
	text-align: center;
	font-size: 72pt:
}

Notice how, as the window resizes, the text does not resize, and it even gets moved around to accommodate the smaller viewing window.

Simple Solution for Dynamic Resizing

One solution may be to use media tags with min-widths to change the text size, but that creates steps between various window sizes where the text size does not dynamically change until the window is a certain size.

The easiest way to achieve dynamic resizing is to use “vw”, “vh”, “vmin”, or “vmax” as your size unit. Short for “viewport’s width,” “viewport’s height,” “viewport’s smaller dimension,” and “viewport’s larger dimension,” this unit uses a percentage of some dimension of the viewing window and applies it to whatever CSS attribute you are using it on, even as the window’s size changes.

CSS Code For Dynamic Resizing

Here’s the same example, but instead of using “72pt” for the font size, we are using “5vw”. Notice that now, the font size changes with the size of the window.

h1 {
	font-family: arial;
	text-align: center;
	font-size: 5vw:
}
