Ok, I assume, given that paragraph above (a quote from somewhere on the
internets?, source?), I assume you are trying to understand what the following
means:
.myclass { font-size: calc( 2.2em + 2.2vw); }
1. calc() means: calculate the sum of the following two values.
2. 2.2em - converted a pixel size, assuming 16px base font: 16 * 2.2 = 35.2px.
3. 2.2vw - here is where it gets interesting: `vw` stands for viewport width,
1vw = 1% of the viewport width.
Let’s assume a 1000px wide viewport / window, then 2.2vw * 1000px/100 = 2.2
* 10 = 22px
Thus: calc( 2.2em + 2.2vw) = 35.2px + 22px = 57.2px
3b. Now resize the window, let’s assume the viewport / window is 500px wide;
2.2 * 500/100 = 2.2 * 5 = 11px. In this case, the font-size will be 35.2px +
11px = 46.2px.
