What is a CSS lock?
A CSS lock is a technique used to smooth change the font size depending on viewport width between to breakpoints.
How to use?
Add the mixin in your SCSS file and use @include to include it to where you want it to be used.
@include scss-font-lock($min-size, $max-size, $min-width, $max-width);Change the variables to desired values in either px or em. Please not that the output will be presented in px. The mixin contains a calculation of em to px with the default font-size of 16px. However, you can change that base value by include another variable in the mixin with the new value. Example:
@include scss-font-lock($min-size, $max-size, $min-width, $max-width, 14px);Example
This example demonstrate a CSS lock where the font size will be 16px up to a vieport width of 375px and then scale up to 60px which locks at 1024px:
@include scss-font-lock(16px, 60px, 375px, 1024px);Variables
| Variable | Description |
|---|---|
| $min-size | Font minimum size. Will be displayed on viewport smaller than $min-width. |
| $max-size | Font maximum size. Will be displayed on viewport larger than $max-width. |
| $min-width | Breakpoint where the font reaches its minimal font size. |
| $max-width | Breakpoint where the font reaches its maximum font size. |
| $base-font-size | Optional. Base font size used to calculate values set in em. Default 16px if not passed into the mixin. |
Error handling
This mixin is built to handle errors. If variables are set it non-compatible units, it will let you know when you compile into css using SCSS @warn. Another feature is that the mixin will ignore an output on error and instead display an error message on top of the text.
