Create a CSS mixin for calculating REM values that is not specific to font sizing or any particular element

Hello everyone! I have the following mixin and I am looking to make it a global one. What I mean is, without setting the margin, I want to use it for font-size for example, or for anything else that you might want to set into rem/em units. I am new to Less and preprocessors, so I was wondering if someone here could help me change the code. Thank you very much for your time.

.marginSizeCalc(@sv) {
  @sizeValue: unit(@sv);
  @remValue: (@sizeValue / @font-size-base);
  margin: unit(@sv, px);
  margin: unit(@remValue, rem);
}

Answer №1

Discovered a solution to the issue... and I believe it surpasses simply adjusting margin or font within the mixin.

.marginSizeCalc(@sv) {
  @sizeValue: unit(@sv);
  @remValue: (@sizeValue / @font-size-base);
  @toRem: unit(@remValue, rem);
}

Instructions:

h1, h2, h3, h4, h5, h6 {
    font-family: @headings-font-family;
    font-weight: @headings-font-weight;
    color: @headings-font-color;
    margin: @remValue;
    margin: @toRem;
    .marginSizeCalc(@gutterWidth);
}

Revision:

.marginSizeCalc(@sv, @db) {
  @sizeValue: unit(@sv);
  @divideBy: unit(@sv);
  @remValue: (@sizeValue / @divideBy);
  @toPx: unit(@remValue, px);
  @toRem: unit(@remValue, rem);
}

h1, h2, h3, h4, h5, h6 {
    font-family: @headings-font-family;
    font-weight: @headings-font-weight;
    color: @headings-font-color;
    margin: @toPx;
    margin: @toRem;
    .marginSizeCalc(@gutterWidth, 2);
}
