td-scss

A small collection mixins, variables and animations which address common concerns in my projects.

Colours

Base colours are exported as variables, core pallete conisists of [$green, $yellow, $red, $purple, $aqua, $orange]. There are 5 shades of each also exported through a palette function which takes a colour and a shade, the default variables are the "base" 300 shade.

"shade" is a number between 100 (being the lightest), to 500 (being the darkest).

i.e palette(green, 200);

additional colour options for:

• background: [$bg, $bg-dim, $bg-current-word, $bg-[0-4]] (0 being darkest through to 4 the lightest).
• greys: [$grey-[0-4]]: (0 being the darkest through to 4 being the lightest).
• foreground: [$fg, $fg-[0-5]] (0 being the lightest and 5 being the darkest).
• diffs: All vars prefixed with $bg-diff-: [green, green-soft, red, red-soft, blue, blue-soft, yellow-soft].

Mixins

breakpoints

Exported breakpoint variables exclude:

• $width-small-mobile: 370px
• $width-mobile: 640px;
• $width-tablet: 768px
• $width-desktop: 1024px
• $width-expanded: 1536px

common breakpoint media query mixins:

| name | query | | -------------------- | --------------------------------------------------------------------------------- | | mobile | @media (max-width: #{$width-tablet - 1px}) | | small-mobile | @media (max-width: #{$width-small-mobile}) | | max-portrait-mobile | @media (max-width: #{$width-mobile - 1px}) | | max-landscape-mobile | @media (max-width: #{$width-tablet - 1px}) | | tablet | @media (min-width: #{$width-tablet}) and (max-width: #{$width-desktop - 1px}) | | min-tablet | @media (min-width: #{$width-tablet}) | | max-tablet | @media (max-width: #{$width-desktop - 1px}) | | desktop | @media (min-width: #{$width-desktop}) and (max-width: #{$width-expanded - 1px}) | | min-desktop | @media (min-width: #{$width-desktop}) | | max-desktop | @media (max-width: #{$width-expanded - 1px}) | | expanded | @media (min-width: #{$width-expanded}) |

theme

A mixin for generating theme based classes. It requires a color argument and will generate four classes ([primary, secondary, tertiary, quarternary]) of varying colours from the provided theme. You can optionally specify rotate and darkenpct arguments for more control over the generated theme.

Example usages:

.theme-1 {
  @include theme(green);
}
.theme-2 {
  @include theme(yellow, 90deg);
}
.theme-3 {
  @include theme(yellow, 180deg, 40%);
}
.theme-4 {
  @include theme(purple, $darkenpct: 10%);
}

The mixin works by rotating the colour wheel at certain angles to pick complimentary colours. It uses relative luminance to select the text color to keep a nice contrast that's still easy to read.

relative luminance

This was an interesting rabbit hole to fall into. Relative lumincance is described as the relative brightness of any point in colour space. So this mixin is used for setting text colour on elements when we don't know what the background colour will be.

Example usages:

// get the lumiance value of white
$white_luminance: luminance(#fff);
.btn {
  // set the dark text colour
  color: #000;

  // compare relative brightness of our "unknown" colour against white
  @if abs(luminance($color) - $white_luminance) > 0.7 {
    color: #eee;
  }
}

btn

Base button styles for solid, outline and link variants:

.primary-button {
  @include btn-solid($colour);
}
.secondary-button {
  @include btn-outline($colour);
}
.link {
  @include btn-link($colour);
}

Animations

pop

slight increase in scale temporarily, primarily design for hover interactions. Takes optional size and duration arguments.

Example usage:

.item {
  @include pop();
}
.item-1 {
  @include pop(1.1, 300ms);
}
.item-2 {
  @include pop($duration: 300ms, $size: 1.3);
}

shake

quick horizontal shake, good for errors/invalid actions. Takes an optional duration agument.

Example usage:

.item {
  @include shake();
}
.item-1 {
  @include shake(100ms);
}
