Brightspot Styleguide

All the rules and guidelines in https://github.com/perfectsense/brightspot apply to this repository as well. This is separated out only because npm doesn't allow linking to a subdirectory (npm/npm#2974).

    </div>
{{/block}}

How do I rename it?

{{block "MyPromo" override="Promo.hbs"}}

How do I reorder or remove elements?

{{#block "MyPromo" override="Promo.hbs"}}
    {{#blockBody}}
        {{element "figure"}}
        {{element "title"}}
    {{/blockBody}}
{{/block}}

{{#block "MyPromo" override="Promo.hbs"}}
    {{#element "caption"}}
        <div class="{{elementName}}">{{this}}</div>
    {{/element}}
{{/block}}

How do I change the outer block markup?

{{#block "MyPromo" extend="Promo.hbs"}}
    <section class="{{blockName}}">{{blockBody}}</section>
{{/block}}

Styling Components

The default style of a component should be mobile first.

Styling Usage Examples

Where should I define media queries?

Within a MediaQueries.less file imported from All.less

Given: Promo.less:

.Promo {
  &-title {
    color: dodgerblue;
  }
}

How do I define a small and large size?

.Promo--small() {
  &-title {
    font-size: 10px;
  }
}

.Promo--large() {
  &-title {
    font-size: 20px;
  }
}

How do I default it to the small size?

.Promo {
  &-title {
    color: dodgerblue;
  }

  .Promo--small;
}

How do I change to the large size at a specific breakpoint?

Use media queries within your MediaQueries.less file:

@media "only screen and (min-width: 768px)" {
  .Promo {
    .Promo--large;
  }
}

How do I change to the large size only when it's a child of the right-rail?

Use container queries within your RightRail.less file:

.RightRail {
  .Promo {
    .Promo--large;
  }
}

Troubleshooting

IFrame not resizing properly: If you change your viewport width and the iframe doesn't resize to the content correctly, this is most likely due to an element height within the iframe, usually the html or body, set at 100% in the CSS. To avoid this discrepant behavior, make sure the element height is set to auto.
