**Prefix Constructor**

Utility macro that builds builds vendor prefixed versions of a statement.

Usage

Inside of you macro, call the prefix macro and pass it the following values in this order, as strings.
    CSS property to be prefixed
    Value: Any valid CSS value
    Prefixes: ms, webkit, moz, o (comma separated)
    Height: Optional, if not specified, width value will be used and triangle will have equal sides.

Example

{% macro exampleMacro %}
    {{ prefix('border-radius', '2px', "webkit") }}
{% endmacro %}

#}

{% macro prefix(property, value, prefixes) %}
    {% set prefixList = prefixes|split(",", 10) %}
    {% for prefix in prefixList %}
        -{{ prefix }}-{{ property }}: {{ value }};
    {% endfor %}
        {{ property }}: {{ value }};
{% endmacro %}


{#

**Rem Conversion Macro**

Safely and simply use rem values for all sizing and spacing.

Usage

Inside CSS block for an element, call macro with these parameters in this order:
    Property: Any valid CSS property, as a string
    Value: A pixel value or values without unit suffix (15 not 15px)

Note

Values assume CSS convention. You can use from 1 to 4 values seperated by spaces.
If you use more than 4, nothing will be returned.
If you use more values than a property can accept, your CSS rule will be invalid.

Example

.my-selector{
    {{ remConversion('font-size', '20') }}
    {{ remConversion('letter-spacing', '.2') }}
    {{ remConversion('padding', '10 25 5 50') }}
}


#}





{% macro rem(property, value) %}

    {%if !baselineFontSize %}{% set baselineFontSize = 16 %}{% endif %}

    {% if (property|length > 0) and (value|length == 0) %}

        {% set values = property|split(' ') %}
        {% for v in values %}
            {% if v|float == 0 %}
                {% set remValue = v %}
            {% else %}
                {% set remValue = v/baselineFontSize %}
            {% endif %}
            {% set remArray = remArray ~ remValue ~"," %}
            {% if loop.last %}
                {% set remArray = remArray|split(',', 9) %}
                {% for x in remArray %} {{ x }}{% if x|float != 0 %}rem{% endif %}{% endfor %}
            {% endif %}
        {% endfor %}

    {% else %}

        {% set values = value|split(' ') %}
        {% for v in values %}
            {% if v|float == 0 %}
                {% set remValue = v %}
            {% else %}
                {% set remValue = v/baselineFontSize %}
            {% endif %}
            {% set pxArray = pxArray ~ v ~"," %}
            {% set remArray = remArray ~ remValue ~"," %}
            {% if loop.last %}
                {% set pxArray =  pxArray|split(',', 9) %}
                {% set remArray = remArray|split(',', 9) %}
                {{ property }}:{% for x in pxArray %} {{ x }}{% if x|float != 0 %}px{% endif %}{% endfor %};
                {{ property }}:{% for x in remArray %} {{ x }}{% if x|float != 0 %}rem{% endif %}{% endfor %};
            {% endif %}
        {% endfor %}

    {% endif %}

{% endmacro %}


{#

**Em Conversion Macro**

Simple converter for switching pixel values to ems

Usage

On the assignment side of any appropriate CSS property,
call the macro and pass it these parameters in this order:
    Value: A pixel value or values without unit suffix (15 not 15px)
    Context: Optional. Defaults to 16. Override if using on nested elements. See notes.

Notes

We recommend using Rems as the default measurement unit. See Rem Conversion macro for more details.
If you use this macro on many nested elements, we strongly recommend a comment and/or indenting convention
to keep track of context.
Values assume CSS convention. You can use from 1 to 4 values seperated by spaces.
If you use more than 4, nothing will be returned.
If you use more values than a property can accept, your CSS rule will be invalid.

Examples

#em-example{
    font-size: {{ emConversion('25') }};
}

#em-example2{
    padding: {{ emConversion('25 10', '18') }};
}


#}


{% macro em(value, context) %}

    {%if !context %}{% set context = 16 %}{% endif %}

    {% set values = value|split(' ') %}
    {% for v in values %}
        {% set emValue = v/context %}
        {% set emArray = emArray ~ emValue ~"," %}
        {% if loop.last %}
            {% set emArray = emArray|split(',', 9) %}
            {% for x in emArray %} {{ x }}em{% endfor %};
        {% endif %}
    {% endfor %}


{% endmacro %}


{#

**Box Shadow**

#}


{% macro boxShadow(shadow) %}
{{ prefix('box-shadow', shadow, "webkit") }}
{% endmacro %}


{#

** Vertical and Horizontal Centering Macro **

Uses the Ghost Vertical Alignment technique to center elements in their container

Usage

Call macro anywhere in CSS with these parameters in this order:
    Container: CSS selector for parent of element you'd like to center
    Element: CSS selector for element you'd like to center

Note

See: https://css-tricks.com/centering-in-the-unknown/ for original technique

#}

{% macro verticalAndHorizontalCenter(container, element) %}

    {{ container }}{
        text-align: center;
    }
    {{ container }}:before{
        content: '';
        display: inline-block;
        height: 100%;
        vertical-align: middle;
        /* offset horizontal spacing */
        margin-right: -0.25em;
    }
    {{ element }}{
        display: inline-block;
        vertical-align: middle;
    }

{% endmacro %}


{#

**Position Macro**

Use shorthand for positioning.

Usage

Inside CSS block for element you'd like to position, call macro with these parameters in this order, all strings.
    Position: Valid CSS position (absolute, relative, fixed, static)
    Top, Right, Bottom, Left (standard order for shorthand CSS properties)

Note

Use 'null' for any value you would like to exclude. The position property is required.

Example

 {{ position('absolute', null, '0', '0', null) }};

#}

{% macro position(position, top, right, bottom, left) %}

    position: {{ position }};

    {% if top %}
        top: {{ top }};
    {% endif %}
    {% if right %}
        right: {{ right }};
    {% endif %}
    {% if bottom %}
        bottom: {{ bottom }};
    {% endif %}
    {% if left %}
        left: {{ left }};
    {% endif %}

{% endmacro %}


{#

**Clearfix Macro**

Short, easy, clearfix.

Usage

Call macro anywhere in CSS with selector(s) you'd like to clear.

Notes

Using this macro once and adding all selectors to it will reduce the size of your stylesheets
and is therefore recommended if possible

This macro uses the :after pseudo class. Using it for other purposes on elements using this macro will
likely break the clear.

Example

{{ clearfix('.my-div') }};

or

{{ clearfix('.my-div, .other-div, .more-divs') }};

#}

{% macro clearfix(selector) %}

  {{ selector }}:after {
    content: "";
    display: table;
    clear: both;
  }

{% endmacro %}


{#

**Arrow Macro**

Draw an arrow with CSS. Direction, color and size are all variable.

Usage

Inside CSS block for element that should be an arrow, call macro with these parameters in this order, all strings.
    Direction: top, right, bottom, left
    Color: Any valid CSS value
    Width: Any valid CSS measurement.
    Height: Optional, if not specified, width value will be used and triangle will have equal sides.

Note

This technique is commonly used on :before or :after pseudo elements. If using this way, be sure to add the content property
in your CSS rule. It is not included in this macro.

Example

{{ arrow('top','#333','2em', '5em') }}

#}


{% macro arrow(direction, color, width, height) %}

    display: block;
    height: 0;
    width: 0;

    {%if !height %}{%set height = width%}{%endif%}

    {% if direction == 'top' %}
        border-left: {{ width }} solid transparent;
        border-right: {{ width }} solid transparent;
        border-bottom: {{ height }} solid {{color}};
    {% elif direction == 'right' %}
        border-top: {{ width }} solid transparent;
        border-bottom: {{ width }} solid transparent;
        border-left: {{ height }} solid {{color}};
    {% elif direction == 'bottom' %}
        border-top: {{ height }} solid {{color}};
        border-right: {{ width }} solid transparent;
        border-left: {{ width }} solid transparent;
    {% elif direction == 'left' %}
        border-top: {{ width }} solid transparent;

{#########################################

## HubSpot Helper Macros ##

#########################################}

**Prefix Constructor**

Utility macro that builds builds vendor prefixed versions of a statement.

Usage

Inside of you macro, call the prefix macro and pass it the following values in this order, as strings.

CSS property to be prefixed

Value: Any valid CSS value

Prefixes: ms, webkit, moz, o (comma separated)

Height: Optional, if not specified, width value will be used and triangle will have equal sides.

Example

{% macro exampleMacro %}

{% endmacro %}

{% macro prefix(property, value, prefixes) %}

{% set prefixList = prefixes|split(",", 10) %}

{% for prefix in prefixList %}

-{{ prefix }}-{{ property }}: {{ value }};

{% endfor %}

{{ property }}: {{ value }};

{% endmacro %}

**Rem Conversion Macro**

Safely and simply use rem values for all sizing and spacing.

Usage

Inside CSS block for an element, call macro with these parameters in this order:

Property: Any valid CSS property, as a string

Value: A pixel value or values without unit suffix (15 not 15px)

Note

Values assume CSS convention. You can use from 1 to 4 values seperated by spaces.

If you use more than 4, nothing will be returned.

If you use more values than a property can accept, your CSS rule will be invalid.

Example

.my-selector{

}

{% macro rem(property, value) %}

{%if !baselineFontSize %}{% set baselineFontSize = 16 %}{% endif %}

{% if (property|length > 0) and (value|length == 0) %}

{% set values = property|split(' ') %}

{% for v in values %}

{% if v|float == 0 %}

{% set remValue = v %}

{% else %}

{% set remValue = v/baselineFontSize %}

{% endif %}

{% set remArray = remArray ~ remValue ~"," %}

{% if loop.last %}

{% set remArray = remArray|split(',', 9) %}

{% for x in remArray %} {{ x }}{% if x|float != 0 %}rem{% endif %}{% endfor %}

{% endif %}

{% endfor %}

{% else %}

{% set values = value|split(' ') %}

{% for v in values %}

{% if v|float == 0 %}

{% set remValue = v %}

{% else %}

{% set remValue = v/baselineFontSize %}

{% endif %}

{% set pxArray = pxArray ~ v ~"," %}

{% set remArray = remArray ~ remValue ~"," %}

{% if loop.last %}

{% set pxArray = pxArray|split(',', 9) %}

{% set remArray = remArray|split(',', 9) %}

{{ property }}:{% for x in pxArray %} {{ x }}{% if x|float != 0 %}px{% endif %}{% endfor %};

{{ property }}:{% for x in remArray %} {{ x }}{% if x|float != 0 %}rem{% endif %}{% endfor %};

{% endif %}

{% endfor %}

{% endif %}

{% endmacro %}

**Em Conversion Macro**

Simple converter for switching pixel values to ems

Usage

On the assignment side of any appropriate CSS property,

call the macro and pass it these parameters in this order:

Value: A pixel value or values without unit suffix (15 not 15px)

Context: Optional. Defaults to 16. Override if using on nested elements. See notes.

Notes

We recommend using Rems as the default measurement unit. See Rem Conversion macro for more details.

If you use this macro on many nested elements, we strongly recommend a comment and/or indenting convention

to keep track of context.

Values assume CSS convention. You can use from 1 to 4 values seperated by spaces.

If you use more than 4, nothing will be returned.

If you use more values than a property can accept, your CSS rule will be invalid.

Examples

#em-example{

font-size: {{ emConversion('25') }};

}

#em-example2{

padding: {{ emConversion('25 10', '18') }};

}

{% macro em(value, context) %}

{%if !context %}{% set context = 16 %}{% endif %}

{% set values = value|split(' ') %}

{% for v in values %}

{% set emValue = v/context %}

{% set emArray = emArray ~ emValue ~"," %}

{% if loop.last %}

{% set emArray = emArray|split(',', 9) %}

{% for x in emArray %} {{ x }}em{% endfor %};

{% endif %}

{% endfor %}

{% endmacro %}

**Box Shadow**

Add drop shadows to your HTML elements.

Usage

Inside CSS block for element that should have a drop shadow, call macro with standard box-shadow parameters.

h-shadow v-shadow blur spread color

Example

{% macro boxShadow(shadow) %}

{% endmacro %}

** Vertical and Horizontal Centering Macro **

Uses the Ghost Vertical Alignment technique to center elements in their container

Usage

Call macro anywhere in CSS with these parameters in this order:

Container: CSS selector for parent of element you'd like to center

Element: CSS selector for element you'd like to center

Note

See: https://css-tricks.com/centering-in-the-unknown/ for original technique

{% macro verticalAndHorizontalCenter(container, element) %}

{{ container }}{

text-align: center;

}

{{ container }}:before{

content: '';

display: inline-block;

height: 100%;

vertical-align: middle;

/* offset horizontal spacing */

margin-right: -0.25em;

}

{{ element }}{

display: inline-block;

vertical-align: middle;

}

{% endmacro %}

**Position Macro**

Use shorthand for positioning.

Usage

Inside CSS block for element you'd like to position, call macro with these parameters in this order, all strings.

Position: Valid CSS position (absolute, relative, fixed, static)

Top, Right, Bottom, Left (standard order for shorthand CSS properties)

Note

Use 'null' for any value you would like to exclude. The position property is required.

Example

{{ position('absolute', null, '0', '0', null) }};

{% macro position(position, top, right, bottom, left) %}

position: {{ position }};

{% if top %}

top: {{ top }};

{% endif %}

{% if right %}

right: {{ right }};

{% endif %}

{% if bottom %}

bottom: {{ bottom }};

{% endif %}

{% if left %}

left: {{ left }};

{% endif %}

{% endmacro %}

**Clearfix Macro**

Short, easy, clearfix.

Usage

Call macro anywhere in CSS with selector(s) you'd like to clear.

Notes

Using this macro once and adding all selectors to it will reduce the size of your stylesheets

and is therefore recommended if possible

This macro uses the :after pseudo class. Using it for other purposes on elements using this macro will

likely break the clear.

Example

{{ clearfix('.my-div') }};

{{ clearfix('.my-div, .other-div, .more-divs') }};

{% macro clearfix(selector) %}

{{ selector }}:after {

content: "";

display: table;

clear: both;

}

{% endmacro %}

**Arrow Macro**

Draw an arrow with CSS. Direction, color and size are all variable.

Usage

Inside CSS block for element that should be an arrow, call macro with these parameters in this order, all strings.

Direction: top, right, bottom, left

Color: Any valid CSS value

Width: Any valid CSS measurement.

Height: Optional, if not specified, width value will be used and triangle will have equal sides.

Note

This technique is commonly used on :before or :after pseudo elements. If using this way, be sure to add the content property

in your CSS rule. It is not included in this macro.

Example

{% macro arrow(direction, color, width, height) %}

display: block;

height: 0;

width: 0;

{%if !height %}{%set height = width%}{%endif%}

{% if direction == 'top' %}

border-left: {{ width }} solid transparent;

border-right: {{ width }} solid transparent;

border-bottom: {{ height }} solid {{color}};

{% elif direction == 'right' %}

border-top: {{ width }} solid transparent;

border-bottom: {{ width }} solid transparent;

border-left: {{ height }} solid {{color}};

{% elif direction == 'bottom' %}

border-top: {{ height }} solid {{color}};

border-right: {{ width }} solid transparent;

border-left: {{ width }} solid transparent;

{% elif direction == 'left' %}

border-top: {{ width }} solid transparent;

border-right: {{ height }} solid {{color}};

border-bottom: {{ width }} solid transparent;

{% endif %}

{% endmacro %}

**Linear Gradient Macro**

Use standards gradient notation and get webkit fallback as well

Usage

Inside CSS block for an element, call macro with these parameters in this order:

Direction: Gradient direction. Use standard syntax ('to top', '190deg', etc). Macro will convert for webkit prefixed rule

Stops: Any standard stops. They will be passed along directly, refer to documentation for correct syntax

Examples

#gradient {

}

#gradient {

{{ linearGradient('190deg', 'rgba(200, 200, 190, 1) 20%, rgba(200, 200, 190, 0) 80% ') }}

}

{% macro linearGradient(direction, stops) %}

{% set directions = {'to top' : 'bottom', 'to top right': 'bottom left', 'to right top' : 'left bottom', 'to right' : 'left', 'to bottom right' : 'top left', 'to right bottom' : 'left top', 'to bottom' : 'top', 'to bottom left' : 'top right', 'to left bottom' : 'right top', 'to left' : 'right', 'to left top' : 'right bottom', 'to top left' : 'bottom right'} %}

{% if direction is defined %}

{% set deg = direction|cut('deg') %}

{% if deg|int or deg == '0' %}

{% set ld = 90 - deg ~ 'deg, ' %}

{% else %}

{% set ld = directions[direction] ~ ', ' %}

{% endif %}

{% set d = direction ~ ', ' %}

{% endif %}

background: -webkit-linear-gradient({{ld}}{{stops}});

background: linear-gradient({{d}}{{stops}});

{% endmacro %}
