sass-css-utilities - A SASS library for rapid frontend development.

Intro

The main aim of the library is to speedup up the website development process with the usage of simple utility classes. The utility classes can be used to modify web page elements in tablets and phones without needing to make any CSS changes.

It also contains a small set of useful SASS mixins.

Class names

All of the CSS classes support usage in phones and tables through media queries. You simply need to add the device category specific prefix to make them device specific. The default prefixes are: tab-, phn-tab-, phn- (These can be changed in config)

For example, For modifying the display property of a div in different devices:

<div class="block phn-inline-block">I will change to inline block when viewed on a phone</div>

Similarly for changing margin or padding:

<div class="pad-30 mar-60 tab-pad-20 tab-mar-40 phn-pad-10 phn-mar-20">My margin and padding will change in tablet and phone</div>

This is just a simple example. The classes can be used to modify even a single property like this:

<div class="pad-30 mt-60 phn-pv-20 phn-mt-20">My top margin and vertical padding will change in phone</div>

How to use

Just copy the directory to your project and import using:

@import "sass-css-utilities/sass-css-utilities";

If you want to change configuration, declare the configuration variables before importing the library. (In different file, or on top of import statement. Check style.scss for example)

• until-width($device-width) : Devices with max width as specified
• if-device($device) : Media query specific to a device. Possible values are tablet, phone-tablet and phone.

Device width config can be updated with these variables:

$scu-phone-max-width   : 767px;
$scu-tablet-min-width  : 768px;
$scu-tablet-max-width  : 979px;
$scu-desktop-min-width : 980px;

Example

@include at-least-width(1600px){
    // a wide screen device with width >= 1600px
}
@include until-width(979px){
    // phones and tablets (width <= 979px)
}
@include if-device(tablet){
    // tablet (min-width 768px and max width 979px)
}
@include if-device(phone-tablet){
    // phone or tablet (max-width 979px)

ml-a or ml-auto: auto value for left margin property

mr-a or mr-auto: auto value for right margin property

Auto generated margin classes:

Specify values of margins to be generated in variable $scu-margins and the library will automatically generate different cases based on these.

$scu-margins: (0 5 10 15 20)

Properties available are (where X is one of the values passed in $scu-margins

mar-X : Margin X. Eg: mar-5 is margin: 5px;

mt-X : Top Margin. Eg: mt-10 is margin-top: 10px;

mb-X : Bottom Margin. Eg: mb-10 is margin-bottom: 10px;

ml-X : Left Margin. Eg: ml-10 is margin-left: 10px;

mr-X : Right Margin. Eg: mr-10 is margin-right: 10px;

mv-X : Vertical Margin. Eg: mv-5 is margin-top: 5px; margin-bottom: 5px;

mh-X : Horizontal Margin. Eg: mh-5 is margin-left: 5px; margin-right: 5px;

Padding

Padding classes are also auto generated just like the margin classes.

pad-X : Padding X. Eg: pad-5 is padding: 5px;

pt-X : Top Padding. Eg: pt-10 is padding-top: 10px;

pb-X : Bottom Padding. Eg: pb-10 is padding-bottom: 10px;

Tablet and Mobile

All of these utility classes can be used with Device prefix technique. For example:

<div class="pad-40 align-center phn-pad-20 phn-pt-10 phn-align-left">Content</div>

This div will have 40px padding in desktop and 20px padding in phones. Additionally we have further changes the top padding to 10px in phone. Text align will be center in desktop and left in phone.

---

Configuration

!important in rules

By default all of the css properties defined in the utility classes have !important attribute to ensure that the classes work as expected by overiding values for the element. This can be disabled with these variable:

$scu-use-important: true; // For all classes. Default value is true
$scu-paddings-use-important: true; // For auto generated paddings
$scu-margins-use-important: true; // For auto generated margins

Prefixes

Default Global and device prefixes can be changed with these variables:

$scu-prefix:              "";
$scu-prefix-tablet:       "tab-";
$scu-prefix-phone-tablet: "phn-tab-";
$scu-prefix-phone:        "phn-";

Custom values for auto-generated margins and paddings

The classes to be generated can be specified in variables $config-paddings and $config-margins. The default values are:

$scu-paddings: (0 5 10 15 20 25 30);
$scu-margins:  (0 5 10 15 20 25 30);

You can even specify different values for vertical and horizontal classes. (Global as well as media cases) Check the config.scss file for all other config options and examples.

NOTE ON USAGE

These classes are meant to be used only for making minor changes in elements. Default values should always be specified in the css class or id of the element.
