## Stellar is a LESS library for easy and fast webapp scaffolding. | ||
|
||
**It is good at:** | ||
|
||
* vertical align; | ||
* and..centering of everything; | ||
* arranging in rows (for wide screens) and columns (for small screens); | ||
and of course | ||
* responsive design with just a few lines of code. | ||
|
||
**And easy because:** | ||
|
||
there is a **parent** (element) and it has **children** (elements)..and the parent says how his children are arranged in terms of x-axis and y-axis. | ||
|
||
|
||
### How to use: | ||
|
||
|
||
*First, let's see what the parent can do to children.* | ||
|
||
|
||
Use ``.row();`` or ``.column();`` on a parent element to arrange its children in a row or a column. | ||
|
||
Inside the brackets you can use ``@x:`` and ``@y:`` to specify how the children are positioned on the corresponding axis. | ||
|
||
Use ``@left;``, ``@center;``, ``@right;`` or ``@spread;`` for x-axix positioning. | ||
Use ``@top;``, ``@center;``, ``@bottom;`` or ``@spread;`` for y-axis positioning. | ||
|
||
|
||
**Default values:** | ||
|
||
.row(@x: @left; @y: @top;); | ||
.column(@x: @left; @y: @top); | ||
|
||
If using a default value, the property and its corresponding value can be skipped. | ||
|
||
**Sample:** | ||
|
||
Тhis: ``.row(@x: center; @y: @top);`` is the same like ``.row(@x: center;);``. | ||
|
||
|
||
*And now, what children can do despite their parent's say.* | ||
|
||
|
||
A child can get a different positioning than the rest of the children. | ||
|
||
Use ``.odd(row; @y: value;);`` when the children are arranged in a ``.row;``. | ||
(values ``@top``, ``@center``, ``@bottom``). | ||
|
||
Use ``.odd(column; @x: value;);`` when the children are arranged in a ``.column;``. | ||
(values: ``@left``, ``@center``, ``@right``). | ||
|
||
|
||
**Default values:** | ||
|
||
.odd(row; @y: @top;); | ||
.odd(column; @x: @left;); | ||
|
||
|
||
|
||
## Sample | ||
|
||
|
||
**HTML code** | ||
|
||
<div class="container-1"> | ||
<div class="child"></div> | ||
<div class="child"></div> | ||
<div class="child naughty"></div> | ||
<div class="child"></div> | ||
</div> | ||
|
||
|
||
**LESS code** | ||
|
||
.container-1 { | ||
.row(@x: @center; @y: @top); | ||
height: 100vh; | ||
width: 960px; | ||
.child { | ||
height: 100px; | ||
margin: 20px; | ||
width: 100px; | ||
} | ||
.naughty { | ||
.odd(row; @y: @center;); | ||
} | ||
} | ||
|
