Lethalin's is designed around a 24 column based system. It was built to scale with mobile-design first. The syntax for creating responsive columns is simple:
<div class="grid">
<div class="column">
<div class="example-column">
.column
</div>
</div>
</div>
The .grid class holds all the columns together. It has a default max-width of 1000px, which can be changed easily. Anything smaller than 1000px retains a responsive width and height.
The syntax for multiple columns is just as simple:
<div class="grid">
<div class="column sm-12">
<div class="example-column">
.column .sm-12
</div>
</div>
<div class="column sm-12">
<div class="example-column">
.column .sm-12
</div>
</div>
</div>
Lethalin uses 3 different sizes for responsive columns: .sm-#, .md-# and .lg-#
<div class="grid">
<div class="column sm-12 md-6">
<div class="example-column">
.column .sm-12 .md-6
</div>
</div>
<div class="column sm-12 md-6">
<div class="example-column">
.column .sm-12 .md-6
</div>
</div>
<div class="column sm-12 md-6">
<div class="example-column">
.column .sm-12 .md-6
</div>
</div>
<div class="column sm-12 md-6">
<div class="example-column">
.column .sm-12 .md-6
</div>
</div>
</div>
Multiple sized columns can also be stacked:
<div class="grid">
<div class="column sm-12 md-6">
<div class="example-column">
.column .sm-12 .md-6
</div>
</div>
<div class="column sm-12 md-6">
<div class="example-column">
.column .sm-12 .md-6
</div>
</div>
<div class="column sm-12 md-6">
<div class="example-column">
.column .sm-12 .md-6
</div>
</div>
<div class="column sm-12 md-6">
<div class="example-column">
.column .sm-12 .md-6
</div>
</div>
</div>
Also remember that when not supplying a .sm-# class, .column will treat itself as a 24-width column.
<div class="grid">
<div class="column md-12">
<div class="example-column">
.column .md-12
</div>
</div>
<div class="column md-12">
<div class="example-column">
.column .md-12
</div>
</div>
</div>
Adding the .wide utility class to any .grid object will set your grid to a maximum width of 1200px
<div class="grid wide">
<div class="column">
<div class="example-column">
.column .md-12
</div>
</div>
</div>
Navigation markdown is very simple
<header>
<div class="grid">
<a href="#" class="header">
Website Logo
</a>
<div class="navbar">
<a class="navbar-open"></a>
<ul class="nav-expand">
<li><a href="#intro">Intro</a></li>
<li><a href="#code">Code</a></li>
<li><a href="#demo">Demos</a></li>
</ul>
</div>
</div>
</header>
You can give your header the .sticky class to create a fixed header, just make sure to give your body a corresponding margin-top.
<header class="sticky">
Anchor Button's can be styled into buttons using the .button class
<a href="#" class="button">Anchor</a>
Turn inputs into buttons using the same .button class
<input type="submit" class="button" value="Submit">
Center a button with the .display-table utility class
<input type="submit" class="button display-table" value="Submit">
For full-width buttons, stack .button-wide after .button
<div class="grid">
<div class="column md-12">
<a class="button button-wide">.button .button-wide</a>
</div>
<div class="column md-12">
<a class="button button-wide">.button .button-wide</a>
</div>
</div>
Adding .image will make any image mobile responsive
Stacking .image-round will make any image a circle
Stacking .image-rounded will give any image rounded corners
Stacking .display-block will center any image
<img src="http://placehold.it/200x200" class="image image-example">
<img src="http://placehold.it/200x200" class="image image-example">
<img src="http://placehold.it/200x200" class="image image-example">
Form syntax is nearly unchanged. By default form fields have basic styles just to clean up paddings and margins, just surround the necessary columns in a < form >
<form>
<div class="column md-12">
<label>Name</label>
<input type="text" placeholder="name">
</div>
<div class="column md-12">
<label>Password</label>
<input type="password">
</div>
<div class="column md-24">
<label>Email Address</label>
<input type="email" placeholder="contact@lethalin.com">
<label>Message</label>
<textarea rows="3"></textarea>
<input type="submit" class="button" value="Submit">
<input type="submit" class="button" value="Cancel">
</div>
</form>
Tables are also very easy, just wrap your standard table inside a .table class.
<div class="column">
<div class="table">
<table>
<tr>
<th>Rank</th>
<th>Movie Title</th>
<th>Genre</th>
<th>Year</th>
</tr>
<tr>
<th>1</th>
<td>The Fellowship of the Ring</td>
<td>Adventure, Fantasy</td>
<td>2001</td>
</tr>
<tr>
<th>2</th>
<td>Star Wars</td>
<td>Adventure, Sci-fi</td>
<td>1977</td>
</tr>
<tr>
<th>3</th>
<td>Iron Man</td>
<td>Sci-fi, Comic Book</td>
<td>2008</td>
</tr>
</table>
</div>
</div>
Modal overlays require very little mark up and are supported on devices of all different sizes. It's always best practice to place your modals towards the top of your document to avoid any confliction with other elements.
To create modals, use the following mark up:
<div id="examplemodal-modal" class="overlay">
<div class="modal">
<h2>Modal Overlay</h2>
<div class="content">
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.</p>
</div>
</div>
</div>
Every instance of a modal will require the id to be "IDNAME-modal". Javascript checks the DOM for any elements with an id ending in "-modal", if it's found, its considered a modal. To trigger and open a modal, give any anchor, button or element the "button-modal" class and a matching id.
<a id="examplemodal" class="button button-modal">Get Started Today</a>
Basic helper classes, these will be updated as the framework grows.
