Thin UI v2.1.1
https://github.com/getButterfly/thin-ui

Introduction

Thin UI is an opinionated, lightweight UI framework consisting of a Flex-powered column grid and a list of basic components, such as form fields and buttons. Built using a functional CSS approach, which means you get exactly what you ask for, without any hidden surprises. The resulting file size is far smaller than a traditional CSS framework.

Installation

Components

Flex Grid

Thin UI Flex Grid is a lightweight column grid with all the power of flexbox. Built using a functional CSS approach, which means you get exactly what you ask for without any hidden surprises. The resulting file size is far smaller than a traditional column grid.

The Basic Auto Layout

Each column inside the grid is automatically assigned an equal share of the total. The columns are built to respect the layout over the content.

.thin-ui-col
.thin-ui-col
.thin-ui-col
<div class="thin-ui-grid">
    <div class="thin-ui-col">
        Auto Column
    </div>
    <div class="thin-ui-col">
        Auto Column
    </div>
    <div class="thin-ui-col">
        Auto Column
    </div>
</div>

Percentage Based Columns

Based on the familiar n/12 column system.

.thin-ui-col.thin-ui-col-3
.thin-ui-col.thin-ui-col-9
.thin-ui-col.thin-ui-col-4
.thin-ui-col.thin-ui-col-4
.thin-ui-col.thin-ui-col-4
.thin-ui-col.thin-ui-col-5
.thin-ui-col.thin-ui-col-2
.thin-ui-col.thin-ui-col-2
.thin-ui-col.thin-ui-col-3
<div class='thin-ui-grid'>
  <div class='thin-ui-col thin-ui-col-3'>
    25% (3/12)
  </div>
  <div class='thin-ui-col thin-ui-col-9'>
    75% (9/12)
  </div>
</div>

Flex Grow Columns

Based on flex-grow, this layout style allows for dynamic content distribution. These columns will respect their given ratio and resist dropping onto a second row unlike a percentage based column.

.thin-ui-col.thin-ui-col-grow-2
.thin-ui-col
.thin-ui-col
.thin-ui-col.thin-ui-col-grow-3
.thin-ui-col.thin-ui-col-grow-2
.thin-ui-col
.thin-ui-col.thin-ui-col-grow-3
.col
<div class='thin-ui-grid'>
  <div class='thin-ui-col thin-ui-col-grow-3'>
    Grow 3 Columns
  </div>
  <div class='thin-ui-col'>
    Auto Column
  </div>
</div>

Fixed Columns

Add in the fixed column class and pass the column a defined width or allow content like an image to dictate the desired width. It's recommended to fill the space with dynamic flex columns however you can mix in percent based columns too. Utilizing a fixed column with only percent based columns will make it difficult to reach 100%.

Fixed 168px
Auto Width
.col.col-fixed
.col
.col
<div class='thin-ui-grid'>
  <div class='thin-ui-col thin-ui-col-fixed' style='width:168px;'>
    thin-ui-col thin-ui-col-fixed
  </div>
  <div class='thin-ui-col'>
    thin-ui-col
  </div>
  <div class='thin-ui-col'>
    thin-ui-col
  </div>
</div>

Mixed Columns

This is the real power of flexbox at work in your layouts.

Fixed 168px
Dynamic Width
.thin-ui-col.thin-ui-col-fixed
.col.col-grow-2
.col

.thin-ui-col.thin-ui-col-fixed
.thin-ui-col.thin-ui-col-grow-2

<div class='thin-ui-grid'>
  <div class='thin-ui-col thin-ui-col-fixed' style='width:168px;'>
    Fixed Column
  </div>
  <div class='thin-ui-col thin-ui-col-grow-2'>
    Grow 2 Column
  </div>
  <div class='thin-ui-col'>
    Auto Column
  </div>
  <div class='thin-ui-col thin-ui-col-3'>
    25% (3/12)
  </div>
</div>

Content Alignment

Vertically align the content inside of a column.

.thin-ui-col-top
.thin-ui-col-middle
.thin-ui-col-bottom
<div class='thin-ui-grid'>
  <div class='thin-ui-col thin-ui-col-top' style='height:96px;'>
    Content aligned to top
  </div>
  <div class='thin-ui-col thin-ui-col-middle' style='height:96px;'>
    Content aligned to middle
  </div>
  <div class='thin-ui-col thin-ui-col-bottom' style='height:96px;'>
    Content aligned to bottom
  </div>
</div>

Column Vertical Alignment

Columns alignment relative to each other inside of the .thin-ui-grid container.

.thin-ui-col-align-top
.thin-ui-col-align-middle
.thin-ui-col-align-bottom
Tall column expanding
the height of
the grid container
<div class='thin-ui-grid'>
  <div class='thin-ui-col thin-ui-col-align-top'>
    Top Aligned Column
  </div>
  <div class='thin-ui-col thin-ui-col-align-middle'>
    Middle Aligned Column
  </div>
  <div class='thin-ui-col thin-ui-col-align-bottom'>
    Bottom Aligned Column
  </div>
  <div class='thin-ui-col' style='height:112px;'>
    Tall Column
  </div>
</div>

Grid Horizontal Alignment

Apply modifier classes to the .thin-ui-grid element to change the alignment of columns.

.thin-ui-grid-start .thin-ui-col.thin-ui-col-6
.grid-center .thin-ui-col.thin-ui-col-3
.grid-center .thin-ui-col.thin-ui-col-3
.thin-ui-grid-end .thin-ui-col.thin-ui-col-6
<div class='thin-ui-grid thin-ui-grid-end'>
  <div class='thin-ui-col thin-ui-col-6'>
    Aligned to the end
  </div>
</div>

Column Distribution

Distribute space around or between columns equally.

.thin-ui-grid-around .thin-ui-col.thin-ui-col-3
.thin-ui-grid-around .thin-ui-col.thin-ui-col-3
.thin-ui-grid-around .thin-ui-col.thin-ui-col-3
.thin-ui-grid-between .thin-ui-col.thin-ui-col-3
.thin-ui-grid-between .thin-ui-col.thin-ui-col-3
.thin-ui-grid-between .thin-ui-col.thin-ui-col-3
<div class='thin-ui-grid thin-ui-grid-between'>
  <div class='thin-ui-col thin-ui-col-3'>
    Equal space between columns
  </div>
  <div class='thin-ui-col thin-ui-col-3'>
    Equal space between columns
  </div>
  <div class='thin-ui-col thin-ui-col-3'>
    Equal space between columns
  </div>
</div>

Column Ordering

Change the order of columns by using the modifier classes .thin-ui-col-first to move a column to the first position or .thin-ui-col-last to move it to the last position.

1
2
3
1
2
.thin-ui-col-first

  <div class='thin-ui-col'>
    2nd Column
  </div>
  <div class='thin-ui-col'>
    3rd Column
  </div>
</div>

Grids nest easily with no cascading conflicts. Great for complex layouts.

Modal Dialog

Usage

Import thin-ui.css and thin-ui-modal.js into your HTML.

<link rel="stylesheet" href="thin-ui.css">
<script src="thin-ui-modal.js"></script>

Add a function that will call the modal dialog, to handle the Promise. Based on modalResponse value (true, false or null), execute any code or action you need.

async function openModal() {
    this.myModal = new SimpleModal('Hello there!', 'Do you like this modal popup? It is very light and easy to configure.', 'Sure, 100%', 'Not really, no');
    try {
        const modalResponse = await myModal.question();

    } catch (err) {
        console.log(err);
    }
}
