# Theming Hai!

{% hint style="info" %}

## Things to keep in mind

* Backgrounds are added to `html`. Do not block html from being seen entirely. `body` can be use to apply a filter or effect over the image, and `background-filters` can be added to `html`.
* Fonts should not be defined in the theme: fonts are selected by the user, and will be overridden by their selection.
  {% endhint %}

## Special selectors

### `.animationOff { }`

Used to specifically define a class without animation. Hai! will attempt to disable most animations when the Visual Effects setting is switched off.

A good example of this might be the user experience when changing the Visual Effects setting in Hai!. When disabled, users can expect to see a less animated experience with fewer flashy visuals. This means that certain classes or design elements may be less flashy or less pronounced than usual. In other words, users can expect a toned-down UI when the Visual Effects setting is turned off.

### `.nc, .lc, .hc`

Hai! has 4 contrast settings: Default/Theme (no selector), High Contrast (.hc), Normal Contrast (.nc) and Low Contrast (.lc). 

By default, Low Contrast makes all elements and text softer. Normal removes any modifications to text including text-shadows. High Contrast adds outlines to the text.

Default/Theme has no selector, as is the default for what fits your theme best.

### `[scroller=`*`left,top`*`] { }`

The navigation bar can be made to overflow and scroll. Some buttons will not be visible until scrolled to.. When the user taps on one of the navigation buttons, the viewport for the navigation area can be made to scroll to the button that was pressed. 

This selector accepts no rules, and acts like a flag to enable this behavior. The options for it are `left` or `top`

Hai! looks for this option as the second selector in the theme file. If it is not present there, the effect will not be enabled. The included *WP7* theme uses this for it's Metro-style navigation bar.

### `.isVisible {}`

Post content has the class `.isVisible` added to it when it starts to become visible in the timeline. This can be used for arranging or animating incoming posts. The platforms this works on are limited to mostly the iPhone at the moment.

### `.action_boost, .action_fav, .action_unboost, .action_unfav`

When a button on a post is pressed, `.action` classes are added to the `body`. The included *Cute* theme uses these to create full window animations using `.action_{action}::after`

### `.notification.favourite, notification.reply, .notification.share`

Styles applied to notifications to indicate type

### `.shared, .favorited {}`

Classes added to the the boost and favourite buttons to indicate their state 

### `.sk-grid, .sk-grid-cube {}`

These make up the waiting animations while Hai! is in a loading state. The animation appears when `.showLoad` is attached to `.sk-grid`.

### `.deleteVisualItem {}`

This class is attached on any element that is being deleted. 

## `.spoiler_text, .spoiler_text.ns`

.spoiler\_text.ns is used when the post is hidden (usually behind .spoiler\_text). Styles for when the post is visible are .spoiler\_text.

## .`isDesktop`

Yes, yes, user agent sniffing is bad. However, using media queries, if the device being used is deemed to be a desktop (or iPad at the moment), the class `.isDesktop` will be added to the body.

## Included Animations

[***Animate.css***](https://animate.style) animations are built into Hai! In addition, these animations can also be used: 

* `crumple`
* `attentionShake`
