## Installation

First of all, You need to add config files.
Follow the [Configuration](#configuration) step.

Then, You can download and unpack the theme manually from Github but it's easier to use git to clone the repo.

From the root of your site:

```bash
$ git clone https://github.com/zzossig/hugo-theme-zzo.git themes/zzo
```

If you use git to version control your site, highly recommended, it's best to add the zzo theme as a submodule.

From the root of your site:

```bash
git submodule add https://github.com/zzossig/hugo-theme-zzo.git themes/zzo
```

## Updating

From the root of your site:

```bash
git submodule update --remote --merge
```

## Run example site

From the root of themes/zzo/exampleSite:

```bash
hugo server --themesDir ../..
```

## Layout

### CSS grid for layout

Modern CSS grid is the easiest and cleanest way to layout your pages.

The CSS grid layout are in `assets/sass/layout/_grid.scss`. A lot can be done by just reordering "grid-template-rows". 

### grid structure

|  left 	|  right 	|
|---	|---	|
|  1	|  2	|
|  3 	|  4	|
|  5 	|  6	|
|  7 	|  8	|

* left, right column width ratio => 5 : 2
* 1 => .navbar-main
* 2 => .navbar-side
* 1 + 2 => .navbar
* 3 => .header-main
* 4 => .header-side
* 3 + 4 => .header
* 5 => .main-main
* 6 => .main-side
* 5 + 6 => .main
* 7 => .footer-main
* 8 => .footer-side
* 7 + 8 => .footer

### grid structure example applied in home page

```html
<div class="navbar"></div>
<div class="header"></div>
<div>
  <div class="main-main"></div>
  <div class="main-side"></div>
</div>
<div class="footer></div>
```

## Gallery

There are two ways to make gallery. You can specify **mode** at frontmatter.

```bash
content/gallery/mygallery/index.md

---
title: "{{ replace .Name "-" " " | title }}"
date: {{ .Date }}
description: 
type: gallery
mode: one-by-one # at-once or one-by-one
tags:
-
series:
-
categories:
-
images: # when mode is one-by-one, images front matter works
  - image: image1.jpg
    caption: caption1
  - image: image2.jpg
    caption: caption2
    ...
---

```

If you set the mode to one-by-one, list.html page will use images frontmatter above. If you set the mode to at-once, list.html page will not use images frontmatter and just read all files under the static/gallery/mygallery folder.

1. Make a gallery folder under the content folder

```bash
root
├── content
│   ├── gallery
```

2. Make a sub folder under the gallery folder

```bash
root
├── content
│   ├── gallery
│   │   ├── mygallery
```

3. Make a index.md file under the sub folder using this command

```bash
hugo new gallery/mygallery/index.md
```

4. Put your images in static folder

```bash
root
├── static
│   ├── gallery
│   │   ├── mygallery
│   │   │   ├── ...your images here
```

## Multi Language

The default language of this theme is English. If you want to use another language, follow these steps

1. Make a menu file.

```bash 
root
├── config
│   ├── _default
│   │   ├── ...
│   │   ├── menus.ko.toml
```

```bash
config/_default/menus.ko.toml

[[main]]
  identifier = "about"
  name = "about"
  url = "/about/"
  weight = 1

[[main]]
    identifier = "archive"
    name = "archive"
    url = "/archive/"
    weight = 2
...
```

2. Make a content file. Add your language code before the md extension.

```bash
hugo new about/index.ko.md
hugo new posts/markdown-syntax.ko.md
...
```

3. Make an i18n file.

```bash
i18n/ko.toml

[search-placeholder]
other = "검색..."

[summary-dateformat]
other = "2006년 01월 02일"

[taxo-tags]
other = "태그"

...
```

## Customizing

It's better idea not to modify zzo theme's folder if you wanna future support and upgrade. (You can modify if it doesn't matter) If you want more customizing options, open an issue.

### custom css

1. Add this line of code to your params.toml file

```bash
config/_default/params.toml

...
custom_css = ["css/custom.css", "scss/custom.scss", ...]
...
```

2. Add your file to assets folder. Filename must match with config params you set above.

```bash
assets/scss/custom.scss
assets/css/custom.css
```

3. If you want to modify zzo theme's default color, you should override the theme style. For example, if you want to change the body background-color, because I set the background-color in #body selector, not in body tag selector, you should override body background-color there. body tag selector won't work. And make sure to set !important.

```css
assets/scss/custom.scss or assets/css/custom.css

...
#body {
  background-color: red !important;
}
...
```

### custom js

1. Add this line of code to your params.toml file

```bash
config/_default/params.toml

...
custom_js = ["js/custom.js", ...]
...
```

2. Add your file to assets folder. Filename must match with config params you set above.

```bash
assets/js/custom.js
```

### custom skin(sub theme)

1. Make a skin.toml file in data folder. (data/skin.toml)

2. Copy the contents of themes/zzo/data/skin.toml file and paste it into the skin.toml file you created above.

3. Change the color you want.

4. Edit config/_default/params.toml file. The option name must be custom.

```bash
...
themeOptions = ["custom", "dark", ...]
...
```

5. Once you change the skin.toml file, restart hugo.

### custom font

1. Make a font.toml file in data folder. (data/font.toml)

2. Copy the contents of themes/zzo/data/font.toml file and paste it into the font.toml file you created above.

3. Change the font you want. Make sure that you have imported that font.

4. Once you change the font.toml file, restart hugo.

gallery_contents = "'Merriweather', serif"
list_title = "'Montserrat', sans-serif"
list_desc = "'Merriweather', serif"
single_title = "'Montserrat', sans-serif"
single_contents = "'Merriweather', serif"

```

### custom header

You may want to change home page header. There are 4 options which is slider, image, text, empty.

* Empty

  1. Set params at config/_default/params.toml(homeHeaderType=""). Empty string or just delete it.

This project use swiper library for slider header component.

  3. If you want add some contents, make a file at layouts/partials/header/header-img-content.html and edit as you want.

* Text

  1. Make a file at layouts/partials/header/header-text.html

  2. Edit the file as you want.


### custom grid

1. Make a grid.toml file in data folder. (data/grid.toml)

2. Copy the contents of themes/zzo/data/grid.toml file and paste it into the grid.toml file you created above.

3. Change the grid you want.

4. Once you change the grid.toml file, restart hugo.
