cd ./< your blog project >/themes/
2-3. Clone coast theme to theme directory and remove .git directory of coast theme repository
git clone https://github.com/Myxogastria0808/coast.git
rm -rf coast/.git
2-4. Change directory to the root of your blog project
cd ..
2-5. Replace settings to config.toml of your blog project
The following is the content of the replacement config.
Please change base_url to your blog's URL when deploying your blog.
During development, I recommend leaving base_url as is.
theme = "coast"
# The URL the site will be built for
base_url = "/"
# The site title and description; used in feeds by default.
title = "coast"
description = "A simple theme for Zola that evokes the feel the sea breeze."
# Whether to automatically compile all Sass files in the sass directory
compile_sass = true
# When set to "true", the generated HTML files are minified.
minify_html = true
# Whether to build a search index to be used later on by a JavaScript library
build_search_index = true
# RSS/Atom feeds
generate_feeds = true
# The filenames to use for the feeds. Used as the template filenames, too.
# Defaults to ["atom.xml"], which has a built-in template that renders an Atom 1.0 feed.
# There is also a built-in template "rss.xml" that renders an RSS 2.0 feed.
feed_filenames = ["rss.xml"]
# The taxonomies to be rendered for the site and their configuration of the default languages
# Example:
# taxonomies = [
# {name = "tags", feed = true}, # each tag will have its own feed
# {name = "tags"}, # you can have taxonomies with the same name in multiple languages
# {name = "categories", paginate_by = 5}, # 5 items per page for a term
# {name = "authors"}, # Basic definition: no feed or pagination
# ]
#
taxonomies = [
{name = "tags", feed = true},
]
[markdown]
# Whether to do syntax highlighting
# Theme can be customized by setting the `highlight_theme` variable to a theme supported by Zola
highlight_code = true
# When set to "true", emoji aliases translated to their corresponding
# Unicode emoji equivalent in the rendered Markdown files. (e.g.: :smile: => 😄)
render_emoji = true
# Whether external links are to be opened in a new tab
# If this is true, a `rel="noopener"` will always automatically be added for security reasons
external_links_target_blank = true
# Whether to set rel="noreferrer" for all external links
external_links_no_referrer = true
# Whether smart punctuation is enabled (changing quotes, dashes, dots in their typographic form)
# For example, `...` into `…`, `"quote"` into `“curly”` etc
smart_punctuation = true
[search]
# Whether to include the title of the page/section in the index
include_title = true
# Whether to include the description of the page/section in the index
include_description = true
# Whether to include the RFC3339 datetime of the page in the search index
include_date = true
# Whether to include the path of the page/section in the index (the permalink is always included)
include_path = true
# Whether to include the rendered content of the page/section in the index
include_content = true
[slugify]
# Various slugification strategies, see below for details
# Defaults to everything being a slug
paths = "off"
taxonomies = "off"
# Whether to remove date prefixes for page path slugs.
# For example, content/posts/2016-10-08_a-post-with-dates.md => posts/a-post-with-dates
# When true, content/posts/2016-10-08_a-post-with-dates.md => posts/2016-10-08-a-post-with-dates
paths_keep_dates = true
2-6. Add extra settings to config.toml of your blog project
This theme provides the following additional settings.
All settings have default values, so you only need to add the settings you want to change.
config.toml[extra.coast]
# default value: 'en'
lang = "en"
# default value: 'blog'
keyword = "blog"
# default value: 'https://raw.githubusercontent.com/Myxogastria0808/coast/heads/main/static/favicon.svg'
# A shortcut icon has to be a SVG image.
icon = "https://raw.githubusercontent.com/Myxogastria0808/coast/heads/main/static/favicon.svg"
# default value: ''
twitter_site = ""
# default value: '@yuki_osada0808'
twitter_creator = "@yuki_osada0808"
# default value: 'https://raw.githubusercontent.com/Myxogastria0808/coast/heads/main/static/first-view.jpg'
meta_image = "https://raw.githubusercontent.com/Myxogastria0808/coast/heads/main/static/first-view.jpg"
# default value: 'coast theme'
meta_image_alt = "coast theme"
# default value: '3024'
meta_image_width = "3024"
# default value: '3024'
meta_image_height = "3024"
# default value: 'https://raw.githubusercontent.com/Myxogastria0808/coast/heads/main/static/first-view.jpg'
first_view_image = "https://raw.githubusercontent.com/Myxogastria0808/coast/heads/main/static/first-view.jpg"
# default value: 'Hello, World!'
about_title = "Hello, World!"
# default value is below
about_description = """
Hello, my name is Myxogastria0808.<br/>
I created a Zola theme named "coast".
This template can be used mermaid and katex.<br/>
Have a nice day!
"""
config.toml)[extra.coast]
keyword = "blog coast sea"
about = """
Hello, my name is Myxogastria0808.<br/>
This blog is made by Zola. This is a sample blog of coast theme.
"""
2-7. Replace settings to content/_index.md of your blog project
The following is the content of _index.md, which will be newly added in the content directory.
_index.md+++
sort_by = "date"
template = "index.html"
page_template = "blog-template.html"
in_search_index = true
+++
zola build
zola serve
The following sample have been set up.
[!NOTE] This repository includes the coast theme repository as a submodule.
https://github.com/Myxogastria0808/coast-sample.git
https://zola-coast-theme-sample.netlify.app/
You can see the post example below.
+++
title = "coast"
date = 2025-08-19
authors = ["Myxogastria0808"]
[taxonomies]
tags = ["coast"]
+++
I don’t live by the sea, but whenever I travel and find myself on a shoreline, I feel something special—the rhythm of the waves, the endless horizon, and the quiet moments that stay with me long after I’ve left.
## Greeting
Hello, lovers of the sea! 🌊
My name is Myxogastria0808, and I like the sea too!
## coast logo
I create a logo for my blog theme named "coast".
{{ image(path="/content/coast/coast.png") }}
Please refer to the following for an actual example.
https://github.com/Myxogastria0808/coast/blob/main/content/sample/index.md
https://zola-coast-theme.netlify.app/sample/
https://www.getzola.org/documentation/content/syntax-highlighting/
```rs
fn main() {
println!("Hello, world!");
}
```
{{ image(path="/image/path") }}
You can add width=int, height=int, and caption=String as options for image shortcode.
You can see the image shortcode examples below.
