1 Contents Organization

A few suggestions to help you get a good looking site quickly:

Keep post pages in the content/posts directory, for example: content/posts/my-first-post.md
Keep other pages in the content directory, for example: content/about.md
Local resources organization

There are three ways to reference local resources such as images and music:

Using page resources in page bundles. You can reference page resources by the value for Resources.GetMatch or the filepath of the resource relative to the page directory directly.
Store resources in the assets directory, which is /assets by default. The filepath of the resource to reference in the post is relative to the assets directory.
Store resources in the static directory, which is /static by default. The filepath of the resource to reference in the post is relative to the static directory.

The priority of references is also in the above order.

There are many places in the theme where the above local resource references can be used, such as links, images, image shortcode, music shortcode and some params in the front matter.

Images in page resources or assets directory processing will be supported in the future. It's really cool! :(far fa-grin-squint fa-fw): {{< /admonition >}}

2 Front Matter

Hugo allows you to add front matter in yaml, toml or json to your content files.

{{< admonition >}} Not all of the below front matters need to be set in each of your posts. It is necessary only if the front matters and the page part in your site configuration are inconsistent. {{< /admonition >}}

Here is a front matter example:

---
title: "My First Post"
subtitle: ""

resources:
- name: featured-image
  src: featured-image.jpg
- name: featured-image-preview
  src: featured-image-preview.jpg

3 Content Summaries

LoveIt theme uses the summary of the content to display abstract information in the home page. Hugo can generate summaries of your content.

Automatic Summary Splitting

By default, Hugo automatically takes the first 70 words of your content as its summary.

You may customize the summary length by setting summaryLength in the site configuration.

If you are creating content in a [CJK]^(Chinese/Japanese/Korean) language and want to use Hugo’s automatic summary splitting, set hasCJKLanguage to true in your site configuration.

Manual Summary Splitting

Alternatively, you may add the  summary divider where you want to split the article.

Content that comes before the summary divider will be used as that content’s summary.

{{< admonition >}} Be careful to enter  exactly; i.e., all lowercase and with no whitespace. {{< /admonition >}}

Front Matter Summary

You might want your summary to be something other than the text that starts the article. In this case you can provide a separate summary in the summary variable of the article front matter.

Use Description as Summary

You might want your description in the description variable of the article front matter as the summary.

You may add the  summary divider at the start of the article. Keep content that comes before the summary divider empty. Then LoveIt theme will use your description as the summary.

Priority Order of Summary Selection

Because there are multiple ways in which a summary can be specified it is useful to understand the order. It is as follows:

If there is a  summary divider present in the article but no content is before the divider, the description will be used as the summary.
If there is a  summary divider present in the article the text up to the divider will be provided as per the manual summary split method.
If there is a summary variable in the article front matter the value of the variable will be provided as per the front matter summary method.
The text at the start of the article will be provided as per the automatic summary split method.

{{< admonition >}} It is not recommended to include rich text block elements in the summary, which will cause typographic errors. Such as code blocks, pictures, tables, etc. {{< /admonition >}}

4 Basic Markdown Syntax

This part is shown in the basic markdown syntax page.

5 Extended Markdown Syntax

LoveIt theme has some extended syntax elements for you to write articles.

Emoji Support

This part is shown in the emoji support page.

Mathematical Formula

LoveIt theme supports mathematical formulas based on $ \KaTeX $.

Set the property enable = true under [params.math] in your site configuration and the property math: true of the article front matter to enable the automatic rendering of mathematical formulas.

{{< admonition tip >}} Here is a list of \TeX functions supported by $ \KaTeX $. {{< /admonition >}}

Block Formula

The default block delimiters are $$/$$ and \\[/\\]:

$$ c = \pm\sqrt{a^2 + b^2} $$

\\[ f(x)=\int_{-\infty}^{\infty} \hat{f}(\xi) e^{2 \pi i \xi x} d \xi \\]

The rendered output looks like this:

 c = \pm\sqrt{a^2 + b^2}

\[ f(x)=\int_{-\infty}^{\infty} \hat{f}(\xi) e^{2 \pi i \xi x} d \xi \]

Inline Formula

The default inline delimiters are $/$ and \$/\$:

$ c = \pm\sqrt{a^2 + b^2} $ and \\( f(x)=\int_{-\infty}^{\infty} \hat{f}(\xi) e^{2 \pi i \xi x} d \xi \\)

The rendered output looks like this:

c = \pm\sqrt{a^2 + b^2} and $ f(x)=\int_{-\infty}^{\infty} \hat{f}(\xi) e^{2 \pi i \xi x} d \xi $

{{< admonition tip >}} You can add more block and inline delimiters in your site configuration. {{< /admonition >}}

Copy-tex

Copy-tex is an extension for $ \KaTeX $.

By the extension, when selecting and copying \KaTeX rendered elements, copies their \LaTeX source to the clipboard.

Set the property copyTex = true under [params.math] in your site configuration to enable Copy-tex.

Select and copy the formula rendered in the previous section, and you can find that the copied content is the LaTeX source code.

mhchem

mhchem is an extension for $ \KaTeX $.

By the extension, you can write beautiful chemical equations easily in the article.

Set the property mhchem = true under [params.math] in your site configuration to enable mhchem.

$$ \ce{CO2 + C -> 2 CO} $$

$$ \ce{Hg^2+ ->[I-] HgI2 ->[I-] [Hg^{II}I4]^2-} $$

The rendered output looks like this:

 \ce{CO2 + C -> 2 CO}

 \ce{Hg^2+ ->[I-] HgI2 ->[I-] [Hg^{II}I4]^2-}

Ruby Annotation

An extended Markdown syntax for ruby annotation is supported in LoveIt theme:

[Hugo]{?^}(An open-source static site generator)

The rendered output looks like this:

[Hugo]^(An open-source static site generator)

Fraction

An extended Markdown syntax for fraction is supported in LoveIt theme:

[Light]{?/}[Dark]

[99]{?/}[100]

The rendered output looks like this:

[Light]/[Dark]

[90]/[100]

Font Awesome

LoveIt theme uses Font Awesome as the icon library. You can easily use these icons in your articles.

Get the class of icons you wanted from the Font Awesome website.

Gone camping! {?:}(fas fa-campground fa-fw): Be back soon.

That is so funny! {?:}(far fa-grin-tears):

The rendered output looks like this:

Gone camping! :(fas fa-campground fa-fw): Be back soon.

That is so funny! :(far fa-grin-tears):

Escape character

In some special cases (when writing this theme documentation :(far fa-grin-squint-tears):), your content will conflict with basic or extended Markdown syntax, and it is inevitable.

The escape character syntax can help you build the content you wanted:

{{??}X} -> X

For example, two : will enable emoji syntax, which is not the behavior you want. The escape character syntax is like this:

{{??}:}joy:

The rendered output looks like this:

{?:}joy{?:} instead of 😂

{{< admonition tip >}} This is related to an issue for Hugo, which has not been resolved. {{< /admonition >}}

Another example is:

[link{{??}]}(#escape-character)

The rendered output looks like this:

[link{?]}(#escape-character) instead of link.
