Theme Documentation - Content

Find out how to create and organize your content quickly and intuitively in KeepIt theme.

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

2 Front Matter

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

Here is a front matter example:

3 Content Summaries

KeepIt 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 CJKChinese/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 <!--more--> summary divider where you want to split the article.

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

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 <!--more--> summary divider at the start of the article. Keep content that comes before the summary divider empty. Then KeepIt 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:

1. If there is a <!--more--> summary divider present in the article but no content is before the divider, the description will be used as the summary.
2. If there is a <!--more--> summary divider present in the article the text up to the divider will be provided as per the manual summary split method.
3. 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.
4. The text at the start of the article will be provided as per the automatic summary split method.

4 Basic Markdown Syntax

This part is shown in the basic markdown syntax page .

5 Extended Markdown Syntax

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

Emoji Support

This part is shown in the emoji support page .

Mathematical Formula

KeepIt 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. $\KaTeX$ automatically renders formulas based on specific delimiters.

Inline Formula: 

Block Formula:

Inline Formula

The default inline delimiters are:

• $ ... $
• \( ... \) (escaped: \\( ... \\))

For example:

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

Block Formula

The default block delimiters are:

• $$ ... $$
• \[ ... \] (escaped: \\[ ... \\])
• \begin{equation} ... \end{equation} (unnumbered: \begin{equation*} ... \end{equation*})
• \begin{align} ... \end{align} (unnumbered: \begin{align*} ... \end{align*})
• \begin{alignat} ... \end{alignat} (unnumbered: \begin{alignat*} ... \end{alignat*})
• \begin{gather} ... \end{gather} (unnumbered: \begin{gather*} ... \end{gather*})
• \begin{CD} ... \end{CD}

For example:

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

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

\begin{equation*}
  \rho \frac{\mathrm{D} \mathbf{v}}{\mathrm{D} t}=\nabla \cdot \mathbb{P}+\rho \mathbf{f}
\end{equation*}

\begin{equation}
  \mathbf{E}=\sum_{i} \mathbf{E}\_{i}=\mathbf{E}\_{1}+\mathbf{E}\_{2}+\mathbf{E}_{3}+\cdots
\end{equation}

\begin{align}
  a&=b+c \\\\
  d+e&=f
\end{align}

\begin{alignat}{2}
   10&x+&3&y = 2 \\\\
   3&x+&13&y = 4
\end{alignat}

\begin{gather}
   a=b \\\\
   e=b+c
\end{gather}

\begin{CD}
   A @>a\>> B \\\\
@VbVV @AAcA \\\\
   C @= D
\end{CD}

The rendered output looks like this:

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

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

\begin{equation*} \rho \frac{\mathrm{D} \mathbf{v}}{\mathrm{D} t}=\nabla \cdot \mathbb{P}+\rho \mathbf{f} \end{equation*}

\begin{equation} \mathbf{E}=\sum_{i} \mathbf{E}_{i}=\mathbf{E}_{1}+\mathbf{E}_{2}+\mathbf{E}_{3}+\cdots \end{equation}

\begin{align} a&=b+c \\ d+e&=f \end{align}

\begin{alignat}{2} 10&x+&3&y = 2 \\ 3&x+&13&y = 4 \end{alignat}

\begin{gather} a=b \\ e=b+c \end{gather}

\begin{CD} A @>a>> B \\ @VbVV @AAcA \\ C @= D \end{CD}

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 KeepIt theme:

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

The rendered output looks like this:

HugoAn open-source static site generator

Fraction

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

[Light]/[Dark]

[99]/[100]

The rendered output looks like this:

^Light/_Dark

⁹⁰/₁₀₀

Font Awesome

KeepIt 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!  Be back soon.

That is so funny!

Escape character

In some special cases (when writing this theme documentation ), 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 :joy:

Another example is:

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

The rendered output looks like this:

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