Since LaTeX2Web components are crated from extended LaTeX command, you can define custom web components with LaTeX macros.
We are going to create a custom style card component that will mimic a Post-It note.
The requirements are the following:
To do so, we use the \newenvironment command to create a postIt environment. This environment will use a single parameter, which will be the note title. The content of the environment will be the content of the note. Remember that the components of the LaTeX2Web card can be styled. Here is the definition of the environment.
\newenvironment{postIt}[1]{
\begin{card}
\begin{header}
\begin{style}
\background{black}
\textcolor{white}
\end{style}
#1
\end{header}
\begin{body}
\begin{style}
\background{lightyellow}
\end{style}
}
{
\end{body}
\end{card}
}And here is a very basic usage.
\begin{postIt}{I am the title}
I am the content.
I am a LaTeX2Web \ref{LaTeX2Web-cards/chunks}[chunk] and I can have a variety of content.
\end{postIt}Here is the result.
I am the title
I am the content.
I am a LaTeX2Web chunk and I can have a variety of content.
