LaTeX2Web, a web authoring and publishing system

If you see this, something is wrong

Collapse and expand sections

To get acquainted with the document, the best thing to do is to select the "Collapse all sections" item from the "View" menu. This will leave visible only the titles of the top-level sections.

Clicking on a section title toggles the visibility of the section content. If you have collapsed all of the sections, this will let you discover the document progressively, from the top-level sections to the lower-level ones.

Cross-references and related material

Generally speaking, anything that is blue is clickable.

Clicking on a reference link (like an equation number, for instance) will display the reference as close as possible, without breaking the layout. Clicking on the displayed content or on the reference link hides the content. This is recursive: if the content includes a reference, clicking on it will have the same effect. These "links" are not necessarily numbers, as it is possible in LaTeX2Web to use full text for a reference.

Clicking on a bibliographical reference (i.e., a number within brackets) will display the reference.

Speech bubbles indicate a footnote. Click on the bubble to reveal the footnote (there is no page in a web document, so footnotes are placed inside the text flow). Acronyms work the same way as footnotes, except that you have the acronym instead of the speech bubble.

Discussions

By default, discussions are open in a document. Click on the discussion button below to reveal the discussion thread. However, you must be registered to participate in the discussion.

If a thread has been initialized, you can reply to it. Any modification to any comment, or a reply to it, in the discussion is signified by email to the owner of the document and to the author of the comment.

Publications

The blue button below that says "table of contents" is your tool to navigate in a publication.

The left arrow brings you to the previous document in the publication, and the right one brings you to the next. Both cycle over the publication list.

The middle button that says "table of contents" reveals the publication table of contents. This table is hierarchical structured. It has sections, and sections can be collapsed or expanded. If you are a registered user, you can save the layout of the table of contents.

Paragraphs and sections

François Chaplais

1 Introduction

Running text is structured in paragraphs and sections.

2 Paragraphs

Paragraphs are chunks of running text which are separated by one (or more) blank lines.

While paragraphs, per se, do not exist in plain LaTeX, they are full class citizens in HTML. In HTML, a paragraph begins with the opening tag <p> and ends with the closing tag </p>.

3 Sections

Sectioning commands define the hierarchical organization of the document. Here is a top-down list of sectioning commands.

  1. \part
  2. \chapter
  3. \section
  4. \subsection
  5. \subsubsection
  6. \paragraph (which is not the same as running text paragraphs)
  7. \subparagraph

This text belongs to a section. Inside this section, we can embed a

  • subsection
  • subsubsection
  • paragraph
  • subparagraph

Here is an illustration.

3.1 I am the title of a subsection

This is the beginning of the subsection content. This content includes the following subsubsection.

3.1.1 This the title of a subsubsection

Let us put some lorem text in the next running text paragraph.

Lorem ipsum excepteur tempor est, nulla in anim magna magna, eu in anim sunt. Ut dolor veniam dolore irure commodo in consectetur minim, sit, et culpa ad. Anim laborum esse magna deserunt cillum adipiscing magna ullamco amet dolor, incididunt velit.

After that, we include a sectioning paragraph.

3.1.1.1 I am a sectioning paragraph

This sectioning paragraph is part of a subsubsection and includes the following subparagraph.

3.1.1.1.1 This is the bottom of the hierarchy

You can visualize the document hierarchy by clicking on section titles. This will hide/reveal the section’s content, including the sections inside.

3.2 Conclusion

Summary 1

Sectioning command structure the hierarchy of the document. Any other LaTeX2Web content belongs somewhere in this hierarchy. The sectioning commands are

  1. \part
  2. \chapter
  3. \section
  4. \subsection
  5. \subsubsection
  6. \paragraph (which is not the same as running text paragraphs)
  7. \subparagraph

4 Terminal types

Other LaTeX2Web objects may have a hierarchical structure. Some objects, by contrast, cannot include any LaTeX2Web object. These object types are called terminal types. Here is a short list.

  • paragraph
  • simple list (like this one), and checklist (like a to-do list)
  • media: image, video, audio
  • equation
  • figure (which is an image with a caption)
  • chart
  • table and CSV table

Tables are NOT meant for layout. The cell content must be running text, and nothing else.
