How to make a text bigger in the body of a question

Question

I know if I want to make italic some text in the body of my question I should put it between two *'s. Also if I want to make bold some text, I should put it between **'s.

How I can make some text bigger? I tried the html code <font size="7">some text</font> without success.

Answer 1

You can't, since only a subset of HTML tags are supported in the network's visual editor.

The following is taken directly from the Help Center on Formatting:

When posting on TeX - LaTeX Stack Exchange, you can use the visual editor (for questions and answers, but not comments), Markdown, and some HTML. If you're new to Markdown, you may want to visit the official Markdown syntax reference page.

"Some HTML" here refers to the following tags:

<a>              - hyperlink.
<b>              - bold, use as last resort <h1>-<h3>, <em>, and <strong> are 
                   preferred.
<blockquote>     - specifies a section that is quoted from another source.
<code>           - defines a piece of computer code.
<del>            - delete, used to indicate modifications.
<dd>             - describes the item in a <dl> description list.
<dl>             - description list.
<dt>             - title of an item in a <dl> description list.
<em>             - emphasized.
<h1>, <h2>, <h3> - headings.
<i>              - italic.
<img>            - specifies an image tag.
<kbd>            - represents user input (usually keyboard input).
<li>             - list item in an ordered list <ol> or an unordered list <ul>.
<ol>             - ordered list.
<p>              - paragraph.
<pre>            - pre-element displayed in a fixed width font and and 
                   unchanged line breaks.
<s>              - strikethrough.
<sup>            - superscript text appears 1/2 character above the baseline 
                   used for footnotes and other formatting.
<sub>            - subscript appears 1/2 character below the baseline.
<strong>         - defines important text.
<strike>         - strikethrough is deprecated, use <del> instead.
<ul>             - unordered list.
<br>             - line break.
<hr>             - defines a thematic change in the content, usually via a 
                   horizontal line.

Important Notes

• HTML tags unlisted above are stripped from the output. They may render in the client preview, but they will always be removed on the server.

• You must enter the tags exactly as shown. Any deviation from this list—adding extra spaces, using single quote or no quotes, etc.—means the tag will be stripped.

• We do not (and will not) allow <table> tags. Sorry. This is intentional and by design. If you need a quick and dirty "table", use <pre> and ASCII layout.

Answer 2

Seeing your last comment: You could easily include that in your MWE, compile it and add a picture of it as a whole. The MWE could look like this. I don't think it's much reasonable to try to resemble LaTeX's output by HTML this way.

\documentclass{article}
\begin{document}
This is a text~\cite{one,two,three,four}.

\begin{thebibliography}{MM}
\bibitem{one} Item One.
\bibitem[\mbox{\itshape 2}]{two} Item Two.
\bibitem[\mbox{\bfseries 3}]{three} Item Three.
\bibitem[\mbox{\Large 4}]{four} Item Four.
\end{thebibliography}
\end{document}

Answer 3

You could of course say:

It renders as

[1]

rather than [1]
