    I'm evaluating elinks as a candidate component for a toolchain in
    which I have to translate html to plain text, obeying some
    housestyle rules. [Namely, in the production of ebooks for Project
    Gutenberg]. For instance, I have to render all
    &lt;strong&gt;tags&lt;/strong&gt; into *tags*, to add four blank
    lines before any &lt;h2&gt; and two after, white-space indentations
    in some places, changing &lt;span dir=3D"rtl"&gt;&lt;/span&gt; with
    unicode directionals, and so on.<br>
    <br>
    Elinks provides me a with much better solution than other
    html-to-text tools (I've assessed w3m, links2, lynx, html2text.py,
    netrik), because it honors to some extent the css. However, I have
    some questions about what is supported and what not, and to which
    extent renderings could be customized, if possible without hacking
    the source code.<br>
    <br>
    Some of the transformations I need to do toward the required text
    rendering, could in fact be done by preliminary regexp substitutions
    in the source html, and/or subsequent substitutions in the result.
    However, the toolchain would be a lot more streamlined if I could
    add some lines to my css, and let elinks work. For instance, <br>
    <br>
    =C2=A0=C2=A0=C2=A0 strong:before { content: '*'; }<br>
    =C2=A0=C2=A0=C2=A0 strong:after { content: '*'; }<br>
    <br>
    would take care of what exemplified above.<br>
    <br>
    I'm typically using elinks 0.12pre5 with<br>
    <br>
    =C2=A0=C2=A0=C2=A0 elinks -dump-width 80 -no-numbering -no-references=
 -dump 1
    $1.html &gt; $1.txt<br>
    <br>
    The first batch of questions which comes up is:<br>
    <br>
    -are :strong and :after css selectors honored? [not as I can see;
    could they?]<br>
    <br>
    -are margin, padding and text-indent properties honored in some way,
    by adding an appropriate number of blanks? [ditto]<br>
    <br>
    -why -dump produces a text with 4 blanks at the beginning of each
    line, and can this be changed?<br>
    <br>
    -how can I change the number of blank lines before and after
    &lt;h1&gt;,&lt;h2&gt;,...,?<br>
    <br>
    -when elinks dumps, is it using a particular @media selector?<br>
    <br>
    -Is the unstable snapshot more advanced in any respect relevant to
    me?<br>
    <br>
    Thanks in advance for any hint and for providing this nice piece of
    software.<br>
    <br>
