<p class="commentary firstcommentary"><a id="SP1" class="paragraph-anchor"></a><b>§1. </b>The whole idea of a CSS file is to provide styling independent from content,
|
|
and since <span class="extract"><span class="extract-syntax">indoc</span></span> generates content, it shouldn't meddle with CSS files at
|
|
all. It does so for two reasons:
|
|
</p>
|
|
|
|
<ul class="items"><li>(a) Because the CSS may refer to background images, by URL, and these URLs
|
|
depend on the website structure, which may vary according to the instructions
|
|
and target chosen. So <span class="extract"><span class="extract-syntax">indoc</span></span> needs to correct such URLs on the fly. What it
|
|
does is to replace the word <span class="extract"><span class="extract-syntax">IMAGES/</span></span> with the correct relative path, and this
|
|
also means that the image name is flagged as one that will be needed by the
|
|
resulting website.
|
|
</li><li>(b) Because the instructions have requested one or more changes, or "tweaks",
|
|
to the CSS to be used on a given volume or volumes. Such instructions are
|
|
kept in the following hashes:
|
|
</li></ul>
