The code syntax highlighting feature is only enabled on certain sites. In order for code to be highlighted and for any of the hints listed in the above question to work, the Markdown extension has to be enabled on the site where one's posting code.
The syntax highlighting feature is enabled on the following sites:
Note that the above list consists of per-site metas as well, as there are some sites where it's enabled on the main site but not on the corresponding per-site meta. The above list was last updated 2023-08-13; if it becomes outdated, please copy the Markdown generated by the below code snippet and replace the above list with that, and then update the date here.
The following code snippet fetches the list of sites with syntax highlighting enabled.
$.get('https://api.stackexchange.com/2.2/sites?pagesize=500&filter=!*L6SiaRiUSk*Z2zr', function(data) {
var i,
$result = $('#result'),
$md = $('#md'),
sites = [],
specials = {
biology : { mhchem: true},
chemistry: {mhchem: true },
earthscience: {mhchem: true },
electricalengineering: {delim: true},
codereview: {delim: true}
},
sec,

for(i=0; i < data.items.length; i++) {
if (data.items[i].markdown_extensions &&
data.items[i].markdown_extensions.indexOf('Prettify')>-1) //Even after the changeover to Highlight.js, the Markdown extension is still called "Prettify"
{
sites.push(data.items[i]);
}
}
sites.sort(function(l,r) { return l.name<r.name?-1:1; });
for(i = 0; i < sites.length; i = i + 1) {
$result.append(
$('<li></li>').html(sites[i].name)
);
$md.append(
$('<pre></pre>').html('1. [' + sites[i].name+'](' + sites[i].site_url.substr(sites[i].site_url.indexOf(':') + 1) + ')')
);

Normally, syntax highlighting will be enabled by staff when newly creating the site, based on the scope of the site's Area 51 proposal and how strongly it is focused on programming. If it's not enabled on a given site, you can post a request on the per-site meta tagged feature-request syntax-highlighting to have it enabled in the following cases:
The site topic is primarily focused on programming, but syntax highlighting wasn't enabled due to oversight.
The site topic isn't primarily focused on programming, but the site could substantially benefit from one or more particular flavors of syntax highlighting. In this case, link to some (10 or so) posts where highlighting would be helpful in your request.
Syntax highlighting is enabled on a main site but not on its per-site meta, and you feel it's useful to have enabled on the meta site. In this case, ensure your request has the meta tag and clearly explains that it's asking about the meta site.
If there is community consensus in support of such a request, a site moderator can add the status-review tag to the meta post to escalate it for staff attention. SE staff will then evaluate the request and let you know the result.
nginx is not working, while in Stack Overflow it does. There's a similar question on Meta about that here
