The problem
My post containing some code blocks renders them like "box in a box".
This is the post: https://telatin.github.io/N50-with-conda/ and here what I see from Firefox: http://prntscr.com/oujb6u
The code
This is the source code: https://raw.githubusercontent.com/telatin/telatin.github.io/master/_posts/2019-08-19-N50-with-conda.md
I'm new in using Jekyll, and I tried both triple backticks (as I usually do in GitHub, and the four-spaces at the begin of the line (current implementation). Both renders the same.
Question
I don't understand if the problem is in the code I write or in the template I'm using. What should I do to have a nicer output (single framed)?
If you inspect the generated HTML, you'll see that there are nested blocks with the same class .highlight:
<div class="highlighter-rouge">
<div class="highlight">
<pre class="highlight">
<code>CHECK=$(n50 contigs.fasta)</code>
</pre>
</div>
</div>
What you can do is alter your CSS to be more specific:
i.e. instead of .highlight, use div.highlight for base code-block styles and use
div.highlight > pre.highlight to style the pre block elements if required.

Prettier does a very nice job on HTML generally, but indents pre>code blocks.
I always want pre>code blocks unindented.
Seems like I should be able to configure this in .prettierignore, but can’t find a way that works.
blocks like:
<pre class="line-numbers"><code class="language-json">"operations": [
"video-cloud/video/all",
"video-cloud/playlist/all",
"video-cloud/sharing-relationships/all",
"video-cloud/notifications/all"
]</code></pre>
Get indented like this:
<pre class="line-numbers"><code class="language-json">"operations": [
"video-cloud/video/all",
"video-cloud/playlist/all",
"video-cloud/sharing-relationships/all",
"video-cloud/notifications/all"
]</code></pre>
I want the block left untouched.
Quoting from a deleted answer:
I personally don't use the extension but it seems like prettier has build in configuration for it: https://prettier.io/docs/en/ignore.html
IIUIC, the solution is
<!-- prettier-ignore-start -->
block to keep
<!-- prettier-ignore-end -->
Voting to undelete the answer by "cas v.l." as it led me to the solution in seconds.
You can ignore certain files, but you can't ignore parts of the code.
For future reference. In my case, I'm working on a react project. Adding "{` ..your code.. `}" after pre tag, prettier ignores the block. For example:
<pre>
{`
<div className="row">
<div className="col">
...
</div>
</div>
`}
</pre>
I have a table class that I use to vertically centralise text in a span or div. I am using Handlebars in Node to render several templates server side, I have used this method on several partials in my web project, with no problems.
However in one particular partial / area of markup, either the browser or Handlebars is ignoring or removing the table, tr and td tags, showing only the text that is inside the tags.
In the past when this has happened it was because my tags were incorrect. However I have cross checked this code with my other markup where the table tags do show (in other partials), so I can't see where the problem is, and I can't find any suitable online topic about this (it is probably something really obvious that will make me look like a dummy).
I have tried in Chrome and Edge. I have also tried saving the markup snippet in a .html file (as opposed to a .hbs file) and opening that in the browser, and by doing this it does show the table tags. The consequence of this error is that I am unable to vertically align the text in the span. I am not sure if the markup is invalid according to the browser or Handlebars, but I am not using any {{Handlebars}} tags here so it shouldn't warrant the table tags to be invalid.
Markup:
<div class="lp-menuselector" title="View summary of Individual Learning Plan and evidence pack">
<div class="lp-menuselector-iconholder">
<img src="icons/icon_lp-overview.svg"/>
</div>
<span class="lp-menuselector-textholder">
<table class="tablecellleftalign">
<tr>
<td>
ILP Overview
</td>
</tr>
</table>
</span>
</div>
Output markup shown in Chrome Developer Tools / Elements:
<span class="lp-menuselector-textholder">
ILP Overview
</span>

After I restarted my computer and restarted the Node application, this error no longer occurs. Glitches in the matrix.
I'm trying to create a Jekyll project on Github, styled with Material Design Components. MDC states that Elements are not natively styled, which means that most (if not all) elements will need to be styled with classes. What this means now is that
<div class="mdc-typography">
<div class="mdc-layout-grid max-width">
<div class="mdc-layout-grid__inner">
<div class="mdc-layout-grid__cell mdc-layout-grid__cell--span-8">
```js
// some js
```
</div>
</div>
</div>
</div>
doesn't actually render the code as expected. Rather it renders as plain text. I guess I'm a little new to this. But what is the proper way to nest fenced code blocks within div tags with classes?
The rule for markdown is that it must be indented at least 4 spaces. I am aware of this.
If you are writing this on your jekyll project use
{% highlight javascript %}
{% endhighlight %}

Here is another stack question similar to yours: link
Alternatively, you can style it like it's code.
What I am trying to do:
I am attempting to create a web page with Angular2 which shows HTML on the screen in much the same way many websites do such as stackoverflow, css-tricks, and and w3schools (to name a few). I would like to be able to copy the code and paste it somewhere else after its shown on screen.
What I know:
I have come to realize that it will probably be necessary to convert all of my opening tags ( i.e., < ) to < and to convert all of my closing tags ( i.e., > ) to >, however I am still not sure what the best way to interpolate some variables into the template.
For example, I have this in my template file:
<div>{{myTitle}}</div>
<div><p>{{mySubTitle}}</p></div>
<div>
<ul>
<li>{{item1}}</li>
<li>{{item2}}</li>
<li>{{item3}}</li>
</ul>
</div>
What I want to see (and be able to copy) in the browser:
<div>This is my title</div>
<div><p>This is my subtitle</p></div>
<div>
<ul>
<li>Apple</li>
<li>Orange</li>
<li>Durian</li>
</ul>
</div>
Stack overflow makes this really easy and nice to accomplish by letting you highlight the code you want to display on screen and clicking the {} button in the editor. However, when I try using the <pre> and <code> tags in my Angular2 app, I do not get the same result, I cannot see the actual HTML elements like <div> and <li>.
Instead what I see is:
{{myTitle}}
{{mySubTitle}}
{{item1}}
{{item2}}
{{item3}}
I have used handlebarsjs in the past and am familiar with that library but I was under the impression that using Angular2 would eliminate the need for handlebarsjs. Does anyone know how to accomplish what I am trying to do in Angular2 without handlebarsjs?
For < and > you'll probably need to use < and >.
For the braces in template expressions you may want to use ngNonBindable directive.
<div ngNonBindable> {{myTitle}} </div>
Use <pre> or <code> for HTML to become rendered verbatim.
<pre ngNonBindable>
<div>{{'{{'}}myTitle{{'}}'}}</div>
<div><p>{{'{{'}}mySubTitle{{'{{'}}</p></div>
<div>
<ul>
<li>{{'{{'}}item1{{'{{'}}</li>
<li>{{'{{'}}item2{{'{{'}}</li>
<li>{{'{{'}}item3{{'{{'}}</li>
</ul>
</div>
</pre>
You need to escape { and } (for example like shown above)
I am trying to figure out a way to display an archive of email newsletters on my client's site. The issue is that the newsletters are full of a zillion inline styles, which is great for seeing them in Outlook or wherever, but they're not looking too hot in an otherwise-nicely styled site.
My goal is for my client to be able to copy the entire source code of a generated newsletter (which her list management company* gives her access to) and paste it into the CMS (drupal, if it makes a difference).
*Constant Contact? Mail Chimp? I forget. One of those.
Then I'd like to display it on her site, inside the basic structure (header, nav, etc) of the rest of the site. If this was 1997, I'd say "iframes!" and be done with it, but A) that seems like a lame solution, and B) the code doesn't actually exist on a page by itself, which I think is required for iframes.
Is there some kind of tag I can put around this block of HTML to isolate it from the rest of the site's styles? Or is there another way to go about this entirely?
Thanks!
IFrames are the only way to go that I've ever been able to find. The only alternative to this would be to override every style in the parent page's CSS for the newsletter display area.
As you noted, using an iframe will probably require you to host the newsletters in an independent file. The only alternative to this that I'm aware of is that you can use JavaScript to dynamically create and/or populate the iframe.
If you go with this method, you could have the newsletter present in a div with a specific class, and then use JavaScript to move the div into an iframe. The big downside being that this wouldn't happen for users without JavaScript enabled.
9 years later and there still isn't a better solution.
If you don't have an external source (you can't add html into a frame manually) you need to use js to insert the messy html/css (in my case I use it to view emails)
<iframe class="my-frame" width="100%" height="100%" src="about:blank"></iframe>
and js:
const frame = document.querySelector('.my-frame');
frame.contentWindow.document.open('text/html', 'replace');
frame.contentWindow.document.write(hereGoesYourMessyHtmlCss);
frame.contentWindow.document.close();
Is there a reason why you can't use a modal? That would allow you to force a new request and make the page render how you'd want it to by not applying your general stylesheet while at the same time keeping your user on the desired page. Of course, it doesn't display the element inline so-to-speak, but it's nearly functionally equivelent.
Cutting and pasting raw HTML presents too many security problems, in my opinion. Never trust user's input. Even when the content is entirely benign, next week the designer of newsletter might decide to change their formatting or incorporate some javascript and you'll be responsible for anything that might go wrong.
Therefore I would implement a parser that would drop anything but the content part and leave only b, a, h*, blockquote and similar simple elements, like the ones allowed in forum posts, as well as their styles. After that, you can display it as a normal post in a CMS. I don't see any reason why that should look differently.
As for how to isolate that from your other CSS, you don't really need to if you are careful that all of CSS rules of your CMS apply to elements with specific classes. Alternatively, do a CSS reset for your posts:
.post p {
margin: 0;
...
.post /* all the standard CSS reset rules preceded with .post */
and then
<div class="post"> content parsed from your CMS </div>
Another option that I haven't used myself but am looking to possibly leverage in a similar situation is to use the Shadow DOM which is part of the Web Components spec. My main concern is that we still have some user's using IE 11 and while there seems to be support for polyfills it doesn't look like covering all browser's is real straight forward based on what I've read elsewhere.
Some details on how to use Shadow DOM to this effect can be found here and here. I've also created a small gist that I've created to demonstrate basic idea that I've been formulating as I learn about how the Shadow DOM works which I'll be updating as I learn more. Below you can see a snapshot of the content of that gist.
