Is there any possibility to create CSS definition for any element with the class "icon-" and then a set of letters but not numbers.
According to this article something like:
[class^='/icon\-([a-zA-Z]+)/'] {}
should works. But for some reason it doesn't.
In particular I need to create style definition for all elements like "icon-user", "icon-ok" etc but not "icon-16" or "icon-32"
Is it possible at all?
CSS attribute selectors do not support regular expressions.
If you actually read that article closely:
Regex Matching Attribute Selectors
They don’t exist, but wouldn’t that be so cool? I’ve no idea how hard it would be to implement, or how to expensive to parse, but wouldn’t it just be the bomb?
Notice the first three words. They don't exist. That article is nothing more than a blog post lamenting the absence of regex support in CSS attribute selectors.
But if you're using jQuery, James Padolsey's :regex selector for jQuery may interest you. Your given CSS selector might look like this for example:
$(":regex(class, ^icon\-[a-zA-Z]+)")
I answered this one on facebook but thought I'd best share here too :)
I haven't tested this so don't shoot me if it doesn't work :) but my guess would be to excplicitly target elements that contain the word icon in the classname, but to instruct the browser not to inlcude those classes containing numbers.
Example code:
div[class|=icon]:not(.icon-16, .icon-32, icon-64, icon-96) {.....}
Reference:
attribute selectors... (http://www.w3.org/TR/CSS2/selector.html#attribute-selectors):
[att|=val]
Represents an element with the att attribute, its value either being exactly "val" or beginning with "val" immediately followed by "-" (U+002D).
:not selector...

I tested my previous solution and can confirm that it DOES NOT work (see comment from BoltClock). This however does:
OP: "In particular I need to create style definition for all elements like "icon-user", "icon-ok" etc but not "icon-16" or "icon-32""
The required CSS code would look something like this:
/* target every element were the class name begins with ( ^= ) "icon" but NOT those that begin with ( ^= ) "icon-16", or "icon-32" */
*[class^="icon"]:not([class^="icon-16"]):not([class^="icon-32"]) {.....}
or
/* target every element were the class name begins with ( ^= ) "icon" but NOT those that contain ( *= ) the number "16" or the number "18" */
*[class^="icon"]:not([class*="16"]):not([class*="32"]) { ...... }
Test code:
<!DOCTYPE html>
<html>
<head>
<style>
div{border:1px solid #999;margin-bottom:1em;height:100px;}
*[class|=icon]:not([class|=icon-16]):not([class|=icon-32]) {background:red;color:white;}
</style>
</head>
<body>
<div class="icon-something">
<h4>icon-something</h4>
<p><strong>IS</strong> targeted therfore background colour will be red</p>
</div>
<div class="icon-anotherthing">
<h4>icon-anotherthing</h4>
<p><strong>IS</strong> targeted therfore background colour will be red</p>
</div>
<div class="icon-16-install">
<h4>icon-16-install</h4>
<p>Is <strong>NOT</strong> targeted therfore no background colour</p>
</div>
<div class="icon-16-redirect">
<h4>icon-16-redirect</h4>
<p>Is <strong>NOT</strong> targeted therfore no background colour</p>
</div>
<div class="icon-16-login">
<h4>icon-16-login</h4>
<p>Is <strong>NOT</strong> targeted therfore no background colour</p>
</div>
<div class="icon-32-install">
<h4>icon-32-install</h4>
<p>Is <strong>NOT</strong> targeted therfore no background colour</p>
</div>
<div class="icon-32-redirect">
<h4>icon-32-redirect</h4>
<p>Is <strong>NOT</strong> targeted therfore no background colour</p>
</div>
<div class="icon-32-login">
<h4>icon-32-login</h4>
<p>Is <strong>NOT</strong> targeted therfore no background colour</p>
</div>
</body>

In a page, I have a rendering with a placeholder, Offcanvas.cshtml
<div data-ads-offcanvas-id="#Model.Id" class="ads-offcanvas #Html.GetCssStyles()">
#{
<a data-ads-offcanvas-trigger-id="#Model.Id" class="ads-close-button" href="#0">X</a>
#Html.Sitecore().Placeholder(LayoutHelper.GetPlaceholder(Placeholders.AccordionSection, Model.Id))
}
and inside that rendering, I plan to put another rendering with a placeholder named Modal.cshtml
<div data-ads-modal-container="#Model.Id" class="ads-modal-container">
<div class="ads-modal-dialog">
<div class="ads-close-box">
<a data-ads-modal-id="#Model.Id" href="#0">X</a>
</div>
<div class="ads-modal-content">
#Html.Sitecore().Placeholder(LayoutHelper.GetPlaceholder(Placeholders.AccordionSection, Model.Id))
</div>
</div>
So it looks like:
-Offcanvas
+-Modal
++-Text content
When I put text content inside the Modal rendering, the content is not rendered. I'm guessing that it only renders that first few renderings and fail to do so when the renderings became highly nested.
Is there a solution to render components to the very-most child?
Thanks guys!
EDIT:
Here's the code for GetPlaceholder:
public static string GetPlaceholder(string name, Guid id)
{
return $"{name}_{id}";
}
Dynamic placeholders are a bit more complicated than generating a unique placeholder key. The generated key still needs to resolve back to a real placeholder that is defined in Sitecore.
Check out the Integrated Dynamic Placeholder module.
This will provide an Html helper similar to your current implementation:
#Html.Sitecore().DynamicPlaceholder("[Placeholder Name]")
I basically want to scrape Litigation Paralegal under <h3 class="Sans-17px-black-85%-semibold"> and Olswang under <span class="pv-entity__secondary-title Sans-15px-black-55%">, but I can't see to get to it. Here's the HTML at code:
<div class="pv-entity__summary-info">
<h3 class="Sans-17px-black-85%-semibold">Litigation Paralegal</h3>
<h4>
<span class="visually-hidden">Company Name</span>
<span class="pv-entity__secondary-title Sans-15px-black-55%">Olswang</span>
</h4>
<div class="pv-entity__position-info detail-facet m0"><h4 class="pv-entity__date-range Sans-15px-black-55%">
<span class="visually-hidden">Dates Employed</span>
<span>Feb 2016 – Present</span>
</h4><h4 class="pv-entity__duration de Sans-15px-black-55% ml0">
<span class="visually-hidden">Employment Duration</span>
<span class="pv-entity__bullet-item">1 yr 2 mos</span>
</h4><h4 class="pv-entity__location detail-facet Sans-15px-black-55% inline-block">
<span class="visually-hidden">Location</span>
<span class="pv-entity__bullet-item">London, United Kingdom</span>
</h4></div>
</div>
And here is what I've been doing at the moment with selenium in my code:
if tree.xpath('//*[#class="pv-entity__summary-info"]'):
experience_title = tree.xpath('//*[#class="Sans-17px-black-85%-semibold"]/h3/text()')
print(experience_title)
experience_company = tree.xpath('//*[#class="pv-position-entity__secondary-title pv-entity__secondary-title Sans-15px-black-55%"]text()')
print(experience_company)
My output:
Experience title : []
[]
Your XPath expressions are incorrect:
//*[#class="Sans-17px-black-85%-semibold"]/h3/text() means text content of h3 which is child of element with class name attribute "Sans-17px-black-85%-semibold". Instead you need
//h3[#class="Sans-17px-black-85%-semibold"]/text()
which means text content of h3 element with class name attribute "Sans-17px-black-85%-semibold"
In //*[#class="pv-position-entity__secondary-title pv-entity__secondary-title Sans-15px-black-55%"]text() you forgot a slash before text() (you need /text(), not just text()). And also target span has no class name pv-position-entity__secondary-title. You need to use
//span[#class="pv-entity__secondary-title Sans-15px-black-55%"]/text()
You can get both of these easily with CSS selectors and I find them a lot easier to read and understand than XPath.
driver.find_element_by_css_selector("div.pv-entity__summary-info > h3").text
driver.find_element_by_css_selector("div.pv-entity__summary-info span.pv-entity__secondary-title").text
. indicates class name
> indicates child (one level below only)
indicates a descendant (any levels below)

Yes yes, I know, "don't parse HTML with Regex". I'm doing this in notepad++ and it's a one-time thing so please bear with me for a moment.
I'm trying to simplify some HTML code by using some more advanced techniques. Notably, I have "inserts" or "callouts" or whatever you call them, in my documentation, indicating "note", "warning" and "technical" short phrases to grab the attention of the reader on important information:
<div class="note">
<p><strong>Notes</strong>: This icon shows you something that complements
the information around it. Understanding notes is not critical but
may be helpful when using the product.</p>
</div>
<div class="warning">
<p><strong>Warnings</strong>: This icon shows information that may
be critical when using the product.
It is important to pay attention to these warnings.</p>
</div>
<div class="technical">
<p><strong>Technical</strong>: This icon shows technical information
that may require some technical knowledge to understand. </p>
</div>
I want to simplify this HTML into the following:
<div class="box note"><strong>Notes</strong>: This icon shows you something that complements
the information around it. Understanding notes is not critical but
may be helpful when using the product.</div>
<div class="box warning"><strong>Warnings</strong>: This icon shows information that may
be critical when using the product.
It is important to pay attention to these warnings.</div>
<div class="box technical"><strong>Technical</strong>: This icon shows technical information
that may require some technical knowledge to understand.</div>
I almost have the regex necessary to do a nice global search & replace in my project from notepad++, but it's not picking up "only" the first div, it's picking up all of them - if my cursor is at the beginning of my file, the "select" when I click Find is from the first <div class="something"> up until the last </div>, essentially.
Here's my expression: <div class="(.*[^"])">[^<]*<p>(.*?)<\/p>[^<]*<\/div> (notepad++ "automatically" adds the / / around it, kinda).
What am I doing wrong, here?
You have a greedy dot-quantifier while matching the class attribute — that's the evil guy who's causing your problems.
Make it non-greedy: <div class="(.*?[^"])"> or change it to a character class: <div class="([^"]*)">.
Compare: greedy class vs. non-greedy class.
I'm trying to use gulp-uncss to remove unneeded CSS from a Zurb Foundation website.
Within the site I'm using Foundation's Equalizer to make two columns the same height. This works by adding a data- attribute to an element:
<div data-equalizer>
<div data-equalizer-watch>
<div>
<div data-equalizer-watch>
<div>
<div>
When the page loads Foundation determines the height of the two elements and injects an inline style to set the height of the elements to the greater of the two element heights. The result is:
<div data-equalizer>
<div data-equalizer-watch style="height: 256px;">
<div>
<div data-equalizer-watch style="height: 256px;">
<div>
<div>
When I add gulp-uncss to my gulpfile.js the Equalizer no longer works. The data- attributes are still present in the HTML file, but the inline styles are not added.
I've tried using the ignore option in gulp-uncss to ignore height but had no luck. The inline style is no longer added to HTML document.
Is there an option in gulp-uncss that will allow the equalizer to do it's job?
I was able to get gulp-uncss working using the ignore parameter in UnCSS.
Adding:
ignore: [/^meta.foundation/, /f-topbar-fixed/, /contain-to-grid/, /sticky/, /fixed/]
to uncss() kept all the necessary CSS. The most important of these is /^meta.foundation as this allows the Foundation JS to inject the styles. The remaining values /f-topbar-fixed, contain-to-grid, /sticky/ and /fixed/ are all specific to the Foundation JS modules I'm using. The above work for a .sticky topbar.
If you're using other JS modules you'll need to determine what classes are being injected and add those to the the ignore array.
Got a very particular problem here:
I've been developing a tumblr-hosted site locally, using the API to pull in posts without having to copy and paste the project into tumblr a million times. I decided I liked the API better and would just use that in production, but now that it's time to deploy I realize that I have to go back to the custom theme, {block:Posts} method.
I have the post feeding into a Cycle2 slideshow, with 3 slides containing 3 posts each for a total of 9 playlists viewable without going back to the archive. This method works perfectly with the api, but is getting messed up in the custom theme. Here's my current code:
<div class="cycle-slideshow">
{block:Posts}
{block:Text}
<div class="slide-wrapper">
<div class="post">
{block:Post1}
{block:Title}<h2>{Title}</h2>{/block:Title}
<div class="blog_item">
{Body}
</div>
{/block:Post1}
</div>
<!--two more posts before end of slide... -->
</div>
{/block:Text}
{/block:Posts}
</div> <!--end of slide wrapper - 2 more of these before end of slideshow div..
I also tried scrapping the post numbers, but still no dice. In tumblr's docs, they say that
Example: {block:Post5}I'm the fifth post!{/block:Post5} will only be rendered on the fifth post being displayed.
I'm wondering if "being displayed" refers to the html visibility of the post, and if so, if that's interfering with the cycle plugin? The results are one ill-formatted post per slide, and then after cycling through 2 blank slides, the next oldest post takes its place. I'll be pleasantly surprised if anybody has ever had a similar problem but I would kill for some advice. Here's the development site for reference (and the second carousel is working because it's still hooked up to the api). thanks!!
Generally speaking, the following code is what you'd want to have 3 slideshows with 3 posts each.
Note that in the Additional Settings on the Customize screen, you'd have to set the post count to 9 per page in order for this to work properly. I wrapped it in an Index Page block, otherwise this is going to look nasty on a Permalink Page.
{block:IndexPage}
{block:Posts}
{block:Post1}<div class="cycle-slideshow">{/block:Post1}
{block:Post4}<div class="cycle-slideshow">{/block:Post4}
{block:Post7}<div class="cycle-slideshow">{/block:Post7}
<div class="slide-wrapper">
{block:Text}
<div class="post">
{block:Title}<h2>{Title}</h2>{/block:Title}
<div class="blog_item">
{Body}
</div>
</div>
{/block:Text}
{block:Photo}
...
{/block:Photo}
...
</div>
{block:Post3}</div>{/block:Post3}
{block:Post6}</div>{/block:Post6}
{block:Post9}</div>{/block:Post9}
{/block:Posts}
{/block:IndexPage}
However, if you're wanting 3 slideshows with the post types split between the slideshows, the code would look more like the following.
Note that in this scenario, if you were to have 4 texts posts out of 9, all 4 text posts would end up in the Text slideshow. You'd have to use Javascript or CSS to remove or hide the additional posts if you're very strict about your 3.
{block:IndexPage}
<div class="cycle-slideshow">
{block:Posts}
{block:Text}
<div class="slide-wrapper">
<div class="post">
{block:Title}<h2>{Title}</h2>{/block:Title}
<div class="blog_item">
{Body}
</div>
</div>
</div>
{/block:Text}
{/block:Posts}
</div>
<div class="cycle-slideshow">
{block:Posts}
{block:Photo}
<div class="slide-wrapper">
...
</div>
{/block:Photo}
{/block:Posts}
</div>
{/block:IndexPage}
If you need me to clarify anything, let me know.
