I'm using a demo version of Publishing Engine and have run into the following issue while creating PDFs

I'm testing the use of css variables and string-set and when referencing them in the css no value is returned.

Code: Select all

:root {
	string-set: effectiveDate "EFFECTIVE DATE";
	--effectiveDate: "EFFECTIVE DATE";
}

/* this one returns : TEST - Some more stuff - null */
.front-page > div.front-page-title > div {
	color: blue;
	font-size: 4rem;
	content: oxy_concat('TEST - ', 'Some more stuff - ', string(effectiveDate));
}

/* this one returns nothing */
.front-page > div.front-page-title2 > div {
	color: blue;
	font-size: 4rem;
	content: oxy_concat('TEST - ', 'Some more stuff - ', var(--effectiveDate));
}

I've tried the above without the oxy_concat
content: var(--effectiveDate); or content: string(effectiveDate)
both these return nothing.

Is this a limitation with the demo version?

Hello Mario,

This is not a limitation of the trial version, the string() function can only be used within a static context like page-margin boxes (defined within CSS @page at-rule). You can't use it at element level. If you use it in the correct context, you don't need to use oxy_concat() function, you can directly write each value:

Code: Select all

@page front-page {
  @top-left {
    content: 'TEST - ' 'Some more stuff - ' string(effectiveDate));
  }
}

You cannot use a variable neither as indicated in the CSS Validator warning: "Due to their dynamic nature, CSS variables are currently not statically checked".

If you want to add dynamic content in some elements you should take a look at the oxy_xpath() function, you can for example add the current date:

Code: Select all

*[class~="front-page/front-page-title"]::after{
  display: block;
  content: oxy_xpath('current-date()');
}

Julien

Thanks for the quick reply.
If I use oxy_xpath() can I use document()?

Hello Mario,

Yes you can, there is an example in the user guide.
