Hubert, Perhaps, I expected you to read between the lines a little more. As in marios pointer to "dynamically create a CSS <https://www.google.com/url?q=https%3A%2F%2Ftiddlywiki.com%2F%23Q%253A%2520How%2520can%2520I%2520use%2520a%2520custom%2520field%2520to%2520style%2520a%2520tiddler%253F%3A%255B%255BQ%253A%2520How%2520can%2520I%2520use%2520a%2520custom%2520field%2520to%2520style%2520a%2520tiddler%253F%255D%255D%2520%255B%255BQ%253A%2520Is%2520there%2520a%2520way%2520to%2520create%2520dynamic%2520stylesheets%253F%255D%255D%2520%255B%255BQ%253A%2520What%2520if%2520a%2520tiddler%2520has%2520no%2520tags%253F%255D%255D&sa=D&sntz=1&usg=AFQjCNEIYFy5rz_ueUFPGI8NR6FNHluZrA>" see how the filter is used?, it is possible to have the filter use fields to decide when to make some css active.
For example in a tiddler tagged $:/tags/ViewTemplate <$list filter=[all[current]has[fieldname]]"> <style> css here </style> </$list> The CSS Will be silently "displayed" on any tiddler with a field "filename" that has a value. Be careful because this css will be valid on the whole page, that is where ensuring the CSS selectors target only elements in the current tiddler, you can use classes and styles in your css and in the tiddler ensure that you label things with the specific class. Also in a tiddler tagged $:/tags/ViewTemplate <$list filter=[all[current]has:field[fieldname]]"> <style> css here </style> </$list> Will be silently "displayed" on any tiddler with a field "filename" that exists with a value or not. Or other filters like [all[current]!has:field[fieldname]] On tiddler that do not have the field "fieldname" I am no expert in CSS but I think you may be able to see what I am saying. Please ask more Questions. Regards Tony On Thursday, December 12, 2019 at 8:26:21 PM UTC+11, Hubert wrote: > > Tony, > > I appreciate your efforts to assist me.
