Hi, I tried to implement a partial solution to transclude selected lines of code from a tiddler contains the whole code. Then I transcluded the whole code with those selected lines. The whole code is opaque but those lines are clear with sharp contrast. This way one can show a code with few lines stand out to get the viewer attention.
To give a try 1. download attached example, 2. drop on https://tiddlywiki.com/prerelease/ (use prerelease which has the Highlight.js installed) 3. open test/code-lines and see how the code looks like You can do more examples by opening test/code-lines and editing the lines. *Note*: I am not happy with this solution, it seems a little tedious and low in performance (a lot of <pre><code> tags are created. What is the better solution. On Friday, January 8, 2021 at 11:10:31 AM UTC+3:30 Mohammad wrote: > Hi Eric, > > I came to this thread and found it very interesting.
