Look what I just realized! Paste the following into a tiddler. You might want to play around with the width of the story river also:
So the text starts out with some unsignificant stuff of no importance. But then... <span class="encircle">this is the really important stuff inside the text that really needs highlighting in some way so it is encircled as if it was done with a marker pen! </span> And then then unimportant text can continue afterwards as if nothing happened.
<style>
.encircle {
outline:5px solid #ff000080;
outline-offset:2px;
border-radius:50%;
}
</style>
<good>So the text starts out with some insignificant stuff of no importance. But then... <bad>this is the really important stuff inside the text that really needs highlighting in some way so it is encircled as if it was done with a marker pen! </bad> And then then unimportant text can continue afterwards as if nothing happened.</good>
<style>
bad {
outline:1px solid #d14;
outline-offset:-2px;
border-radius:5px
}
bad:before {
content: " X ";
color:#d14;
}
good {
outline:1px solid #0a0;

good:before {
