Thank you guys!! I haven’t done the actual implementation yet, lol…but I wanted to say thank you. And yes, I should’ve specified that I was wanting the highlight effect to be static and click or hover-reliant and that I wanted it to be kinda ‘messy’ like a real highlighter might be. Fwiw, I also stumbled upon SVGBox site of vector icons, and he created several ‘pen brushes’. I included his tutorial and the brushes below.
