Is there a way to markup webpages on the S3? In the stock browser or in Chrome, is there a way to markup webpages in different colours for notes etc.? It would be good if the marks show up everytime I open that webpage. If that's not possible, I could save it as an image.  

OS: 4.1.1
Samsung Galaxy S3
After giving thought to what geffchang said above, I came across with the app Skitch which can be used to highlight webpages as you wish. 

Added advantage for this app is you can directly synchronize your work with Evernote, a widely used note-taking app.
