There’s a few problems - it’s waaaay too big. I really want to get rid of the surrounding black border and reformat the ‘STICKERS COLLECTED’ to make it much less bulky. And I would love to add rounded corners. I’m also just trying to see what all I can change to experiment with as I’d like to really overhaul the whole thing, but I’m not sure how to do more than change the font color and even that sometimes gets wonky.
3. Color change. The black border around the pumpkin is actually the background for the dialog box so you can use this to set both it and the dialog bar to the same color:
If you have something you want to change the styling for onscreen in your browser, just right-click on it, choose “Inspect” (or whatever your browser calls that option), and that will open up the browser’s Developer Tools window (you may need to click the “…” button there and choose to switch the “Dock side” to the bottom of the screen to get a better view of that window).
From the Developer Tools window you can use the “Elements” and “Styles” sections to see the HTML and CSS styles, respectively. With that, you can find the HTML elements, their IDs and classes, and how they’re currently styled. You can mess around with the styling there until you get things to look the way that you want, and then simply copy those changes to your game’s Stylesheet section to implement those changes. (I’d recommend doing this in Firefox, since it helpfully marks any CSS changes you make with a green line for you, so you don’t have to remember which things you’ve changed/added.)
