I don’t start in Photoshop I start in illustrator way faster, way more flexible and more accurate
CSS is horribly cumbersome to design in visually, it reminds me of doing mockups its Quark its fine if you already know what you want it to look like but if you want to just play around with elements until you get the look you want its very limiting

you will find going right to html that your designs will start to look very similar because you’ll want reuse code

I remember working for large ad agency and they insisted that a photoshop specialist do all the photoshop work for my designs i could do it myself but they didn’t want the tool to limit my creativity this took me a long time to accept but now I understand
