I bought this book to get myself a little in the programming bath I have not yet fully completed I redid all the exercises one by one even simpler. VERY SIMPLE is to follow the HTML I was not familiar with CSS, I used to put my colors directly in the tags. Now I know better understand and structure the CSS. I regret that the parties on the videos, forms and tables are put to the end and not the result of ongoing I recommend taking your tests with different browsers (Chrome, IE, firefox). For those using other software notepad recommended (AceHTML 6 for example) that have a "internal browser" that can test a program without saving, be careful because the internal browser may not know all tags HTML 5 and we feel it gives nothing, so if this is the case you need to register and test in a real browser.
