"What is CSS?"

Hello Marc Re,

Well , im not sure whats your problem but ill try to help you. Css is Cascading Styling Sheet, there is a tutorial "CSS Foundation:" and you will get it there , for now you need to learn HTML with is basic , the most basic.

Imagine that HTML is a house, you build a house with HTML, you say where the doors will be, you say how many flats will it have , how many rooms will it have and with css, you paint the house, you say where the door should be build , how bright should be inside the house etc..With CSS you ad a style to your website, HTML its just text etc.. and with CSS you make look how you want, eg you can make side bar , header, footer whatever .. Later on , when you learn all this on good level , you have JS with is for interactivity so dont get put of with HTML/CSS because you just style your page with it . And PHP is server language for passwords , login etc.. And when you make a website in workspace, you could or even should copy it to a text editor. I recomend sublime text2 and notepad ++ , you can also use notepad but save it as index.html and css save as main.css . This way you will have your code on pc and will be safe.

BDW ifthe code doesnt work, check each line two times letter by letter and if it still doesnt work , just re write all the code from tutorial.

Hope it helped you :)

Hey Mark, Your preview appears to be working fine now, hope you managed to carry on with your lessons unimpeded. If it happens again, a backup plan would be to copy all your code into a text editor (such as notepad) save the file names the same as on your workspace, and then open index.html in your web browser, that's what I will do if I encounter the same issue. Hope this helps!
