I've just created my first website (congratulate me). And I want to upload it but although I don't have access to many different computers, I've opened my webpages up on google chrome, internet explorer and firefox and the style looks slightly different. So apparently what I need to do is create 3 different versions (in term of the style) and open up different versions depending on what browser the viewer is using. Is this correct? Hopefully I can find a good tutorial online for this.
I remember hearing somewhere that depending on different pixels each computer is using, things look different or something - I'm not too sure. Can someone tell me if I'll have to change the "px" stuff around in all of my code. Please tell me this isn't true!
I use mysql to store data in and on top of all the code files i connect to it with
$con = mysql_connect("localhost","name","password");
when i upload my site would people not just be able to go to view page source then use that to hack into my database :/
Currently in the <a href> links I link to pages like "./images/whatever.jpg". Once I put the website online would I need to change all of these links in accordance with whichever hosting provider I'm using.
Sorry it was kind of long but if you have time please brief me on these topics. Will be appreciated!
