Times have changed on the internet and back when you thought coding couldn't be made any easier for you to style your websites you were mistaken. CSS has taken the basic HTML coding to the next level and again when you thought your coding couldn't look any neater, you were wrong. CSS doesn't need the likes of HTML tables and what a fantastic advantage CSS is and I'll explain why.
In the old days of HTML coding, website designers would need to use the HTML tables tags which resulted in the coding looking messy. Not only that, without the use of CSS (Cascading Style Sheets) coders would be coding for a lot longer which meant a lot of time was wasted. This all changed when CSS was introduced and don't get me wrong, a lot of cross browser problems still occur but it's such a good transformation to the web design industry all this is worth it.
Cross browser compatibility problems do occur a lot more frequently with the use of CSS because some browsers render the CSS functions differently and cause the website to be displayed differently between most common browsers such as IE7, IE8 and FF. There are many myths and different information on the internet which discusses cross browser compatibility and how coders should only code for the latest browers which are the likes of IE8, FF, Google Chrome, Opera, Safari etc. Little of this information is true and if you do only code for the latest browsers, a large proportion of internet viewers still use Internet Explorer 6 so you're not allowing for a huge amount of internet users who can't view the sites you code properly.
There are lots of hacks and different CSS functions you can use to allow for the whole internet browsing industry and all you need to do is learn to code for one browser such as Firefox (as recommended by professionals, given that IE7 doesn't compile the codes correctly) then once you've mastered to code for one browser you can apply the specific changes so your site is viewable in all website browsers and on all systems.
