Checking for browser compatibility

From: Creating a First Web Site with Dreamweaver CS4

Video: Checking for browser compatibility

So once you have your website created, the next step is really moving into the testing phase. Everything again looks great and really all I have been doing up till this point is just going to File and previewing it in a browser and I have actually just been using Firefox and this is the sort of the extent of my testing so far. I've been able to check out sort of these different pages, and it seems like a pretty good site. But again, this is just in Firefox 3.0.1 on a Mac and really I want to make sure it's going to look good in all browsers on all machines.

Checking for browser compatibility

So once you have your website created, the next step is really moving into the testing phase. Everything again looks great and really all I have been doing up till this point is just going to File and previewing it in a browser and I have actually just been using Firefox and this is the sort of the extent of my testing so far. I've been able to check out sort of these different pages, and it seems like a pretty good site. But again, this is just in Firefox 3.0.1 on a Mac and really I want to make sure it's going to look good in all browsers on all machines.

So, that's really my next step is to check the browser compatibility of this site and I'm just going to go through page by page and check this out. Instead of previewing in a browser, I'm going to check the browser compatibility for this page. And what it does is it opens up this Compatibility panel and it says no issues were detected. So it's working out quite well, and it does tell me, hey if you want to get started, you can always use this little arrow over here to check for browser compatibility that way, but in general I don't get any errors with this page.

Let's go to the Contact page. So from here, I can go to this arrow if I want to and Check Browser Compatibility on the Contact page, no issues were detected. Let's go to the About page. The About page is a little more complex because it does have this Spry Accordion. Let's check its browser compatibility and it doesn't have any issues. You are probably wondering now, what browsers it's checking against. Well, go down to Settings to view all of the browsers I'm currently targeting.

Everything from Firefox to Internet Explorer on Mac and PC, Netscape, Opera and Safari. They are all there, even the versions are there as well. So, this is what I'm checking this against. But this is really nice. I don't have to have all of this browsers loaded on my Mac, nor do I even need a separate machine to test these browsers on, this does it for me. I really appreciate this as well. Portfolio page gets a little more advanced, because again, we have this gallery, so let's see how this one fairs.

Check Browser Compatibility, and it goes through and it finds two errors. The great thing about is it says, hey you know what? Found two errors on line 17 in the Lightbox Cascading Style Sheet and this error only affects Netscape 8.0, which let's be honest not many people use that browser. The second one is on line 17 and affects sort of multiple browsers. So, let's just check that up. Let's go to lightbox.css.

Let's go down to line 17, there we are. And really, this is just talking about the overlay position. The left is set to 0, which it automatically defaults the left side to zero anyways, so I would consider this an unnecessary CSS property. So, I can just remove that entirely. So, let's run this again. See if we get any other errors. We do get a couple more errors so let's check those out. Line 57, and really this is the process of finding the error or getting and again, another scenario, this outline is set to None, but if I'm trying to set an outline, I would set it to something.

By default it's set to None. So, I'll just remove that entirely as well. Let's check the browser compatibility again, and lastly we have this unsupported property, this zoom property on line 61, so right down here, it says zoom. Well, it does affect multiple browsers, but it's not going to hurt anything if I have this in there. I would rather have this sort of zoom effect with the gallery, work in some browsers, then remove it completely. The more advanced browsers will get this experience and the older browsers won't, and I'm totally comfortable with that, but I just want to be aware of this going on.

So, I'm just going to leave that in there entirely and I can go ahead and save this page. I can go ahead and preview this in a browser maybe one more time and just make sure everything is going to be fine. But again, that's the job of checking for browser compatibility, making sure this works without really having all of those browsers on your system. But really the testing phase is going to consist of checking this in multiple browsers on multiple machines, and it's nice that Dreamweaver gives me that capability from within the interface.
