1 00:00:00,110 --> 00:00:04,120 I wanna go ahead and take a look at the resources panel, which 2 00:00:04,120 --> 00:00:07,860 is similar to the elements panel, but 3 00:00:07,860 --> 00:00:11,390 we can actually look at some of the assets that are being loaded in. 4 00:00:12,950 --> 00:00:19,710 So if we twirl open our directory here, you can go ahead and click on one of these 5 00:00:19,710 --> 00:00:25,530 fonts, and you'll see that it actually displays the font right over here. 6 00:00:25,530 --> 00:00:29,650 So we can see A through Z in terms of capital 7 00:00:29,650 --> 00:00:32,860 letters, and we can also see A through Z in lower case. 8 00:00:32,860 --> 00:00:34,960 And we can see all ten numbers. 9 00:00:36,000 --> 00:00:42,072 If we click on, images over here, we can see what each one of these images looks 10 00:00:42,072 --> 00:00:47,806 like, and it will give us a couple of bits of information about the image. 11 00:00:47,806 --> 00:00:50,842 So, we can see the image against a transparent background. 12 00:00:50,842 --> 00:00:52,692 So we can see, you know, what 13 00:00:52,692 --> 00:00:56,030 the transparency actually looks like on that image. 14 00:00:56,030 --> 00:00:59,400 We can see the name of the file and the file type. 15 00:00:59,400 --> 00:01:03,150 We can also see the dimensions and file size for the image. 16 00:01:03,150 --> 00:01:07,440 So, that's especially important if you're building say, a 17 00:01:07,440 --> 00:01:11,550 website that's going to be ready for high resolution displays. 18 00:01:11,550 --> 00:01:14,170 You wanna be able to see the dimensions of the image. 19 00:01:14,170 --> 00:01:16,280 And if you're trying to optimize your website, 20 00:01:16,280 --> 00:01:18,820 you'll wanna look at the file size as well. 21 00:01:18,820 --> 00:01:21,820 We'll get a little bit more into optimization using some of the 22 00:01:21,820 --> 00:01:26,560 other panels later, but this is a good way to see file size. 23 00:01:26,560 --> 00:01:29,720 Again, we can see the mime type or file type. 24 00:01:29,720 --> 00:01:34,180 And then we can see the URL, that this image is coming from. 25 00:01:34,180 --> 00:01:37,720 So this is really handy if you have a broken image on 26 00:01:37,720 --> 00:01:41,280 the page, and you wanna try to trace where it actually is showing 27 00:01:41,280 --> 00:01:47,010 up, and whether or not you have the file path correct on your website. 28 00:01:48,430 --> 00:01:50,350 We can also look at style sheets here. 29 00:01:51,530 --> 00:01:53,440 So we can go ahead and see what 30 00:01:53,440 --> 00:01:56,980 all these style sheets look like, that's pretty nifty. 31 00:01:56,980 --> 00:02:01,070 And then we can go ahead and look at the HTML itself. 32 00:02:01,070 --> 00:02:06,450 Now all of these panels are linked together 33 00:02:06,450 --> 00:02:07,340 in some way or another. 34 00:02:07,340 --> 00:02:12,320 So, for example, if we go over to the elements panel again, and we 35 00:02:12,320 --> 00:02:17,220 see some styling being applied and we want to look at it in more detail. 36 00:02:17,220 --> 00:02:19,270 We can go ahead and click on the right side 37 00:02:19,270 --> 00:02:24,070 here, and it will bring us over to the sources panel. 38 00:02:25,340 --> 00:02:29,900 And, here you can see what that source actually looks like. 39 00:02:29,900 --> 00:02:31,610 So we'll look at the sources panel in 40 00:02:31,610 --> 00:02:32,750 a little bit more detail. 41 00:02:33,980 --> 00:02:37,360 But, that's very similar to the resources panel, and the elements panel, 42 00:02:37,360 --> 00:02:39,850 in that you can see what the HTML and the CSS looks like. 43 00:02:42,130 --> 00:02:46,450 So, down here, you'll notice a couple of other pieces here. 44 00:02:46,450 --> 00:02:50,390 There's Web SQL, IndexedDB, local storage, 45 00:02:50,390 --> 00:02:54,120 session storage, cookies, and the application cache. 46 00:02:54,120 --> 00:02:57,640 This website doesn't have any cookies, now if we go ahead and click on it. 47 00:02:57,640 --> 00:03:01,720 It will actually, explicitly say that, this site has no cookies. 48 00:03:01,720 --> 00:03:04,591 And if we twirl out local storage, well 49 00:03:04,591 --> 00:03:08,091 there aren't any key value pairs stored here. 50 00:03:08,091 --> 00:03:11,528 We can go ahead and add key value pairs, if we want to. 51 00:03:11,528 --> 00:03:16,419 So, that's really nice if you're interacting with a JavaScript application 52 00:03:16,419 --> 00:03:19,120 and you want to go ahead and see what key value 53 00:03:19,120 --> 00:03:22,332 pairs look like in the application or you want to edit 54 00:03:22,332 --> 00:03:27,120 those key value pairs, add new ones, delete ones, and so on. 55 00:03:27,120 --> 00:03:30,330 That pretty much wraps things up for the resources panel. 56 00:03:30,330 --> 00:03:33,210 Next up, we're gonna take a look at the network panel and 57 00:03:33,210 --> 00:03:36,520 learn about a couple of ways that we can improve the performance of our page.
