They'll actually explain what the doctype is, and 15 00:01:17,180 --> 00:01:20,090 even show you a demo of what it does. 16 00:01:20,120 --> 00:01:27,890 You can read into this and get more familiar with it, but the general rule and the concept behind 'doctype' 17 00:01:28,220 --> 00:01:35,480 is that 'doctype' says to the browser, 'Hey just a heads up this file is going to use HTML5.' 18 00:01:35,560 --> 00:01:40,899 And we'll get into what HTML5, is but right now, HTML has evolved from back in the day when Tim 19 00:01:40,900 --> 00:01:48,069 Berners-Lee invented it, to where it is now. And it has developed and evolved so that it has a few more 20 00:01:48,070 --> 00:01:49,000 tags, 21 00:01:49,030 --> 00:01:55,919 it has a few more features, and this is the way for us to say, 'Hey, browser we're going to be using HTML5. 22 00:01:55,920 --> 00:02:02,829 So please make sure that you load the website properly.' And we'll get into what those new tags are and 23 00:02:02,830 --> 00:02:05,160 some of the new syntaxes. 24 00:02:05,180 --> 00:02:11,810 But again most likely in your day to day job you're going to be writing this at the top because we're 25 00:02:11,870 --> 00:02:16,330 writing in HTML5, if that ever changes and something new comes along, 26 00:02:16,430 --> 00:02:19,180 we might change this, but 'doctype' that's what it is. 27 00:02:19,290 --> 00:02:24,609 But the key concept here is that I really want you to start Googling, at any time you see in my videos, 28 00:02:24,610 --> 00:02:28,540 something that you don't fully understand or you want to dig a little bit deeper. 29 00:02:28,610 --> 00:02:34,489 You really want to grow those roots of your foundation so that you really understand how the landscape 30 00:02:34,490 --> 00:02:35,120 works. 31 00:02:35,140 --> 00:02:35,520 OK. 32 00:02:35,660 --> 00:02:42,440 So I just wanted to get that concept across that as a developer, you really want to understand 33 00:02:42,530 --> 00:02:46,920 how things work and what they mean, and you'll come across in your day to day 34 00:02:46,970 --> 00:02:51,670 many things that it's very easy to just, on the surface copy and paste, 35 00:02:51,680 --> 00:02:56,470 or just look at an example and do it without fully understanding what it does. 36 00:02:56,540 --> 00:03:03,679 But the developers that get really really good salaries, really good jobs, and are considered 'senior developers' 37 00:03:03,680 --> 00:03:07,720 are the ones that fully understand all the meaning behind the things that they do. 38 00:03:07,730 --> 00:03:12,850 We're going to be taking that throughout the course and making sure that we develop those fundamentals. 39 00:03:12,890 --> 00:03:17,560 But any time, like I said, you have any questions or you don't understand something fully, 40 00:03:17,570 --> 00:03:24,169 I do encourage you to Google and get the answers because there's a ton of free resources out there for 41 00:03:24,170 --> 00:03:28,700 you to get fully, fully comfortable with the topic. 42 00:03:29,030 --> 00:03:30,210 I'll see you in the next one. 4988
