16 00:00:44,396 --> 00:00:47,563 CSS stands for cascading style sheets. 17 00:00:48,853 --> 00:00:53,020 CSS defines exactly how HTML elements should look. 18 00:00:53,971 --> 00:00:56,854 It allows us to make a clear separation 19 00:00:56,854 --> 00:00:59,611 line:15% between content and style. 20 00:00:59,611 --> 00:01:02,778 line:15% HTML is the content and CSS is style. 21 00:01:06,233 --> 00:01:09,633 These two images show the exact same HTML 22 00:01:09,633 --> 00:01:10,988 with the only difference 23 00:01:10,988 --> 00:01:13,046 that the website on the left side 24 00:01:13,046 --> 00:01:15,869 has not been formatted with CSS yet. 25 00:01:15,869 --> 00:01:19,306 It's just bare HTML, which doesn't look very good, 26 00:01:19,306 --> 00:01:20,139 of course. 27 00:01:22,254 --> 00:01:25,164 So how are we gonna use CSS in practice? 28 00:01:25,164 --> 00:01:28,224 There are three ways to use CSS. 29 00:01:28,224 --> 00:01:31,034 First, we can write CSS code 30 00:01:31,034 --> 00:01:35,107 right inside an HTML tag using the style attribute. 31 00:01:35,107 --> 00:01:39,205 Second, we can write CSS code in the head section 32 00:01:39,205 --> 00:01:40,872 of an HTML document. 33 00:01:41,713 --> 00:01:45,880 And third, CSS code can be put into an external file. 34 00:01:46,811 --> 00:01:49,654 And this is what we're actually going to do. 35 00:01:49,654 --> 00:01:51,311 Remember what I said about 36 00:01:51,311 --> 00:01:55,270 how CSS allows us to separate content from style?
