1 00:00:00,510 --> 00:00:07,120 There are three types of CSI styles internal inline and external styles. 2 00:00:07,170 --> 00:00:15,880 This HDMI page illustrates an example of an internal style sheet and inline styles an internal style 3 00:00:15,880 --> 00:00:22,150 sheet simply means that the style sheet is contained in the same HMO document in which the styles are 4 00:00:22,150 --> 00:00:22,780 used. 5 00:00:23,640 --> 00:00:24,310 Here. 6 00:00:24,320 --> 00:00:35,060 We've defined a style sheet in between our head tags with three rules that will format the body the 7 00:00:35,070 --> 00:00:40,090 header one tags and the paragraph elements. 8 00:00:40,090 --> 00:00:47,150 This is an example of an internal style sheet we can easily convert this into an external style sheet 9 00:00:47,750 --> 00:00:57,210 by placing our style rules in a CSX file and linking to it to do so cut the styles rules out and delete 10 00:00:57,270 --> 00:00:58,230 the style tags 11 00:01:03,680 --> 00:01:09,320 now create a new file and paste the style rules into it. 12 00:01:11,420 --> 00:01:16,230 Now save this file as my styles dot the SS. 13 00:01:16,320 --> 00:01:24,080 You can use any name you want that's just an example. 14 00:01:24,100 --> 00:01:26,860 Make sure that the extension is a dot c SS file. 15 00:01:26,890 --> 00:01:28,300 Otherwise this will not work 16 00:01:31,950 --> 00:01:38,050 now when a switch back to the original file and we're going to link to our external style sheet using 17 00:01:38,050 --> 00:01:38,920 this line of code 18 00:01:42,990 --> 00:01:46,950 we can confirm that it worked by previewing the file in our web browser 19 00:01:51,570 --> 00:01:54,800 and you can see that all the styles are still applied. 20 00:01:55,050 --> 00:01:59,670 In addition to internal and external install sheets we also have inline C Ss 21 00:02:02,770 --> 00:02:09,080 with inline C Ss the style rules are added directly inside the element. 22 00:02:09,160 --> 00:02:14,530 For example here we have a paragraph element with two inline rules. 23 00:02:14,530 --> 00:02:23,550 Style is equal color blue and font size thirty five we can see in our web browser that the style rules 24 00:02:23,670 --> 00:02:32,820 have been applied to this paragraph of text the text size is 35 pixels and the color is blue using inline 25 00:02:32,820 --> 00:02:36,480 rules is normally not a good practice because it's inefficient. 26 00:02:36,840 --> 00:02:43,290 If we used inline rules on all our pages we would need to individually open each one and edit the rule 27 00:02:44,380 --> 00:02:51,730 inline rules also cause unnecessary repetition and increase the length of the HMO code when possible 28 00:02:52,330 --> 00:02:53,820 use external style sheets.
