CSS gives Web designers control over the appearance of their web sites by separating the visual presentation from the content. It lets them easily make minor changes to a site or perform a complete overhaul of the design. In CSS Web Site Design, instructor and leading industry expert Eric Meyer reviews the essentials of CSS, including selectors, the cascade, and inheritance. The training also covers how to build effective navigation, how to lay out pages, and how to work with typography, colors, backgrounds, and white space. Using a project-based approach, Eric walks through the process of creating a Web page, while teaching the essentials of CSS along the way. By the end of the training, viewers will have the tools to master professional site design. Exercise files accompany the training videos.
So in this video, we're just going to take a quick look at horizontal alignment of text. This is a way that you can effect the presentation of text without having to mess around with things like font faces and font families and font weights and other font stuff. So, as an example, we could, let's say, right align all of our paragraph text, why not, seems like fun, so we just say text-align right. So for paragraphs the text will be right aligned and it all goes over the right side.
Now the very avant-garde, not necessarily the way that people who read English or other Western languages are used to seeing it, but there is none the less, and what happens here is that each line of text is shifted over so that its right edge gets lined up with the right edge of its parent element. So within each paragraph there are a number of lines of text. Let's take the second paragraph that starts "It was in the 16th century that the Portuguese missionaries," has three lines of text and within that paragraph box each of those lines of text gets shifted over so that the right edge of each text line is lined up with the right edge of the paragraph and more specifically with the right content edge of the paragraph.
If there are any padding on the paragraph then the alignment point would be inside of the padding, but we'll talk about padding in a different chapter actually. For now, just take that and you'll learn more later. There's also left aligning. As you might guess any left to right languages like English or Spanish or French or really any Roman-based language you're going to have left alignment as the default because it's a left to right language, but in text, aligned left is the default value and left aligned languages like English, and so on.
We can text-align right and could do text-align Center in which each box, each line box is centered, between the two edges, but there is something interesting to notice here which is the wine boxes next to the image of the tea kettle are centered in the space that they have available to them. That's completely in keeping with what we would expect and is in keeping with the CSS specifications, but basically each of those lines of text is centered between the space that has available next to that image of the tea kettle and the other edge of the paragraph. So it was in the line, "It was in the 16th century that Portuguese missionary were seduced by tea's flavor," align it's centered along with the center point of the distance between the image and the edge of the paragraph. So, how much space a line has it sort of centers itself in that space. The same thing with all the others is just that for example the first line of text, which starts "the history of tea extends so far into the past," it doesn't have anything to either side of it so it just centers itself within left right edges of this paragraph.
There's one other text alignment value that we can use for text align and that's justify. Now what this does is it justifies text, which is a little easier to show then it is to explain verbally so here's what it does. It evens out effectively each line of text except for the last one in the given element so that the text goes from one edge, all the way to the other. You can see how there's this sort of neat lining up of the text edges along each left and right side.
This is fairly common in print and is very tempting to do this. It's very, very tempting to go for fully justified text, but there are some potential drawbacks. One is that because you can't necessarily control exactly what's going to happen, if you get really narrow text. Notice there's a line right near the top of the tea kettle, before tea quickly spread and there're these big gaps between the words, there's also one near the bottom, the intricate customs which, line and these big gaps between words and that's what can happen with fully justified text.
You can wind up with some very strange effects some that aren't very nice. Here's one, "It was in the 16th century that Portuguese missionaries," is a huge gap in there. Now this is not generally a problem if you have very wide browser windows, but you don't have control of your browser window size. So this is one of the reasons why full text justification tends not to be used. The one exception there is in print. There are people who will oftentimes do fully justified text in print, that's for Chapter 9.
So anyway, that's one of the text alignment you can do justify, which goes along with right left and center and these are all as we saw, horizontal alignments of text. What we'll talk about in the next video is the vertical alignment of text.
