![]() Just as a period before the name tells us that the selector is a class, the pound sign (#) before the name lets us know that the selector is an ID. Now, notice that in addition to styling the element black and the h1 element and the Text-break class red, I styled the paragraph with the id attribute Green as… you know, green. Notice that the tag should always include the attribute type=”text/css.” That tells the ereader that this is standard CSS. As I said, it is placed in the section of the file, and would look something like this: The first is to add a block to your file. There are two ways to do this in any HTML document - including one of the files that makes up your ebook. These are the equivalent of the styles used in word-processing and page-layout apps - changing the style changes every part of the document to which the style has been applied. ![]() So how can you make your CSS styles more powerful and easier to edit? (I know, setting all of the text to orange Comic Sans seemed like such a good idea!) You can do all sorts of wonderful things when you apply styles inline - but when you do, they will only apply to those tags where they’re added, and they will always apply there, until you search through and change them. Since the declaration is inside a tag, it’s clear what the rule refers to. Notice that I don’t use a selector when using the style attribute. Now, that would only work if Garamond were actually installed on the ereader or embedded in the ebook, so I added the generic serif, which tells the ereader to use its default serif typeface. Likewise, if I were to want to make a particular section (or ) of text in Garamond, I would do this: (Remember: those quotes must be “straight,” not “smart” or “curly.”) If you want to apply a CSS style to just one HTML tag, you can do it inline by adding a style attribute to an HTML tag.įor example, if I were to want to center a particular paragraph, I could add style=”text-align:center” to the tag, like so: In a linked CSS file, either in the ebook itself or on the open internet.In a tag inside the at the top of the HTML file.Now there are three places you can place a CSS rule: I’ll get into more detail on some of the various rules that you care about in another post - sorry, this one is already complicated enough! Location, location, location That’s a lot simpler than it might at first look. So here’s an example from the stylesheet file Styles/Styles.css in the White Robes ebook that I linked to a couple of posts back: A declaration - that is to say, one or more properties defining how the selector(s) should display.An element with a particular ID (that is, having the attribute id=”whatever”). ![]() One or more class (that is, any elements that have been given the attribute class=”whatever”).One or more type of HTML element (that is, any instance of a particular tag:, ,, etc.).The Rule of LawĪll CSS really comes down to is a series of rules that define how a particular element (or kind of element) will look when an ereader displays it. It’s what allows you to add color, to change fonts and (within reason) typefaces, to define where and how images display, and much more. And in the last post, I’m going to talk about how to know which rules take precedence when.ĬSS was created to define the presentation style to any XML document - but it’s most common use is in conjunction with the HTML in web pages and, of course, in ebooks. In the second post, I’m going to look at some of the different properties that you can use to define how your ebook looks. This time round, I’m going to show you what CSS is and how to apply it. This is a somewhat complicated topic, so I am going to take three posts to cover it. While that may sound superficial, in fact learning to use CSS can have a profound impact on your ebook. If HTML is the blueprint, showing how an ebook (or a web page) should be laid out, Cascading Style Sheets (CSS) are the interior design, saying how everything should look.
