Specify css file in html

CSS rules are render-blocking so it's recommended to add style tags into the HTML documents so they download as soon as possible. We'll discuss render-blocking CSS shortly. No extra HTTP requests are required. I use this method on my website layout demos so when people view the source of the page they can see the HTML and the CSS code together.

Works great with dynamic styles: If you're using a database to generate page content you can also generate dynamic styles at the same time.

Blogger does this by dynamically inserting the colors for headings and other elements into the CSS rules embedded in the page. This allows users to change these colors from an admin page without actually editing the CSS in their blog templates. Disadvantages Embedded styles must be downloaded with every page request: These styles cannot be cached by the browser and re-used for another page.

Because of this, it's recommended to embed a minimal amount of CSS as possible. To do this, simply add a style attribute to the element then enter your rules as a single line of text a string of characters for the value. Here's how this looks:. Just change "newstyles" to the name of your CSS file and be sure to include the correct path to the file too.

But since css is the only stylesheet language used on the web, it is not only optional, but it is even a best practice not to include it. The media attribute is not visible in the example. It's an optional attribute that you can use to specify when to import a certain stylesheet.

This can be useful in case you want to separate the styles for different devices and screen sizes in different files. You would need to import each CSS file with its own link element.

Colors can be specified in CSS in several ways. There are about color names and the hexadecimal codes allow for over 16 million colors. Adding a touch of style explains more about these codes.

Step 3: adding fonts Another thing that is easy to do is to make some distinction in the fonts for the various elements of the page. If Helvetica is absent, Geneva, Arial and SunSans-Regular are quite similar in shape, and if none of these work, the browser can choose any other font that is serif-less. Now the main text has a different font from the heading.

Step 4: adding a navigation bar The list at the top of the HTML page is meant to become a navigation menu. Many Web sites have some sort of menu along the top or on the side of the page and this page should have one as well.

We will put it on the left side, because that is a little more interesting than at the top… The menu is already in the HTML page. On a real Web site, there should not be any broken links, of course. So we need to move the list to the left and move the rest of the text a little to the right, to make room for it. The CSS properties we use for that are 'padding-left' to move the body text and 'position', 'left' and 'top' to move the menu. There are other ways to do it.

But this one is OK for our purposes.
