When learning the front-end, we should know that css adds various styles to html tags to tell the browser, so How to display the content inside these tags. Since css is used to add various styles to HTML, how to add css styles to HTML?
htmlThere are three ways to add css styles, namely inline (using the style attribute, used within a specific HTML tag), and inline (the style tag places the css code in the head part of a specific page) , External linking (use the link tag to link external css files into HTML).
1. Inline style
Use the style attribute to set CSS styles within specific HTML tags.
It is recommended not to use inline CSS because each HTML tag needs to be styled separately. If you only use inline CSS, it may become very difficult to manage the website. However, it can be useful in certain situations. For example, in situations where you don't have access to CSS files or only need to apply styles to a single element. An example of an HTML page with inline CSS is as follows:
<!DOCTYPE html>
<html>
<body style="background-color:black;">
<h1 style="color:white;padding:30px;">Hostinger Tutorials</h1>
<p style="color:white;">Something usefull here.</p>
</body>
</html>2. Inline
Inline css style is to place css code on a specific page in the
section. Inline CSS needs to be placed between the tags.Classes and IDs can be used to reference CSS code, but they are only active on that specific page. CSS styles embedded in this way are downloaded every time the page loads, which can improve loading speeds. Using inline style sheets is useful in some situations, such as sending someone a page template. It's much easier to see a preview since everything is in one page.
An example of an internal style sheet:
<head>
<style type="text/css">
p {color:white; font-size: 10px;}
.center {display: block; margin: 0 auto;}
#button-go, #button-back {border: solid 1px black;}
</style>
</head>3. External link
The external link is to use the link tag element to reference the external CSS file (.css file) to In HTML pages, references need to be placed in the
section of the page.This is the most convenient way to add CSS to html pages. This way, any changes you make to the external CSS files will be reflected on your website.
An example of an external style sheet:
<head> <link rel="stylesheet" type="text/css" href="style.css" /> </head>
And style.css contains all style rules. For example:
.xleftcol {
float: left;
width: 33%;
background:#809900;
}
.xmiddlecol {
float: left;
width: 34%;
background:#eff2df;
}Most websites today use external style sheets, which are styles that are written in separate documents and then attached to various web documents. External style sheets will affect any files they are connected to, meaning if you have a 20 page website and every page uses the same style sheet, when changes need to be made you can simply edit the style sheet to complete those pages. Makes long-term site management easier.
