The primary distinction between external CSS and inline CSS is the processing speed; using inline CSS only needs the browser to download one file, whereas using external CSS necessitates downloading both HTML and CSS files.
Cascading Style Sheets
Cascading Style Sheets‘ primary objective is to distinguish between the content of a document and its presentation, which includes style components like colour, layout, and fonts.
The design and aesthetics of an internet website are handled by CSS. You can modify the text’s colour, font style, paragraph space, column size and layout, among other things, by using CSS.
Devices can easily read CSS updates. There is a need for responsive website design because consumers use a wide variety of smart devices to visit websites online.
It is capable of shifting positions and assists us in figuring out how the positions of the web elements that are present on the page have changed.
What is External CSS?
You often use the external style sheet when you need to make changes to several pages. It is perfect in this situation because it enables you to alter just one file to alter the appearance of the complete website. Every page uses the <link> element, which needs to be placed within the head section.
The following benefits of external style sheets over inline and internal styles:
- You may develop style classes that can be applied to numerous different HTML elements.
- Uniform appearance and experience across many web pages
- All connected pages will be affected by a modification to the style sheet.
- Faster load speeds because each relevant page just needs to have the CSS file downloaded first and applied as necessary
- External CSS helps avoid extraneous information and makes HTML files tidy and small.
- You may organise the styles with it. As an illustration, the styles for one area of a website may be preserved in a different file, and those for the other section(s) could be kept in a different file.
- It makes navigation simple. You don’t scroll down your lengthy HTML file when you need to find the style of a specific element. Instead, you know where to look for it in the CSS file.
Linking External CSS to HTML
The two most important languages for web development are HTML (Hyper Text Markup Language) and Cascading Style Sheets. While CSS determines the look and layout of a website, HTML defines its content and organisational structure. Together, the two languages make it possible to build a well-organised, useful website.
Although there are several ways to link CSS to an HTML file, linking external CSS to an HTML document is the most effective method. It necessitates the creation of a new document with the.css extension that only contains CSS rules and no HTML tags.
In contrast to inline and internal styles, such a technique modifies numerous HTML pages by altering a single CSS file. It saves time because it is unnecessary to modify every CSS property on every website’s HTML page.
To link an external CSS to HTML, follow the below steps:
- Create an external CSS document with the help of an HTML text editor and implement CSS rules to begin linking style sheets to HTML files.
- By including a ‘link’ element within the head element of an HTML file, you may link any CSS file to an HTML file. The ‘link’ element can be used for a variety of purposes. Thus it’s crucial to give the correct characteristics to utilise it to import an external CSS stylesheet.
- The ‘rel’ attribute is the initial of the two necessary qualities. This attribute will be used to inform the browser of the relationship to the imported file. To inform the browsers that you are going to import a stylesheet, you will put rel=”stylesheet”.
- The ‘href’ attribute, which designates the file to import, is the second crucial attribute.
The CSS file and the HTML file are frequently found within the same folder. You may then use href=”style.css” in this situation.
You must specify the right path from the HTML document to the CSS file if the CSS document and HTML file are located in different directories.
How to Include External Font Files in CSS
Below is a step-by-step tutorial on how to use and import .ttf (true type fonts) into HTML using CSS.
- The.ttf format is relatively well-known, and Google offers these font files without charge. Websites like font space and others offer these fonts without charge. It is advised to keep each file in its folder.
- Make an HTML file and insert an H2 tag to show the font style.
- The @font-face attribute element is used to specify the font name and source file manually when adding external fonts via CSS. After that, we can use the Font-family attribute to obtain the defined font in just about any element that needs it.
- The final result will be exhibited, and the font of your choice or an external font file will be added.
External style sheets have the distinct advantage of being able to be produced in any text editor and saved with the.css extension. There shouldn’t ever be any HTML components in the file.
In an HTML document, there are two primary methods for invoking an external style sheet. Utilising the element in the Html content head is one approach. Another approach involves using both embedded and external CSS functions together.
The use of external style sheets has advantages. There is no restriction to the number of web pages that can use the external style sheet.
The look can be instantly applied to every single web page using an external style sheet. They can also assist in giving each page to which they have linked a consistent format.
We must remember that with CSS, some functions in one browser may not always function in another. The application must be tested for compatibility by web developers using a variety of browsers.
