What does Cascading Style Sheets mean and what’s the types of CSS?

What is CSS?

Cascading Style Sheets is abbreviated as CSS. It is a language used to define the look and feel of websites, such as color schemes, layouts, and fonts, in order to make our websites more attractive to customers. CSS is a style sheet language for the web. It is not dependent on HTML and may be used with any XML-based markup language.

What does cascading style sheet mean?

CSS (Cascading Style Sheets) is a style sheet that allows you to separate a presentation from content, including layout, colors, and also fonts. By delivering the appropriate CSS in a separate file, this separation can improve content accessibility, provide better flexibility and control when defining presentation characteristics, and allow distinct web pages to share formatting. Cascading Style Sheet CSS file that reduces the complexity and repetition of the structural content while still allowing the. The file should be cached to improve page load efficiency across pages that use the same Cascading Style Sheets file and layout.

CSS may be created once and utilized across several HTML pages. Each HTML element has its own style, which may be applied to as many Web pages as you choose.

When you utilize Cascading Style Sheets, you don’t have to construct HTML tag attributes every time. Simply create one CSS rule for a tag and apply it to all instances of that tag. As a consequence, fewer lines of code translate to faster download speeds.

HTML attributes are now obsolete, and Cascading Style Sheets should be used instead. To make HTML pages compatible with future browsers, begin using Cascading Style Sheet CSS in all of them.

What are the types of cascading style sheets?

CSS is divided into three categories, as shown below:

Inline CSS:

Every Inline CSS style element is an HTML element. It is only used in a minor capacity. When our requirements are incredibly simple, we can use inline CSS.

It will only have an impact on one aspect. We require separate views for each HTML tag in HTML, thus we use inline Cascading Style Sheets.

There is one disadvantage to using inline Cascading Style Sheets. This information must be provided by every HTML tag. That takes a long time, and it’s not the best practice for an experienced programmer; as a result, the code will be large and complex.

Internal CSS:

The internal CSS style is given in the head> section. This is internal CSS, and also it affects all of the components in the body section. When we want to apply a style to the entire HTML body, we use internal CSS in the condition. We may do this by including the style property in the head tag.

External CSS:

We create an a.css file in External CSS and utilize it in our HTML page as needed. External Cascading Style Sheets are frequently used when we have a big number of HTML attributes that we may use as needed; there is no need to duplicate the CSS style in a full body of HTML that inherits the property of the CSS file. There are two ways to make a CSS file. The first approach is to write the CSS code in Notepad and save it as an a.css file, whereas the second is to add the style sheet directly to our Solution Explorer and instruct Visual Studio to use it on our HTML page.

CSS properties can be found in the file below. The extension of this file is .css. For instance, programming.css

The HTML file below uses the external style sheet that was produced.

• The link tag is used to link the external style sheet to the HTML webpage.
• The href property is used to provide the external style sheet file’s location.

What are the Advantages of CSS?

CSS saves time: CSS may be created once and utilized across several HTML pages. Each HTML element has its own style, which may be applied to as many Web pages as you choose.

Pages load faster: It is not necessary to add HTML tag attributes every time you apply CSS. Simply create one CSS rule for a tag and apply it to all instances of that tag. As a consequence, fewer lines of code translate to faster download speeds.

Easy maintenance: Simply modify the style to make a global change, and also all elements on all web pages will be updated instantaneously.

Superior style to HTML: Because CSS has a far bigger variety of characteristics than HTML, you can give your HTML page a much nicer appearance than HTML properties.

Multiple device compatibility: Style sheets allow material to be optimized for a variety of devices. Using the same HTML content, several versions of a website may be supplied for portable devices such as PDAs and mobile phones, as well as for printing.

Global web standards: HTML properties are now deprecated, and CSS should be used instead. It’s a good idea to start using CSS in all HTML webpages to make them compatible with future browsers.

What are the Cascading Style Sheet(CSS) Rules?

A Cascading Stylesheet (CSS) rule tells the browser how to render HTML and what to do with it. A rule can be used to determine the look of a single HTML element, or you can write your own rule that will be implemented when and when you want it.

For example, a Cascading Stylesheet rule that instructs the browser to indent the first line of every tag may be set up. You may also make your own paragraph rule and apply it to certain paragraphs instead of all of them.

There were four layout modes before the Flexbox Layout module:

• Block, for parts of a webpage Inline,
• Table, for text
• Positioned, for two-dimensional table data
• for specified location of an element

A Rule is made up of three parts: the Selector, the Property, and the Value.

The Selector:

CSS selectors are classified into three types: HTML selectors, Class selectors, and ID selectors.

An HTML Selector is the text component of an HTML tag. The whole paragraph tag is P>. So the HTML Selector is just P’removing the angle brackets yields the HTML Selector.

A Class Selector is a feature that you can add to your page and use wherever you want. In our last STYLE example, Font1 was a Class Selector. We created the nickname and utilized it to construct some text for the website. An ID Selector, like a Class Selector, is used to identify a specific element, such as a text box on a form.

In a STYLE tag, here’s an example of how all three selectors appear.

(insert picture)

The first one is the HTML Selector, H1. It should be noted that the angle brackets have been removed. When you use an HTML selector, all HTML tags on the page will be formatted in the manner you specify. As a result, all information on the page between the H1>/H1> tags for H1 above will now be in Red.

The second option is the Class selection.

NewFont. It is critical to remember that a class selector must begin with a full stop (period). Then you name your selector (anything you want). There is no space between the full stop and the name of your choice.

The final ID option is #NewTextboxColour. An ID selector is initiated by the hash/pound (#) symbol. Then you type in the name of the ID selector that you want to utilize. Once again, there is no space between the symbol and the name of your choice.

Property and Value:

You’ll need to define your Selector’s Properties and Values after you’ve built it.

The item you want to change is the selector’s Property. Some examples include font, color, background, margin, and text.

The selector’s Value represents the new setting for the property. For example, we may use the COLOR property to provide a specific color (red, blue, or yellow) or a color code (#FFFF00, #000000).

Both the property and the value are surrounded by curly brackets. The syntax for the entire thing would be as follows:

Property: Value Selector

An example is:

H1 {Color: Red}

The selector is H1, the property is Color, and the value of the property is Red. After the Property, there is a colon (: ). This is used to distinguish between a Property and a Value so that the browser can tell which is.

There are two ways to add more than one property and value: all on one line, with each pair of properties and values separated by a semi-colon; or all on two lines, with each pair of properties and values separated by a semi-colon ( ; ). Alternatively, each pair of attributes and values can be separated by a semi-colon on several lines ( ; ). As an example:

H1 {Color: Red; Font-weight: Bold; Font-Size: 16pt;}

This is the multiple-line version:

To summarise, a cascading style sheet CSS rule has three parts: a Selector, a Property, and a Value. The Selector can be an HTML selector, a Class selector, or an ID selector. Curly brackets are used to divide the Property and Value from the Selector, with the left curly bracket coming first and the right curly bracket concluding the rule ( : )

What are the versions of CSS?

CSS1:

CSS1 (Cascading Style Sheets, Level 1) was proposed by the World Wide Web Consortium (W3C) in December 1996. This version provides a rudimentary visual formatting model for all HTML tags, as well as a CSS language definition.

CSS2:

CSS2 is a W3C recommendation that was released in May 1998 and is an improvement to CSS1. This version includes support for media-specific style sheets, such as printers and audio devices, as well as downloaded fonts, element positioning, and tables.

CSS3:

CSS3 was released in June 1999 as a W3C recommendation, and it is based on prior CSS versions. It has been divided into documentation modules, with each module including new extension capabilities documented in CSS2.

CSS3 is the most recent version of the CSS standard for cascading style sheets (CSS2). The following are the primary distinctions between CSS2 and CSS3:

• Media Queries
• Namespaces
• Selectors Level 3
• Color
