CSS (ang. cascading style sheets) – is a style language that allows you to create the look of a page based on HTML or XML. CSS is one of the leading technologies used to build websites and applications. CSS, HTML and JavaScript are the 3 most important languages that Frontend developers use.
CSS styles – what’s that?
CSS style is a term that refers to the definition of styles that are applied to HTML documents using css. This means that it defines how an element should look like. With CSS styles, you can manually create a new page layout.
What HTML element can be changed with CSS?
In CSS, there are many possibilities for change. We can change, for example:
- page layout – cascading style sheets allow us to change the layout of elements on a page, their position, size, spacing,
- colour and background – enter properties for font, background or image colours,
- responsiveness of the page – CSS allows you to adjust the layout of the page to present it on different size devices, in a different orientation,
- visual effects – cascading style sheets allow you to create advanced effects, such as gradients, shadows, animations or transitions.
Font size (font size), text alignment (text-align)and background colour (background), etc. The language is constantly being developed, with new selectors and tags that are compatible with earlier versions.
How does the CSS code look like?
Example of code:
body {
background-color: white;
}
h1 {
color: red;
font-size: black;
margin-left: 20px;
text-align: center;
}How to combine CSS with HTML?
- External style sheets – CSS styles are separate files that contain in one sheet a list of declarations about the appearance of the page. Such a file is linked in the HTML file.
- Internal style sheets – style declaration is inserted inside the <style> element in the <head> section of the HTML document.
- Inline styles – the appearance is defined directly in the style attributes to the selected HTML element.
Why CSS is important for SEO?
Cascading style sheets have a very big impact on SEO. It is important for several reasons:
- Page loading speed is one of Google’s main ranking factors. By optimizing the CSS code and resources, you can improve the page’s position in the browser,
- structure and semantics – keeping HTML code clean and clear is very important. Separating CSS allows search engine robots to better understand and index the page.
- responsive site – cascading style sheets (CSS) allow you to create a responsive site that can display on different devices with different dimensions (tablet, smartphone or computer). Google places a premium on responsive sites because they provide a better user experience, regardless of the device on which the site is displayed.
