The CSS font-size property defines the text size to be used. Undoubtedly, CSS does have a strong community of support as well as backup to ensure improvements in the web designing on an ongoing process. CSS style definitions are saved in external CSS files so it is possible to change the entire website by changing just one file. CSS is used along with HTML and JavaScript in most websites to create user interfaces for web applications and user interfaces for many mobile applications. I recently started a weekly coding challenge series aimed at teaching beginners how to program in JavaScript. I really hope you got something useful from this article.

It’s a powerful tool for creating responsive and visually stunning websites that adapt to various devices and screen sizes. The history of CSS is a testament to the evolution of the web, from its text-based origins to the visually dynamic digital landscape we experience today. CSS3 Selectors introduced powerful techniques for precisely targeting and styling elements in web development, enhancing the flexibility of web design. In the ever-evolving world of web development and design, cascading style sheets, or CSS, have played a pivotal role in shaping the aesthetics and functionality of websites.


The rules that govern this process are called CSS selectors. CSS is easy to learn and understand, but it provides powerful control over the presentation of an HTML document. CSS (Cascading Style Sheets) is a stylesheet language used to design the webpage to make it attractive.

It can be used to create a layout — for example, turning a single column of text into a layout with a main content area and a sidebar for related information. what does css do for a web page Have a look at the links in this paragraph for specific examples. HTML is basically the standard markup language for describing the structure of web pages.

CSS Responsive

CSS is a rule-based language — you define the rules by specifying groups of styles that should be applied to particular elements or groups of elements on your web page. A document is usually a text file structured using a markup language — HTML is the most common markup language, but you may also come across other markup languages such as SVG or XML. HTML relies on tags for structuring content and other elements of the web page. In contrast, CSS uses only selectors to declare block statement syntax.

This means that the code has been written to turn the instruction in our CSS file into something that can be output to the screen. We’ll look at this process more in the lesson How CSS works. It is unusual for all browsers to implement a feature at the same time, and so there is usually a gap where you can use some part of CSS in some browsers and not in others. For this reason, being able to check implementation status is useful. You will find that you quickly learn some values, whereas others you will need to look up. The individual property pages on MDN give you a quick way to look up properties and their values when you forget or when you want to know what else you can use as a value.

In some instances a raster image can be used successfully when working with logos, especially if there the logo is more image rather than text based. It is recommended, though, to create the logo as a vector file and save copies as raster images as needed for specific projects. Type and fonts are also created as vector images, which allows you to change the size while maintaining quality. This also keeps type from looking blocky and helps certain typefaces maintain their smooth shapes and edging.

They are ideal for use when an image will only be used once, and will never need to be enlarged, or if portions are coming from a photograph or other real-world image. The word “raster” has its origins in the Latin rastrum (a rake), which is derived from radere (to scrape). The word rastrum is now used to refer to a device for drawing musical staff lines.

Vector Image Applications

Vector graphics produce and save the file as a series of vector statements. Instead of creating a bit in the file for every line segment, we use instructions that raster and vector graphics difference provide a list of points that need to be connected. Read this blog to know the difference between raster and vector graphics & other related information.

Many raster manipulations map directly onto the mathematical formalisms of linear algebra, where mathematical objects of matrix structure are of central concern. Vector images also have the tendency to stand out with their attractive use of color, texture, depth, and layers. This gives businesses another reason to use them in their promotional content. This material can include everything from billboards to posters and business cards. Hence, they need to make sure their illustrations are scalable and can be enlarged or reduced in size as needed.

The Difference Between Vector Graphics and Raster Graphics

If you don’t want to spend money, you can take a look at any number of the best free Adobe Illustrator vector alternatives available online right now. Among free options, Inkscape and Vecteezy are very popular programs, and both feature a lot of robust tools to make your best vectors come to life. Vectors’ scalability make them ideal for design work consisting of logos and icons. Both logos and icons require immense details and many size options, usually depending on their application.

  • Raster the program uses adobe photoshop and GIMP and one can use this program in designing and developing websites, app design, icon design, banner design, advertisements design, and other purposes.
  • Higher DPI (dots per inch) and PPI (pixels per inch) settings also contribute to larger files because software must keep track of and be able to render each pixel.
  • In other words, if you want the same image to appear at different sizes, you would need multiple raster images as opposed to just a single vector.
  • So we can conclude there are different purposes for using both raster and vector images.
