CSS 3 vs Less: What are the differences?

## Introduction

Key differences between CSS 3 and Less are outlined below.

1. **Preprocessor Capabilities**: Less is a preprocessor language that extends CSS with dynamic behavior such as variables, mixins, functions, and nesting, which CSS 3 lacks. This allows for more efficient and reusable code in Less compared to traditional CSS.
2. **File Extension**: CSS files have a ".css" extension while Less files have a ".less" extension. Less files need to be compiled into CSS files before being used on a website, whereas CSS files can be used directly.
3. **Mathematical Operations**: Less allows for mathematical operations in stylesheets, enabling developers to perform calculations like addition, subtraction, multiplication, and division directly in the stylesheet. CSS 3 does not support such operations, requiring developers to hardcode calculated values.
4. **Importing Stylesheets**: Less allows for importing external stylesheets into a main stylesheet, making it easier to manage and organize styles. CSS 3 does not have native support for importing stylesheets, leading to larger and more complex stylesheets.
5. **Browser Compatibility**: CSS 3 is supported by most modern browsers, while Less is not natively supported and requires compilation to standard CSS for browser compatibility. This extra step may impact the development process and performance.
6. **Development Environment**: Less requires a specific compiler to convert Less code into standard CSS, while CSS 3 can be written directly in any text editor without the need for compilation. This additional step in the development process can increase the complexity of the workflow for Less.

In Summary, CSS 3 and Less differ in terms of preprocessor capabilities, file extensions, mathematical operations, importing stylesheets, browser compatibility, and development environment.

7 Awesome CSS3 Techniques You Should give a Try

  1. Vertically Align With Flexbox Earlier developers used to face a lot of difficulties aligning a text or any other element vertically center. But now, after the introduction of the new CSS3 specification Flexbox, things have become much easier.

  2. Responsive CSS Grid Do not make your grid an exception make it responsive too, like everything else in your design.

There are so many ways through which you can make your grid responsive with CSS Grid. And the best part of using it is, you will be able to create a more flexible grid that gives you the desired look, no matter what the device size is.

  1. Text Animations You might have created background animations with CSS, but now it also influences how users interact and engage with the text elements of a website. From hover adjustments to making words float in the air, CCS3 has made it all possible.

  2. Columns layout Usually, column-based layouts are created by using Javascript, which is quite complicated and time-consuming. But CSS has brought a way around to ease up the task of developers and web designers.

  3. Screen Orientation Many people think that screen orientation and device orientation both work for the same purpose. But that’s not the case. The orientation of the screen is a bit different from the device.

Even if a device is not capable of detecting its orientation, a screen always can. And if the device is capable also, then it’s good to have control over the screen orientation so that you can maintain or change the interface of your website.

  1. Comma Separated Lists There is no doubt that Bullet lists are very commonly used in writing to convey any information more precisely and clearly. But one thing that most people struggle with is to add commas on every point of the lists.

  2. Animated Checkbox Well, most of the people are very much aware of the CSS background and text animations. But, not many know about checkbox animations.

Yes, apart from background and texts, you can also make your checkbox section look visually appealing. Isn’t it great?

This post is a bit of an obvious one, as we have a web application, we obviously need to have HTML and CSS in our stack. Though specifically though, we can talk a bit about backward compatibility and the specific approaches we want to enforce in our codebase.

HTML : Not much explanation here, you have to interact with HTML for a web app. We will stick to the latest standard: HTML 5.

CSS: Again if we want to style any of our components within he web, we have to use to style it. Though we will be taking advantage of JSS in our code base and try to minimize the # of CSS stylesheets and include all our styling within the components themselves. This leaves the codebase much cleaner and makes it easier to find styles!

Babel: We understand that not every browser is able to support the cool new features of the latest node/JS features (such as redue, filter, etc) seen in ES6. We will make sure to have the correct Babel configuration o make our application backward compatible.

Material UI (MUI): We need to make our user interface as intuitive and pretty as possible within his MVP, and the UI framework used by Google will provide us with exactly that. MUI provides pretty much all the UI components you would need and allows heavy customization as well. Its vast # of demos will allow us to add components quickly and not get too hung up on making UI components.

We will be using the latest version of create-react-app which bundles most of the above along many necessary frameworks (e.g. Jest for testing) to get started quickly.

For our front-end, React is chosen because it is easy to develop with due to its reusable components and state functions, in addition to a lot of community support. Because React is popular, it would be easy to hire for it here at our company MusiCore. Our team also has experience with React already. React can be written with ES6 and ES6 has a lot of popularity and versatility when it comes to creating classes and efficient functions. Node.js will be used as a runtime environment to compile the code. Node.js also has many different types of open-source packages that can help automate some of the tasks we want to do for the application. CSS 3 will be used to style components and is the standard for that.

    What is CSS 3?

    CSS3 is the latest evolution of the Cascading Style Sheets language and aims at extending CSS2.1. It brings a lot of long-awaited novelties, like rounded corners, shadows, gradients, transitions or animations, as well as new layouts like multi-columns, flexible box or grid layouts. Experimental parts are vendor-prefixed and should either be avoided in production environments, or used with extreme caution as both their syntax and semantics can change in the future.

    What is Less?

    Less is a CSS pre-processor, meaning that it extends the CSS language, adding features that allow variables, mixins, functions and many other techniques that allow you to make CSS that is more maintainable, themable and extendable.
