Advantages of Using CSS Framework

Broadly speaking, you must have caught on to the main advantages of using a CSS framework. But so that you are more confident in determining whether a CSS framework is really needed or not, we will tell you what its advantages and disadvantages are.

Below, we will first explain in terms of the advantages of using the CSS framework, namely:

1. Easy for Beginners

CSS framework is the right choice for those of you who are beginners. Simply by mastering basic HTML and CSS, you can create a good front-end with the help of a framework.

Apart from providing many supporting features, each framework also has detailed guides and documentation. So, you can just follow it and make the design as you wish.

2. Ready-made Elements

One of the challenges for front-end developers is to put every UI element together. Starting from the buttons, navigation, typography and so on. This is done so that the UI elements can function optimally and not be difficult for your users.

Of course, it will take a lot of time if you build everything from scratch. But with the CSS framework, the process can be completed in a shorter time.

Within each framework, various ready-to-use element styles are available. The rest, you just focus on the ‘creative’ side of your project. For example, think about the layout, grid, and so on.

3. Have a Grid System

Grid is a structure in the form of horizontal lines, vertical lines, or diagonal lines. These lines form columns with the same spacing and width. Grid functions to make it easier for you to arrange each UI element in the layout so that it is neat and structured.

4. Produce Stable Performance

Almost every CSS framework is open-source, so anyone can get involved in developing the framework itself. Even so, each CSS framework also has a very strong community.

This is good news for you. Because apart from being able to use the CSS framework for free, you can ensure that every code designed will be minimal from issues such as typo or error code .

That way, the quality of the performance of your website and applications can be guaranteed to be stable and work responsively.

Disadvantages of CSS Framework

After you recognize the various advantages of using a CSS framework, next we will explain what are the disadvantages.

1. It’s Hard to Develop Your Own Design

Each CSS framework has a specific code standard or grid system. This has resulted in some frameworks limiting you from designing the design as you wish. For example, changing the layout size, grid width, button model, and others.

In addition, you will tend to be stuck with the same framework model. You can’t make quick changes to some of the code.

Even if you want to make a lot of modifications, the time you will spend is not small. Especially if your project requires parameters or design standards that must be unique or unconventional.

2. Lots of Unimportant Codes

In order to meet the needs of users, each framework also provides a large selection of variables, features, and elements. However, sometimes there is also a lot of code structure or script that is not needed.

If you’re skilled enough, you might be able to easily remove unnecessary lines of code. However, if you are still learning, it will be a hassle. It’s possible that you deleted the wrong code.

Instead of producing optimal performance, your front-end becomes a mess.

3. Mainstream Design Structure

If you want to structure your front-end design other than the other , most likely you will have trouble finding the right framework.

As we explained earlier, each framework has been designed with a certain style and code. If you want to make a lot of code changes, it will take quite a bit of time.

So the risk is when you use the framework, there will most likely be other users who have a similar appearance to your website or application. Unless you’re an expert, it might be easier to do a lot of code modifications.

Tips for Determining the Right CSS Framework

Here are some tips to help you determine the right framework:

1. Adjust to the Website or Application Design Concept

You must first identify what kind of website or application you are going to create. Do you want a complex design concept? Or simple?

Well, here are recommendations for CSS frameworks based on each type of your website or application.

Type of Website / Application CSS Framework
Minimalist website / application. UIKitMilligramPureCSS
Website / application for enterprise. BulmaBootstrap Foundation
HTML email Foundation

2. Define the Framework Programming Language

You should also know what programming language you want to use when using the CSS framework. According to our explanation earlier, there are several frameworks that only use standard programming languages ​​such as HTML. On the other hand, there are also frameworks that use more complex programming languages ​​such as CSS and JavaScripts.

Not infrequently also some of them have SASS and LESS support to unify every UI element. In essence, adjust to your programming language skills. If not, you will find it difficult to use the framework itself.

3. Choose a CSS Framework that Provides Various Features

Of the many features offered in each framework, at least make sure the framework has the following features:

  • Responsive design. This is important, because it will concern the user’s convenience when visiting your website / application.
  • Mobile friendly. Choose a framework that is able to produce optimal website / application quality on any device, especially mobile.
  • Browser support. Use a framework that works responsively across all browsers.

4. Make sure the CSS framework is customizable

Although the function of the CSS framework is to avoid creating code from scratch, it doesn’t mean that the code can’t be changed or customized. Customizable frameworks will give you room to be creative.

At a minimum, you can have a front-end that matches the character of your brand. Or avoid looking similar to other users’s. However, do not also choose a framework that requires you to do a lot of customization. It will be just like you coding from scratch.
