There is no such developer who does not know what a framework is. By creation of a website often used CSS, because it really saves time. The framework provides the tools needed by each web designer to create a website. I think you know that download speed is a very important factor in site quality.

For those who do not know, the framework is software that eases and accelerates the creation and combination of various elements of a serious software development.

In this article we will tell you about the top 10 CSS frameworks for creating beautiful, functional, and fast-loading websites in 2019.

#1 Pure CSS

CSS Frameworks 2019 - Pure Css

Pure is a cascading style sheet (CSS) developed by YAHOO. It helps to create fast, beautiful and responsive websites. This framework is highly optimized, it improves the comfort of working with it.

Pure CSS is one of the smallest frameworks, only 3.8 KB in gzipped format. It has a huge number of functions. Pure CSS is considered the simplest model of choice for many years, including when working with a team of software developers for outsourcing.

Pure CSS is built on Normalize.css, provides layout and style for your own HTML elements, as well as for the most common components of the user interface. This is exactly what you need for free work.

Pure CSS is a responsive framework, its elements look great while working on all screen sizes.

Pure CSS has a minimal number of styles; it allows you to create your own application styles on top of Pure CSS. It was specifically made so as not to interfere with the developer to the minimum when creating his own style.

Clean CSS requires basic knowledge of HTML, CSS, JavaScript, Document Object Model (DOM) and any text editor. A big plus will be understanding how the web applications work.

#2 Bootstrap

CSS Frameworks 2019 - Bootstrap

This framework was developed by Mark Otto and Jacob Thornton from Twitter, to ensure consistency between the internal Twitter tools. Along with Pure CSS Bootstrap is one of the most common and widely used interface systems. Using Bootstrap reduces the amount of time needed to write large codes (from ground zero). Working with such a framework significantly speeds up the process of creating pages. Standard styles are easy to change, which provides a flexible and simple process for creating site models.

HTML Resets are in a single module called “Reboot”. HTML Reset is a set of styles that replaces the usual CSS styles set in the default browser. These can be seen if the page works without CSS connected. It is accustomed to disable them so that they do not spoil the layout process.

The built-in support for flexbox provides many benefits to users. Flexbox is the most powerful component of html5, thanks to which the layout behaves exactly like a table or as a set of blocks, depending on how the developer wants. Usually, developers recompile CSS so that the block layout is not run using float: left, but based on flexbox.

The cool components of the framework are Sass variables and a more structured framework system. It is good news that the framework exists and is being improved, old mistakes are corrected and new ones arise very often.

#3 Milligram

CSS Frameworks 2019 - Milligram

Milligram provides minimal styling for a fast and clean starting point. With only 2kb in gzipped format, this tiny but powerful structure is among the top three lightweight frames.

In the Milligrams arsenal has everything you need, grids, tables, forms, tips, buttons and other tools.

The CSS Milligram introduces several new units, including the rem block, which stands for “root em”. The rem module refers to the font size of the html root element. This means that we can define one font size on the root element and define all rem units as a percentage of the total. Typography font size is 16 pixels, line height is 24 pixels. Milligram uses the Roboto font family created by Christian Robertson for Google.

A button is an essential part of any user interface. The buttons have three styles in the Milligram: the button element has a flat color by default based on color trends, whereas .button-outline has a simple outline around, and .button-clear has a completely clear outline.

The list is a very universal and common way of displaying elements in a given CSS. Milligram has three types of lists: an unordered list uses the ul element, will be marked by contour circles, an ordered list will use the ol element, and your elements will be marked by numbers, the dl element will be used in the description list, your elements will not be labeled.

There are several ways to get started. First, review all the download options available in CSS, then select the most appropriate option for your needs. Now you have to add the main Milligram and CSS Reset file to your project header. That’s all! You can work.

#4 Bulma

CSS Frameworks 2019 - Bulma CSS

Bulma has 21kB miniatures, this framework works in gzipped format. Bulma is not the easiest framework from this list, but this new structure is so interesting that it deserves mentioning. Bulma was created taking into account the mobility of the technology; this makes each element of the framework as optimized as possible for vertical reading. Its grid is fully built using Flexbox. Achieving a flexible layout with identical columns in Bulma is as easy as adding a .column class to an HTML element. The only disadvantage is that there is no JS in it.

It provides a modular sass structure for optimizing the package only for the necessary classes to be used as often as possible.

#5 UIkit

CSS Frameworks 2019 - UIkit CSS

UIkit is an easy and modular interface for fast and powerful web development.

The UIKit framework provides the necessary infrastructure for your iOS or tvOS applications. It provides window architecture for creating an author’s interface, event handling infrastructure for delivering Multi-Touch and other input types in your application, as well as a basic launch cycle necessary to manage the interaction between the user, the system, and your application. Other infrastructure features include animation support, document support, drawing and printing support, current device information, text control and display, search support, accessibility support, application extension support, and resource project management.

It is best to use the UIKit classes only from the main application thread or main send queue. This restriction applies, in particular, to classes derived from a UIResponder, or to controlling the user interface of an application.

#6 Skeleton

CSS Frameworks 2019 - Skeleton

With just 400 lines of code, Skeleton is widely spread. Despite 400 lines of code, it has a grid, typography, forms, media queries and so on, in general, everything you need to create a quality website as soon as possible.

Most often, Skeleton is used when it is necessary to create a small website project or when to create a website you do not need all the functions of large frameworks that are familiar to us. Skeleton stylizes several standard HTML elements, includes a grid, and this is often enough to start working on a website. In fact, such a site will be built on 200 lines of custom CSS (half of which will be the docking navigation). 400 lines will be used to create the site based on mobile devices. Styles in Skeleton are for the starting point, not for the user interface. You must start from scratch compiling or installing the necessary styles.

#7 Base

CSS Frameworks 2019 - Base CSS

Base is a very simple but reliable framework. Built on the principle of light and minimal code, Base was created to provide developers and designers with an easy way to create cross-browsers and mobile applications.

Base in itself is a very thin framework that requires Normalize.css and several mixins to start its work.

After completing these nuances, you can enable the features you need, such as typography, grids, individual components, and the like.

The most interesting features of the Base framework:

1. Base animation is a very thin layering, includes animation for fading in content.
2. Base buttons is a very thin layer that includes styles for decorating buttons and links.
3. Base Containers is a very thin layer that contains styles for containers.
4. Base forms contain styles for inputs, textarea, radio, flags, and other form elements.
5. Base grid contains styles for flexible grids with lines and columns for your template.
6. Base templates. Template helpers contain styles for resetting fields, layings, floats, setting different types of positions, and flexible helpers.

#8 Spectre

CSS Frameworks 2019 - Spectre

Lightweight (~ 10KB gzipped) starting point for your projects. Specter provides elegantly designed elements as well as a flexible and mobile-friendly composition.

Some advantages of Specter:

1. Beautiful elements design.
2. Huge opportunities to embody your ideas.
3. Very low weight due to the absence of JavaScript (weighs 100% less than, for example, Bootstrap), uses not much CSS (74% less than Bootstrap in gzipped format).

#9 Dead Simple Grid

CSS Frameworks 2019 - Dead Simple Grid

Dead Simple Grid is a flexible microstructure / CSS grid concept created by Vladimir Agafonkin. Often experienced programmers call this framework Malevich’s black square grid.

And now about the advantages:
1. Tiny size (about 250 bytes), no dependencies.
2. Only two classes – line and column.
3. Supports infinite data flow, allows for genuine responsive design (changing the column settings in media queries).
4. Supports all major browsers, starting with IE 8. Serves single-line mobile composition for older browsers with progressive improvements and mobile concepts.

Simple Grid is a 12-column, lightweight CSS grid. It helps to quickly create responsive websites. Download a CSS style sheet, add the appropriate classes to your layout, and you can start working. Everything is simple.

Each column is contained within the rows that are kept in the container. The container has a maximum width of 960 pixels, but you can edit it without breaking its properties.

#10 Picnic CSS

CSS Frameworks 2019 - Picnic CSS

It weighs only 3 KB in gzipped format. Picnic is undoubtedly an excellent framework that has everything you need to create a great multi-functional website, despite its weight.

There is no need to write classes that are mixed with HTML while working with Picnic. This is a huge advantage.

Picnic is completely modular, so you can easily modify it or make testing any of its parts.

You can also integrate Picnic into any project and make it work for you.

The picnic is written in SCSS with many variables and classes (fillers) to simplify its work.

In Picnic you will find a lot of thin and carefully crafted CSS switches.

Interesting fact: there is not a single line of JavaScript to control the multi-step form.

Picnic developers have set themselves a noble goal – to create highly compressed CSS (no more than 10 KB) for fast mobile download. And they did it.
