<p class="ql-align-justify">CSS stands for&nbsp;<strong>Cascading Style Sheet</strong>. Where&nbsp;<em>HTML</em>&nbsp;is what defines the&nbsp;<em>structure</em>&nbsp;and&nbsp;<em>content</em>&nbsp;of a web page, a&nbsp;<em>Cascading Style Sheet</em>&nbsp;is a web document that allows you to change the&nbsp;<em>appearance</em>&nbsp;of the HTML.CSS allows you to change the size, style, font, and color of text; margins and padding; background colors and border styles. It can also be used to position elements on a page.</p><p class="ql-align-justify"><br></p><h2>Applications of CSS</h2><ul><li class="ql-align-justify">CSS saves time&nbsp;- You can write CSS once and then reuse same sheet in multiple HTML pages. You can define a style for each HTML element and apply it to as many Web pages as you want.</li><li class="ql-align-justify">Pages load faster&nbsp;- If you are using CSS, you do not need to write HTML tag attributes every time. Just write one CSS rule of a tag and apply it to all the occurrences of that tag. So less code means faster download times.</li><li class="ql-align-justify">Easy maintenance&nbsp;- To make a global change, simply change the style, and all elements in all the web pages will be updated automatically.</li><li class="ql-align-justify">Superior styles to HTML&nbsp;- CSS has a much wider array of attributes than HTML, so you can give a far better look to your HTML page in comparison to HTML attributes.</li><li class="ql-align-justify">Multiple Device Compatibility&nbsp;- Style sheets allow content to be optimized for more than one type of device. By using the same HTML document, different versions of a website can be presented for handheld devices such as PDAs and cell phones or for printing.</li><li class="ql-align-justify">Global web standards&nbsp;- Now HTML attributes are being deprecated and it is being recommended to use CSS. So its a good idea to start using CSS in all the HTML pages to make them compatible to future browsers.</li></ul><p class="ql-align-justify"><br></p><p>CSS frameworks are an extremely popular front-end development tool. They can allow developers without vast CSS and JavaScript experience to create beautiful, interactive websites. However, when deciding to use a CSS framework for the first time, it is easy to become overwhelmed by the number of options out there. This article will provide an introduction to CSS frameworks in general, as well as a few of the most popular options available.</p><p><br></p><h2>What is a CSS Framework?</h2><p>A CSS framework is a combination of design best-practices and standardized class systems that provide a basic structure for styling a web page. Practically, they are usually an external stylesheet that you link to, giving you a grid system to layout content and a collection of CSS classes to style elements with. Often, frameworks will also provide whole components, which are chunks of HTML that come pre-styled with CSS. These can range from simple buttons to entire forms or navigation bars. Some frameworks also come with font and icon libraries, as well as JavaScript files for animations and interactivity.</p><p><br></p><h2>Most Popular Frameworks</h2><h2>Bootstrap</h2><p>Originally developed at Twitter to create consistency among internal projects,&nbsp;<a href="https://getbootstrap.com/" rel="noopener noreferrer" target="_blank" style="color: rgb(41, 98, 255);">Bootstrap&nbsp;</a>has grown to become one of the most popular CSS frameworks, often being the default choice for many developers. It offers a wide variety of page templates and UI components (chunks of HTML you can add to your code) and tons of styling options for everything. Bootstrap also offers templates that include JavaScript for interactivity and animations. While it’s relatively simple to get started on, the massive amount of options can make it easy to get lost in as a beginner. Bootstrap has also become so ubiquitous that some developers worry websites styled with it won’t stand out.</p><p><br></p><h2>Bulma</h2><p><a href="https://bulma.io/" rel="noopener noreferrer" target="_blank" style="color: rgb(41, 98, 255);">Bulma&nbsp;</a>is an lightweight CSS-only framework. Bulma is extremely beginner-friendly, with intuitive class names and easy-to-follow startup tutorial. I also think Bulma is one of the most beautiful CSS frameworks straight out of the box, with a clean and colorful aesthetic. Additionally, the community is very passionate, so you can find a lot of helpful guides and code snippets to guide you along the way. Since Bulma is CSS only, you will need to provide your own JavaScript if needed.</p><p><br></p><h2>Tailwind CSS</h2><p><a href="https://tailwindcss.com/" rel="noopener noreferrer" target="_blank" style="color: rgb(41, 98, 255);">Tailwind CSS&nbsp;</a>is a little bit different than other frameworks, because it doesn’t focus so much on delivering ready to use components, but it’s more about utility classes, which help developers to build what they need. It’s more like giving ready building blocks for components.</p><p>Sometimes it may look ugly while we add too many classes, but the goal is reached. Although it’s not a primary goal of the Tailwind CSS framework, the elements have a pretty beautiful design.</p><p><br></p><h2>Foundation</h2><p><a href="https://get.foundation/" rel="noopener noreferrer" target="_blank" style="color: rgb(41, 98, 255);">Foundation</a>&nbsp;is an industrial-grade CSS framework favored by large companies such as eBay, Disney, and Mozilla. While some think it isn’t as aesthetically pleasing as Bootstrap out of the box, it is one of the most powerful frameworks available. This is because it takes a minimalist approach to style pre-built components, allowing designers more room to customize the final product. Foundation is the most complex framework on this list, and I wouldn’t recommend it for beginners.</p><p><br></p><h2>Semantic UI</h2><p>Semantic UI is another competitor, among other CSS frameworks. It grew with the unique approach they have, focusing on human-friendly HTML, and exactly that’s the feeling I got using Semantic UI.</p><p>The human-friendly HTML approach made Semantic UI an easy to learn framework which is easily accessible even for beginners. While using Semantic UI, the image has simple the "ui image" class, and if you want to change the size, nothing complicated. It’s enough to add a "small" class.</p><p><br></p><h2>Materialize</h2><p><a href="https://materializecss.com/" rel="noopener noreferrer" target="_blank" style="color: rgb(41, 98, 255);">Materialize CSS</a>&nbsp;is built on Google’s Material design principles. Material is one of the most popular design languages, with most of Google’s applications, including YouTube and Google Drive, being built on its principles. If you are going for the look and feel of google and android, this is likely the framework for you.</p>
