Chances are you’ve heard of HTML, even if you don’t know what it stands for. But are you familiar with CSS? CSS is widely used by software engineers, so if you’re interested in pursuing a career in the tech industry, then you should consider learning some basics.
Cascading Style Sheets (CSS) is a front-end programming language focused on simplifying the process of making web pages presentable.
Web developers use CSS to manage the visual aesthetics of a web page. CSS allows you to change the color of the text, font style, spacing between paragraphs, column size and layout, background images and colors, layout designs, device screen adaptability, and other similar effects.
CSS is not only simple to understand and easy to learn, but also offers more control of an HTML document presentation. CSS is quite often combined with markup languages such as HTML or XHTML.
Introduction To CSS
It is designed to allow the segregation of presentation and content, such as layout, colors, and fonts. This separation of the two entities can help in improving various aspects, such as content accessibility, presentation characteristics, multiple web pages formatting, and complexity of the structural content. Thus, the emphasis of CSS is placed on ‘style’.
While HTML helps in structuring an internet document, CSS handles the task of specifying your document’s style. That means HTML allows functions such as defining headlines and paragraphs, embedding images, video, and other media. On the other hand, CSS helps you specify your document’s page layouts, colors, and fonts.
To better compare, think of HTML as the frame of a car and CSS as the bodywork. You can combine them in multiple ways to create unique vehicles, but a sedan can’t be the same as a truck!
How Does CSS Work?
First, you need to understand what a ‘document’ is. A document is normally any text file that has been structured using a mark-up language like HTML, SVG, or XML. To present a readable document to a user, it requires converting the document into a form that is easily understandable by the user.
Now, it is important to note that CSS can be used for basic document text styling. For instance, it can be used to change the color and size of headings and links; or to turn a single column of text into a layout. Also, CSS can even be used for visual effects such as animation.
In CSS, you can define the rules specifying groups of styles that you want to apply on your webpage. For instance, let’s assume that you want the main heading of your webpage to be shown as large black text. To achieve that, a simple CSS rule can be applied as shown in the following code:
font-size: 10 em;
In the above code, the rule opens with a selector. The purpose of this selector is to select the HTML element that you are going to style. Here, you are going to style level one headings, therefore we use <h1>.
Next, we have a set of curly brackets that consists of one or more declarations. These are in the form of property and value pairs. First, these pairs assign a property to the selected elements, and then a value you want to assign to that property.
Then, you can notice the property mentioned before the colon, and the value of the property after the colon. The properties in CSS have different permissible values, depending on which property is being specified.
Therefore, you will find that a CSS stylesheet consists of multiple rules like this, often written sequentially. If you choose to learn CSS, you will realize that although you may learn some of these values quickly, others may require some time.
Role Of CSS In Web Development
To become a successful front-end developer, you must have a deep understanding of both HTML and CSS. The first skill to learn in web development is HTML. HTML is essentially a standard mark-up language, and its knowledge will allow you to create stylish and attractive web pages. The best part of HTML is that it’s easy to learn and understand. It has been used for decades now in web development and is particularly significant in front-end development.
However, once you’ve understood how to design using HTML, you’ll want to take your skills a step further--that’s where CSS comes in. CSS allows you to uplevel your designs and truly bring a website to life. CSS lets you add colors, background images, and other visual features to your website. With that being said, when you learn CSS your design skills will really begin to shine.
As you can see, you’ll want to know both HTML and CSS to thrive as a front-end developer.
How Hard Is It To Learn CSS?
By studying others’ code, anyone can learn the basics of CSS. The key, however, is not just to read it, but to also break it down until you understand it. Once you put the effort in to study CSS, you’ll soon realize that it’s not as intimidating as it may seem at first.
CSS is vast and there are diverse, interesting applications of it. It can be said that CSS is easy to learn, however, mastering it is a bit of a task. While making a simple website can be learned quickly, becoming fluent in CSS usually takes much longer.
Learning this styling language requires dedication and determination. Although learning any new language is a demanding experience, many CSS learners describe the process as one which gradually gets tougher. Some reasons why developers consider CSS as hard to learn are:
•Because of its high level of technicality, CSS isn’t the easiest language to understand.
•CSS has been developed as a full-fledged programming environment for web applications, and web applications also require a user interface, making it more complex.
•The paradigms associated with CSS are not considered very user-friendly.
How To Learn CSS
There’s a plethora of online resources out there to help you learn to code. And while you can teach yourself CSS, you’ll need to invest in an online web development course if you want to learn the full scope of technical abilities and soft skills that lead to a long-term engineering career.
Your first step should be to identify what type of learner you are to choose a course that suits you best. For many career-changers, the freedom of taking an online course offers a major advantage over traditional in-person classes.
