It’s 2020 and you want to learn how to create beautiful and modern websites in 2020? This Article will serve as a guide on what you should be looking into, in order to learn to build fast and beautiful websites. We’ll also mention some keyword for technologies with potential, which you can look into.
What is a Website in 2020?
A question that simple shouldn’t be asked in 2020, right? But the lines between Apps, Websites and Software is fading. Here is a good example: certain websites you visit on the phone, you can ‘add to homescreen’. This adds an icon of the website and makes it available even when you offline. (Here is good starting point if you want to learn more about this technology: Progressive Web Apps).
So what is it now? An App or a website? How can you access a website that is offline?
For the sake of simplicity we’ll say that everything is accessed via a browser, is a website. (Except for PDF files, Video files, etc.)
What was Webdesign?
Certain plugins go even a step further and give you finished and multi-functional User Interface Elements (for example a Button). You can read more on such frameworks here: Top 3 UI Frameworks.
So, where you start?
If you are starting your developer journey in 2020, you should feel blessed. You’ll receive advanced programming language and tons and tons of tutorials and cheap (but not always good) courses. Following lines assume that you want to know how to become a Frontend developer.
We’ll also assume that you don’t want to become a Frontend developer just for the sake of becoming of Frontend developer. The motivation behind this is mainly to earn money. Then comes fun and enjoyment. We do not distinguish whether you make money via a wage or freelance work.
In the end it all comes down to fulfilling the demand (for in Frontend development) with your supply of this skill.
Web Dev Basics
Every Website on the these two most basic technologies: HTML5 and CSS.
HTML5 equals to Hyper Text Markup Language 5. It’s the standard markup language for virtually every Website. HTML elements are the most basic elements of an HTML page.
CSSequals to Cascading Style Sheets. CSS takes the UI Elements that were created by HTML and adds some style to them – making our website beautiful and modern.
Modern Websites for Beginners
How to learn it? Well, some people prefer skimming through the docs and learn via trial&error. Others prefer a more focused and directed learning with Courses.

We at German IT Academy are very eager to see first official release of the third Version of Vue.js 3. Therefore we are watching the developments closely and will be publishing many Posts, Tutorials & Courses on Vue.js 3. It does pay off to be on our Newsletter list (scroll down to subscribe) or check this Vue.js 3 Guide once i a while.
Also, check out the first “awesome-vue3″ repository with an updated and curated list of all resources regarding Vue.js 3.
Currently the vuejs team is working on three projects: the 2.7 Version, Maintenance of current codebase and the Roadmap (mainly the third version of Vue.js).
Major Changes in Vue.js 3
Let’s explore the official plans for third Version of Vue.js. We will also derive a great lot of content from the vue/rfcs, where all the RFCs are developed and discussed (Note: RFC = Request For Comment). We picked some of the most interesting ones and included a basic code example. As the changes become more certain, we will update our Vue.js 3 Guide to have more detailed examples.
Official RFCs December 2019
There is a long explanation of what the Composition API is. Generally, the motivation behind it is the reuse of Logic, better Code Structure and better Type Inference. Here is a basic Example:
Before we start with another VueJS Tutorial, let me promote our VueJS Course with a Certificate right at the beginning. You’ll see more interactive and deeper Content about VueJS. At the end you’ll also receive a VueJS Certificate from German IT Academy. That’s it.
Problem / Task
While coding a solution for the following tasks, make sure to make use of every single v-directive at least once: v-text, v-html, v-once and v-model. Also, do not forget to use conditional and iterative v-directives, if needed.
In CustomizeDonut, create 4-step input process, in which a user has to perform one data-selection in each step. Use v-model as much as you can. The steps should have individual h1 titles and individual Button Values.
Select Donut by name (see Sample Data)
Select Batter Type
Select Topping Type
Last step: Show the summary and a dummy button “Order Donut”
Here is a sample Object of a Donut. Few things stand out: We have a type and a name. We have a list of “batters” and “topping”, which contain object with further details.
To have a multi-step process, you have to track the status of the current process. You can do it with an object. Or simpler yet, a variable that will store the step number that the user is currently performing.
Here is the solution we came up with for this VueJS Tutorial. Please that is no definite solution, except that the v-directive are used correctly. We smashed the solution into one Vue Component, that way we make it simpler to understand by not having the code in 3-4 different files.
Here is quite a lot happening, let’s go trough it.
First we have created a very simple step process by having a step data property and showing conditional HTML content based on that property; we achieve this with v-if and v-else-if v-directives.
Our data property stepConfig tells our App what title, what button text and what the button-action should be. Notice that we use a function for stepConfig.nextStep; this is because we use the v-directive v-on on our button. This directive needs a function as a parameter. @click=”stepConfig[step].nextStep”
Our computed properties help us extract or filter the correct batters and topping for the donut selected by the user.
In order to store user Input we created an object userInput and we mapped the keys “userInput.donutId”, “userInput.batterId” and “userInput.toppingId” with v-model to the select.options HTML Tags. This way our App has always the most recent user input saved in this Object.

Here is a visual version of our solution. Please note, we know VueJS, but we suck at Design.
Welcome to another VueJS Tutorial. Let’s explore a very important topic in VueJS: the relationship between your Vue-Components. It’s crucial because everything is importing everything from everywhere anytime…or something like this.
For those who are new to VueJS Tutorial / VueJS Practice: we create a fictional problem / task for you to solve. To go through it and try and code a solution that would solve the issue. Then you compare it with the solution provided by German IT Academy.
Problem / Task
create DataSourceList.vue that reads from state ‘datasources’ in vuex store.
For every Entry in the ‘datasources’ list, embed a a DataSourceItem.vue in the DataSourceList.vue.
DataSourceItem Component receives the props ‘id’ from the Parent. With that id the Child fetches all the data from ‘datasources’ in vuex store and displays them.
DataSourceItem Component receives a slot from the Parent and displays the content in a random place.
When importing a Vue-Component, do not forget to also import it inside the Parent Instance
As reminder, props are those data values that you pass to a child as a HTML Tag Attribute (:propName=data) and slot is the data between the HTML Opening and Closing tag.
Learning by doing – VueJS Practice part 2. Let’s take a look at how a possible school-like question on your VueJS Test would look like. And how you would go about solving it. Btw if you want to dive deep into VueJS 2, take a look at our VueJS Certificate Course.
You need to create routes for the Vue-Components that we created in the previous VueJS Practice. Create a vue-route (use Vue-Router) for each of the following Components:
AssetsDetail.vue and AssetsList.vue
ProductsDetail.vue and ProductsList.vue
UsersDetail.vue and UsersList.vue
Routes for “*Detail.vue” Components must have a url parameter “id”. Router for “*List.vue” Components must have a url parameter “page”. Also, create a Vue Component called “navigation/TopMenu.vue” where you generate a list of router-links to the previously created routes; use a programmatic approach.
Vue-Router is the obvious choice for a simple routing task like this.
Regarding URL Parameters you cheat by reading about Dynamic Routing at Vue-Router Official Docs.
VueJS Practice – Solution
To define your router with Vue-Router, you need to write your routings to router.js. Here is how our prototype looks like.
The TopMenu.vue Component has two benefits. First, it helps you debug your router.js while you are creating your routes configuration. Second, you can import the TopMenu to the most Upper VueComponent. This ways, if a route changes, your will have adjust the TopMenu.vue only, and the whole App will be updated. This is what i came up with for the Menu.
