How To Run Html Program In Visual Studio Code
Fabulously Favuzza
Visual Studio Code, often abbreviated as VS Code, is an open-source code editor developed by Microsoft. It supports a variety of programming languages, including HTML (HyperText Markup Language), which is the standard markup language for documents designed to be displayed in a web browser.
In this context, 'markup language' means a system for annotating a document in a way that is visually distinguishable from the content. Think of it like marking up a script for a play where you highlight different characters' lines in different colors. HTML helps determine the structure and layout of a web page, much like how an architect's blueprint determines the layout of a building.
This is a basic HTML document structure. It includes a declaration (which tells the browser that this is an HTML5 document), an element (which contains the whole HTML document), a element (which contains meta-information about the document), a element (which specifies a title for the document), and a element (which contains the document's content).
You don't "run" HTML code in the same way you run programs written in languages like Python or JavaScript. HTML is a static language, meaning the browser reads the file and renders the content as described by the HTML tags.
If you don't see the 'Open with Live Server' option, it means you need to install the Live Server extension. Go to the Extensions view (the square icon on the left sidebar), search for 'Live Server' and click Install. This handy extension allows you to run a local development server and live reload feature for static and dynamic pages.
One of the great features of using VS Code and Live Server is the ability to see your changes in real time. When you make changes to your HTML file in VS Code, those changes are immediately reflected in your browser.
Congratulations! You've now learned how to write and run HTML code in Visual Studio Code. Remember, programming is a skill that improves with practice. Don't be afraid to experiment with different HTML tags and attributes to see how they affect the look of your webpage. Happy coding!
Remember, understanding HTML and being comfortable with VS Code is the first step towards web development. As you become more confident, you can start exploring other technologies such as CSS (Cascading Style Sheets) and JavaScript to add style and interactivity to your web pages.
Visual Studio Code provides basic support for HTML programming out of the box. There is syntax highlighting, smart completions with IntelliSense, and customizable formatting. VS Code also includes great Emmet support.
It supports configuration of hue, saturation and opacity for the color that is picked up from the editor. It also provides the ability to trigger between different color modes by clicking on the color string at the top of the picker. The picker appears on a hover when you are over a color definition.
You can fold regions of source code using the folding icons on the gutter between line numbers and line start. Folding regions are available for all HTML elements for multiline comments in the source code.
Tip: The formatter doesn't format the tags listed in the html.format.unformatted and html.format.contentUnformatted settings. Embedded JavaScript is formatted unless 'script' tags are excluded.
If you'd like to use HTML Emmet abbreviations with other languages, you can associate one of the Emmet modes (such as css, html) with other languages with the emmet.includeLanguages setting. The setting takes a language identifier and associates it with the language ID of an Emmet supported mode.
You can extend VS Code's HTML support through a declarative custom data format. By setting html.customData to a list of JSON files following the custom data format, you can enhance VS Code's understanding of new HTML tags, attributes and attribute values. VS Code will then offer language support such as completion & hover information for the provided tags, attributes and attribute values.

Recently, I finished the videos regarding "Adding Images to the Page" in the HTML section of Treehouse. I went onto my editor (Visual Studio Code), though, to try it on my own, and I couldn't figure out how to move a picture from my computer onto the practice website I was trying to build.
So assuming you've created a .html document in Visual Studio Code with the necessary markup, you can add images to your own practice page by using the tag. You can then define the location of the image using the src attribute within that tag.
Keep in mind that in this instance, the .html document should be located in the parent directory of the images folder. If the image is located in the same folder as the .html document, you would simply use the file name like so:
After teaching myself for a year I started coding full time when I joined the Founders and Coders web development bootcamp in March 2020. Two weeks into the course we went into lockdown in the UK and our cohort had to go remote for the remaining 16 weeks. Thanks to the collaborative power of the VS Code Live Share extension we were still able to pair program and go through the syllabus as planned, but one of the things we missed out on from not being in person was organically sharing the little tips and tricks that you would normally pick up from working next to each other.
You can watch someone demonstrate something while sharing their screen, but unless you see them typing on the keyboard you don't necessarily pick up on the key presses that could also save you seconds of your day! As a result there are a lot of nifty VS Code tricks that I have learned since starting my first role as a Full Stack Developer that I wish I had know during the course.
I compiled these into a talk for the next Founders and Coders cohort, entitled "Why The F*** Didn't I Know This Sooner?!", and I also wanted to share them here for those starting out on their own coding journeys.
Emmet gives you some default abbreviations for a range of file types including .html and .css which expand into useful code snippets. Emmet support is built into VS Code so it does not require downloading an extension.
I made !! into a custom shortcut for my VS Code editor that includes the tag for SEO, as well as the tags for for linking CSS stylesheets and JavaScript files, and a few other frequently used semantic tags.
I would recommend writing out the desired structure into an HTML file first, and then you can copy it into a tool like this to parse your HTML file into a JSON string with escaped characters to get the right indentation.
Sometimes you can spend longer learning to type out shortcuts than if you just manually typed the code. I personally don't find Emmet abbreviations a time saver for writing CSS, but some of the HTML abbreviations I find useful include:
This extension gives you a shortcut for getting the relative filepath of another file from your current file. This is really helpful in a large codebase with lots of nested folders where you have a lot of imports and exports between files, for instance in a React.js project.
What I do use it for is the Git blame feature, which annotates the most recent commit history for each line in your files. This is especially useful when working on a group project so you can see at a glance when the last changes were made, who made them, and the relevant commit message.
Prettier is a lifesaver because it automatically formats your code! You can download it as an extension on VS Code, and it will run your settings that you configure in the application (go to Settings and search for 'Prettier').
It's a good idea to have a .prettierrc config file in the root folder of your group projects where you specify how many spaces you want for intentation, single or double quotes, whether all lines should finish with a semi-colon, etc.
Into this, with consistent spacing, an average line width of roughly 80 characters, 2 spaces for indentation and not tabs, semicolons printed at the end of every statement, and double quotes instead of single quotes:
This is just an example to demonstrate the formatting changes Prettier applies, and is not a recommendation of code style. Most of the time you won't have to play around with the settings too much and you can go with the basic config to keep your codebase consistent, or when you start working as a developer your company will already have a "house style".
I am not exactly sure what causes conflict but I know if configured properly Emmet can do wonders with JSX too. It worked fine few times but then it started messing up. I could not push much time into finding the cause.
Visual Studio is an integrated development environment (IDE) developed by Microsoft. It is used to develop computer programs including websites, web apps, web services and mobile apps. Visual Studio uses Microsoft software development platforms including Windows API, Windows Forms, Windows Presentation Foundation (WPF), Windows Store and Microsoft Silverlight. It can produce both native code and managed code.
Visual Studio supports 36 different programming languages [citation needed] and allows the code editor and debugger to support (to varying degrees) nearly any programming language, provided a language-specific service exists. Built-in languages include C,[6] C++, C++/CLI, Visual Basic .NET, C#, F#,[7] JavaScript, TypeScript, XML, XSLT, HTML, and CSS. Support for other languages such as Python,[8] Ruby, Node.js, and M among others is available via plug-ins. Java (and J#) were supported in the past.
The most basic edition of Visual Studio, the Community edition, is available free of charge. The slogan for Visual Studio Community edition is "Free, fully-featured IDE for students, open-source and individual developers". As of February 19, 2024[update], Visual Studio 2022 is a current production-ready version. Visual Studio 2013, 2015 and 2017 are on Extended Support, while 2019 is on Mainstream Support.[9]
