Visual Studio Code Php In Html
Velasco Thibault
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:
My front-end web projects start as a HTML file, gradually expanding into JavaScript and CSS files as required. A few months ago, I found there was a way to auto-populate the boilerplate HTML code that gives the basic structure for a page in Visual Studio Code: the html, head, body tags, as well as some accompanying meta information in the head tag. When I first saw this feature, I was excited. I could save some time by using this! But, I could not recall how I triggered the code expansion.
I went back to writing the code manually, or trying to rely on GitHub Copilot ^1 to do it for me (although the speed improvements of this method compared to writing the code manually were negligible at best).
After further research, this is an Emmet abbreviation, a shortcut in the Emmet syntax to expand concise text into full code in a web application. I have not explicitly used Emmet before but their homepage makes me curious. ^2 It looks like you can make custom abbreviations, too.
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.
The only issue I still have is I have some JavaScript files with front matter and Liquid and those cause error warnings. Now I tried setting setting the language of all .js files to jekyll too, but that disables JavaScript syntax highlighting. My workaround:
I did all this a while ago and believed this to be correct, so my apologies if there is anything in error. Using these extensions and the JSON file extensions, you should be able to add Shopify/Liquid commands to any html or markdown file without first having to inform VSC you want to use the language.
You mention that you see errors with JS+Liquid. I am not using any of that in my code (it is a purely static site). What I would try is adding another extension to the files.extensions area. I have not tested this, but I recommend you set it up like the following example and give it a try:
To open DevTools in Visual Studio Code in Debug mode by using the DevTools UI, right-click an .html file or click the Launch Project button, as described in Opening DevTools and the DevTools browser. You can also use the Visual Studio Code UI for launching the Debugger, such as F5, to open the DevTools tabs as well, if you define a DevTools-compatible launch.json file by clicking the Generate launch.json button in the Microsoft Edge Tools Side Bar.
Right-click an .html file in Explorer > Open with Edge. This approach essentially uses a file path rather than a URL, and doesn't require you to generate a launch.json file.
You can open the Edge DevTools: Browser tab (the embedded DevTools browser) as part of a debugging session. The DevTools extension opens a new browser as an embedded browser in Visual Studio Code. This Devtools: Browser tab can be moved anywhere within the editor. You can use this tab side by side with your source code, or split the panes and have the browser preview below your code:
You can use the DevTools extension with the usual Visual Studio Code debugging UI/workflow, as follows. In this approach, to enter Debug mode, we are not using the DevTools UI; we are not right-clicking an .html file to select Open with Edge, and we are not clicking the Activity Bar > Microsoft Edge Tools > Launch Project button.
JavaScript debugging is built in to Visual Studio Code; you can debug in Chrome, Microsoft Edge, or Node.js without installing extensions. If you debug by using the Microsoft Edge option with the Visual Studio Code debugging features and UI, you can start Microsoft Edge DevTools from the JavaScript debugger. If the DevTools extension isn't installed, you're prompted to optionally install it.
