Dev Ed has a number of courses on YouTube. I have been viewing on named HTML and CSS Tutorial.
I have Visual Studio Code installed and added the packages suggested in the Tutorial. I get to the point where the <!DOCTYPE html> tag has been created and on a new line the tag <html> has been typed. This automatically completes the end tag, hence <html></html>. If I am understanding this correctly, Ed then says hit the Tab key but it just produces spacing as you would normally expect with a Tab.
My expectation is that it formats the code as follows:
<html>
</html>
This does not happen.
According to VSCode release notes, such a feature has been removed from the IntelliSense and replaced with </.
In order to autocomplete your tags you can do either of these:
Use ctrl + space to select from provided items in the suggestion list.
Use third party plugins like this.
Save your file as .html or if already have done that, click on the text between CRLF and smiley face and select HTML

We used to be able to type ! inside an html document in vscode to get html boiler plate content completion as documented here.
However it no longer works. Thoughts?
I noticed that if we type ! and select Edit > Expand Abbreviation, the ! is replaced with boilerplate, but I no longer get the intellisense that was there before.
Update
Looks like we need to do ctrl+shift+p and search for User Settings. Filter for the emmet settings and select the Trigger expansion on tab then the ! is replaced with the corresponding emmet snippet.
I also selected Show suggestions as snippets, but the intellisense / snippet is still not showing up.
If you want to get html boilerplate with Emmet Abbreviation, you should type html:5 and hit tab.
I have faced this issue in visual studio.
Step-1:
try below steps in url. https://marketplace.visualstudio.com/items?itemName=sidthesloth.html5-boilerplate
Step-2:
if it worked : "cheers .!"
else:
it could be issue with select language mode. on the bottom of visual studio next to LF on your screenshot select language mode and change it to html.
Thanks & Regards, Surya kiran.
The issue was with Language mode only. You will get the option to select the Langauage mode on the bottom.
Been very annoyed for many, many long minutes by the boilerplate shortcut's suddenly, inexplicably not working (maugre much extension-de-installing and intalling and re-installing, even with VS Code uninstalls and re-installs, but what I'm come up with from mining various forums (what does seem to work and doesn't appear to be settings-dependent or peculiar to my laptop) is:
COMMAND+K plus COMMAND+L (one can just HOLD COMMAND and type K and then L sequentially).
In the Emmet Abbreviation window that comes up type ! as usual and then press Enter/Return.
Simply striking ! will bring up the boilerplate. One can then simply press Enter to return to the code.
The two-stroke process of ! + TAB is now replaced by the only marginally more involved five-stroke process of ⌘ + K + L + ! + Enter.
For me it was the "<" problem
this is not working: <html
this is working: html
After a recent update to VS Code the familiar why of getting a html boilerplate failed. You could add a index.html to the file explore and the window would open for its content.
Using Shift and the exclamation mark key would produce it. That is no longer the case instead create your file in the explore. When it opens the window type html, you will receive a dropdown to select from instead.
enter image description here
I experienced this issue after configuring my VS Code environment for an online course. In my case, the behavior was due to the following pair being added to my settings.json file:
"emmet.showExpandedAbbreviation": "never"
After I removed this, the shortcuts returned.
I am looking for the shortcut keys that I should use to autocomplete the structure of the HTML.
So for instance, when I type html and press a few keys the following structure should appear:
<!DOCTYPE html>
<html>
<head>
<title> </title>
</head>
<body>
</body>
</html>
Note: I am using a MAC
"!" After typing, press the "TAB" key on the keyboard.
Perhaps you should look into templates for your IDE, for example in Sublime Text you have snippets which I would recommend looking into.
However, there is another workflow that you are able to use using a toolkit such as Emmet. The feature that you specifically want in Emmet is called "Expand Abbreviation". Essentially, you type out "CSS like" strings, put your caret at the end of the string and hit tab and Emmet will parse it into HTML. For example, the following string:
!doctype>html>(head>title)+(body)
will compile to the above (with a trailing closing tag of </!doctype> which is a bit awkward. However Emmet is quite clever and we can go one step further.. so expanding:
html:5
Will actually give you
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
</body>
</html>
Which is pretty much what you were looking for! And if you want to take it another step further, Emmet also supports expanding ! which is an alias for html:5. Only one character.
Check out Emmet's cheat sheet for more little bits.
In TextMate these are called snippets and they can easily be assigned a tab completion shortcut;
Select Bundles » Edit Bundles… in the TextMate 2 menu.
Select the bundle you want to add a snippet to, e.g. HTML. Press Cmd-N to create a new bundle item, and select Snippet.
Select Menu Actions
Press Command + N to create a new item, select snippet.
In the text area copy and paste your template.
On the drawer there's a field for "Tab Trigger", enter "html" there.
Save.
Now when you type "html" and press tab, your snippet will be inserted.
More info about creating a snippet.
Note: I've added "$0" in between your body tags. This is a tab stop and your cursor would appear at the $0. You can read more about advanced Snippet features here.
In My Humble Opinion;
html doesn't tab complete already because there's no good way to anticipate what you would want in your html template.
Sure, Emmet (as #bitten suggests in his answer) gives you something, but html:5 does too much; HTML5 does not mandate a html, head, or body tag. See this Stack post about HTML5's optional tags. Please see bitten's comment for some warranted concerns with this approach.
That said, I do use Emmet and it is worth investigating.
As for just inserting the doctype for HTML5 in TextMate, just type doctype and Tab.
click ! and after tab and you'll get the structure.
I find on sublime 3 that if I autocomplete code I sometimes get an extra angular bracket.
for example, If I start writing "<ht", I get an option to autocomplete the html tag, but the code produced looks like this:
<<!DOCTYPE html> <!-- Extra angle bracket here -->
<html>
<head>
<title></title>
</head>
<body>
</body>
</html>
Which is quite annoying. How do I fix this? I'm not sure on what other autocompletion it does this. I'd like to start using the feature more once I know how it works and if I can adjust it to my style
Don't start off the tag with <. Just type ht and then press Tab, and you'll have your desired result. The same goes for any other tag.
p + Tab will create <p></p>, etc.
It may be that you have a conflicting package. I had this issue with the "HTML5 Bundle" but as soon as i removed it the problem went away. Hope that helps
I just uninstall the HTML5 package from Package Control (Ctrl + Shift + P)/ Type "Remove Package" and select the packages related to HTML and it works!
Okay, so I found your solution, but keep in mind, it might bug in the coming updates.
First goto your installation destination and open the folder Packages, in there open HTML.sublime-package as archive and copy all the content in a seperate folder on your desktop. In that new folder, edit the file html.sublime-snippet and change
<content><![CDATA[<!DOCTYPE html>
To
<content><![CDATA[!DOCTYPE html>
This should solve your problem.
I write an application and inside of HTML code I have custom tags (of course these tags are parsed on server side and end user gets them as valid HTML code). Example of custom tag usage:
<html>
<body>
...
<Gallery type="grid" title="My Gallery" />
...
</body>
</html>
1.) How can I have eclipse recognize my custom tags inside of HTML code and add syntax highlighting to them?
2.) How can I add auto-suggestions to my custom tags? For example if I type "<Gallery " press "Ctrl+Space" - in the list of available attributes it shows me "type" and "title" and if I type "<Gallery type=" press "Ctrl+Space" I would see list of available values only for tag "Gallery" and its attribute "type".
Thanks in advance!
Not really what you want, but maybe it helps you:
You can try the Aptana Plug-in for Eclipse. It allows to write your own regular expression for HTML validation, so a custom tag would be ignored by the validator.
E.g.:
.gallery.
Eclipse allows you to add simple auto-suggestions via Templates. On
Eclipse 3.7.1 (Indigo) + PHP Dev Tools (PDT) 3.0.0: Window > Preferences > Web > HTML Files > Editor > Templates
Sadly, there is no easy way: you have to roll your own parser for this, and then add both your extra elements and the base grammar (HTML) to it.
If you have your parser, you could use it to do syntax highlighting (strictly speaking, for that simple lexing is enough); and a good parser can support content assist (auto-suggestions in your terminology).
Caveats:
Creating a parser for HTML is not an easy task. Maybe by aiming at a more often used subset is feasible.
If a parser exists, the editor parts are still hard to get well.
Some help on the other hand: you could use some text editor generators to ease your work:
Eclipse IMP http://www.eclipse.org/imp/ can in theory handle any type of parser, but currently it is most optimized for LPG. The documentation is scarce, but the developers are helpful in the forums.
Xtext http://www.eclipse.org/Xtext/ got quite a hype for creating text editors for DSLs. The generated editors are quite nice out of the box, but is not the best solution for large files. Has a really helpful developer community.
EMFText http://www.emftext.org/index.php/EMFText is a lesser known entity - I don't know it in details, but I guess, it is similar to Xtext.
I know its been a long time since this Q was asked,
but I hope this might help others like myself that reach this in search of a solution.
So, When using Eclipse (Mars.1 Release (4.5.1) - and possibly earlier - I did not check).
Go to Window - Prefrences
Then in the dialog that opens go to Web - HTML Files - Editor - Validation.
On the right side:
under Ignore specified element names in validation and enter the list of custom elements you use. (e.g. Gallery,tab,tabset,my-element-directives-*)
you might also like to go under Ignore specified attribute names in validation do the same for your custom attributes.(e.g. ng-*,my-attr-directives-*)
Two things to note:
After letting eclipse do a full validation you must also close the file and reopen it to have the warnings removed from the source code.
Using this method would ignore those attributes under any element. I don't think there is a simple way to tell it to ignore some-attribute only if its a child of some-element.
I find templates are an ok alternative but let's see if we can encourage a more robust solution; please take a moment and vote for this: https://bugs.eclipse.org/bugs/show_bug.cgi?id=422584
You need to add a new HTML template.To add a new template, complete the following steps:
1) From the Window menu, select Preferences.
2) In the Preferences page, select Web and XML > HTML Files > HTML Templates.
3) Click New.
4) Enter the new template name and a brief description of the template.
5) Using the Context drop-down list, specify the context in which the template is available.
6) In the Pattern field, enter the appropriate tags, attributes, or attribute values (the content of the template) to be inserted by content assist.
7) If you want to insert a variable, click the Variable button and select the variable to be inserted. For example, the word_selection variable indicates the word that is selected at the beginning of template insertion, and the cursor variable determines where the cursor will be after the template is inserted in the HTML document.
8) Click OK to save the new template.
You can edit, remove, import, or export a template by using the same Preferences page.

I've been editing a lot of HTML pages with basic text editor, notepad.
When I went to validate them the validation service is saying there's a div tag that is not closed. I tend to find automatic error reports such as these don't tend to be too reliable, i.e they will give you a line number and the error but often times the error is actually in another part of the file entirely.
I'm just wondering if there is a way to find the closing tag for an opened HTML tag. For example, you click on a tag then click a shortcut, and the program will jump to the closing tag. I know this functionality is in homesite, but I don't have homesite, and its a bit of a bulky program anyway.
To sum up, I would like to know how to find html tags that don't have closing tags.
If you save your HTML as page.xhtml (instead of page.html), the browser (Firefox/Chrome or Opera) should find the un-closed tags for you without the need for a validator. Just remember to rename them .html before serving them online - IE doesn't support .xhtml files yet.
Edit (3 years later): This post's still getting comments/upvotes so a slight amendment. IE9 and IE10 do now support xhtml files.
Use the firefox view source - wrong code will be in different color
Notepad++ - never had any problems with it and also never had any unclosed html tag with it.
You can just click on any element and see if it has a closing tag. Also you can do this: click on "TextFX"(left from plugins in navigation) -> click on "Text FX HTML Tidy" -> click on lets say hmm "TiDy clean Document - wrap". That should fix your html document, aka close all unclosed elements.
http://validator.w3.org/
Does more than just unclosed tags. Should be used by all front-end developers, IMO.
I am using two online-tool, which work very fine.
jona.ca and tormus.com
CSE HTML Validator Lite is a free lightweight editor (for Windows) that will check your HTML (just press F6) and find missing end tags and other problems. You can also press Ctrl+M on a start tag or end tag and it will take you to the matching start or end tag.
A simple online service that will also do this (and more) is OnlineWebCheck.com. There are other online services but in my opinion the one I just mentioned is the simplest one to use and understand.
Full disclosure: I am the developer of CSE HTML Validator Lite and http://www.OnlineWebCheck.com/ which is based on CSE HTML Validator.
If your code is very messy, not prettified nor indented, v.Nu (as seen at https://validator.w3.org/nu/) will often get confused (for instance if there's an extre closing tag, it may not manage to select the one which is really wrong).
One solution is code folding: by collapsing all the code which is marked as a child of a certain node, you can often easily spot some incorrect hierarchy.
An example of editor which supports code folding is Kate editor: see the arrows on the left in their screenshot.
free lightweight html editors ... online html validation services that can highlight unclosed tags?
Use linter-vnu.
linter-vnu is a package for the Atom editor that uses the Nu Html Checker (v.Nu) to validate HTML or XHTML documents.
Disclosure: I am the developer of linter-vnu.
linter-vnu uses another Atom package, linter, to integrate v.Nu and Atom.
For example, if you open the following test.html file in Atom:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">
<head>
<meta charset="utf-8"/>
<title>Test HTML document</title>
</head>
<body>
<div>
<p>Lorem ipsum dolor sit amet...</p>
</body>
</html>
(with a deliberately missing closing </div> tag)
then Atom (or rather, linter-vnu, thanks to linter and v.Nu) displays the following error messages:
Unclosed element “div”. at line 8 col 1 in test.html
End tag for “body” seen, but there were unclosed elements. at line 10 col 1 in test.html
and marks those lines in the editor with red dots.
If you click the "at..." (hyperlinked text) in the error message, the editor insertion point moves to the corresponding line, and a popup appears under the line, with the error text ('Unclosed element "div".').
If you save your HTML document with the file extension .xhtml, and open it in Atom, then v.Nu validates your document as XHTML (XML) rather than HTML, with slightly different messages. In this case, just one error message:
required character (found “b”) (expected “d”) at line 10 col 3
where line 10 contains the closing </body> tag. v.Nu was expecting a </div> tag instead; it was happy with </ - it was expecting a closing tag - but it was expecting the element name to begin with "d" for "div", not "b" for "body".
I make the following claims, as of November 2016:
v.Nu is the best option for validating (X)HTML(5).
linter-vnu is the best option for interactively harnessing v.Nu in an editor. linter-vnu itself is trivial; it's just a few lines of "glue" code. What makes it the best option is the Atom editor and the Atom linter package.
I welcome counterclaims and questions about these claims. I'd be happy to be proven wrong and be shown something better. Especially if, like v.Nu and linter-vnu, it's free.
