How to display HTML tags as plain text [duplicate]
(11 answers)
Closed 2 years ago.
I would like to know how to write EXACTLY <h2> in HTML? Because every time I write <h2> in HTML it acts as an element. But I want <h2> as it is on my website.
I presume you want to write <h2> in HTML.
See, h2 in Stackoverflow (Stackoverflow renders some html tags, h2 included): <h2> actual text: <h2>
< is the less than symbol escaped
> is the greater than symbol escaped
< > in html:
<!DOCTYPE html>
<html>
<head>
<title>Show H2</title>
</head>
<body>
<p><h2></p>
</body>
</html>
To output the H2 without parsing as a tag. You would use like below..
<h2>
If you want to show HTML code on your website, you have to escape the less-than and greater-than symbols. E.g:
<H2>
< is the escaped version of '<'. And > is the escaped version of '>'.

printing "<html>" using html
(10 answers)
Closed 1 year ago.
I have a plain <p> tag in my HTML. Inside this HTML tag I am trying to output text as follows:
Place this code tag in the header of your website between <head> ...
</head> in your page to show the notice to activate the functionality.
When I put this text inside the <p> tag as follows:
'<p>Place this code tag in the header of your website between <head> ... </head> in your page to show the notice to activate the functionality.</p>'
I render this wrong output:
Place this code tag in the header of your website between ... in your page to show the notice to activate the functionality.
As you can see the output did not print the ' head ' part.
How can I fix it?
Convert the < and > into the entities < and >. See also https://dev.w3.org/html5/html-author/charref
Example:
<p>Place this code tag in the header of your website between <head> ... </head> in your page to show the notice to activate the functionality.</p>
To escape a character in html you need to use the ASCII value of that caracter so for the < and the > this is < and >
<p>Place this code tag in the header of your website between <head> ... </head> in your page to show the notice to activate the functionality.</p>

How to show <div> tag literally in <code>/<pre> tag?
(11 answers)
Closed 2 years ago.
When i say this, i mean how do i make a specific piece of code show not as part of the actual website, but as a demonstration for others to see?
There are various ways to do so
You may use <pre></pre> tag
<pre>
your-code
</pre>
using special <code> tag
<pre>
<code>
your-code
</code>
</pre>
you may like to use the HTML code within
<![CDATA[<your-code>]]>
use any syntax highligtening library e.g. prettify or syntaxhighlighter
You will have to use:
The <pre> - Preformatted tag to display the html text
The < - Less than tag in place of < tag in your code
The > - Greater than tag in place of > tag in your code.
i.e <div> shall be replaced by <div>
Brief example
<pre>
<!DOCTYPE html>
<html>
<body>
<h1>The code element</h1>
<p>The HTML <code>button</code> tag defines a clickable button.</p>
<p>The CSS <code>background-color</code> property defines the background color of an element.</p>
</body>
</html>
</pre>
<pre>
<code>
you code here
</code>
</pre>

Does HTML5 change the standard for HTML commenting?
(2 answers)
Closed 5 years ago.
I'm reviewing some code and I've run across an instance where the developer has added a placeholder for an Angular component.
<div>
<!someAngularComponent/>
</div>
This behaves exactly as if <someAngularComponent/> were wrapped in the standard <!-- --> structure for comments.
Putting a single ! at the beginning of the tag seems to have some special meaning - see https://stackoverflow.com/a/16324326/217490. Is this usage a valid way to comment out elements, or is it working mostly by side effect?
Some browsers may support it as a comment, but it's not valid HTML. You can run the code through the W3C's validator to see: https://validator.w3.org/nu/#textarea
<!doctype html>
<html>
<head>
<title>Test</title>
</head>
<body>
<div>
<!someAngularComponent/>
</div>
</body>
</html>
This will raise an error:
Error: Bogus comment.
At line 8, column 3
body ↩ div ↩ !someAngularComp
Depending on your audience, you may have to test it in multiple browsers, but I'd probably just recommend the standard comment syntax so there's no risk.

Do browsers remove whitespace in between text of any html tag
(3 answers)
Closed 5 years ago.
I have the following HTML:
<html>
<body>
hi hi
<br>
<span> hi hi </span>
</body>
</html>
My expectation is that there would be spaces before the hi hi which correspond to the spaces before them in the span. However, The spaces are not being rendered in Chrome:
How come space characters are not rendering in my span?
The output is a HTML webpage, and in HTML multiple spaces are collapsed to a single space. Spaces at the begining and end of the tag aren't visible.
You could solve this with css:
.showSpaces{
white-space: pre;
}
and set the class in the html
<span class="showSpaces"> hi hi </span>
Full example
.showSpaces{
white-space: pre;
}
<html>
<body class="showSpaces">
hi hi
<br>
<span> hi hi </span>
</body>
</html>
Another option is to use the <pre> tag in HTML.
Use the non-breaking space html entity:
Using CSS to move your text over is probably better practice in your example.
My expectation is that there would be spaces before the hi hi which
correspond to the spaces before them in the span.
by default, only one whitespace is provided in between words even if you apply more spaces. one way to overcome the issue is to use non-breaking space .
<span> hi hi </span>
though this is not the purpose of .
a more suitable option would be to use the pre tag.
snippet:
<html>
<body>
hi hi
<br>
<span><pre> </pre>hi hi </span>
</body>
</html>

What Is the Difference Between a Tag and an Element?
(3 answers)
Closed 6 years ago.
What are the differences between a tag and an element in HTML 5? Can someone give me a detailed explanation between both?
I'm asking this question because I see a lot of confusion on the web and even on the W3C website, where it is used interchangeably yet presented in a manner where it is different without further clarification.
So Far, from my understanding:
Tags:
In HTML there are two types of tags: paired tags and unpaired tags. A paired tag consists of text in-between a start tag and an end tag. An unpaired tag only contains a start tag.
Elements:
Have the same description as tags but with a different name.
An Element consists of both tag and content. The elements starts with a tag then content and then closing tag.
paragraph Tag:
<p>
paragraph Element:
<p>content</p>
For a universal definition check here:
https://dev.w3.org/html5/html-author/#elements
An HTML fime consists of elements. Each element has a tagname. Some examples of elements with paired tagnames are:
- div
- p
- head
- body.
Some examples of unpaired tagnames are:
- br
- img
- link
In this example of an HTML file you can see a few elements with each its correct tagname:
<!DOCTYPE html>
<html>
<head>
<title>basic page</title>
<head>
<body>
<h1>This is a title</h1>
<p>This is a paragraph</p>
</body>
</html>
