I want to add a multiple attribute to a select in .net. I have done this:
If MultiSelect Then
drpSelect.Attributes.Add("multiple", "true")
End If
Though strictly speaking the html should be just multiple.
For the "boolean" html attributes (the ones that should consist of just a name without a value, like required or multiple) an accepted alternative is to use name="name", like multiple="multiple".
In your case you should code
drpSelect.Attributes.Add("multiple", "multiple")
See also W3C:
Boolean attributes may legally take a single value: the name of the
attribute itself.

This is the same question as this. But since I'm not using javascript, 'innerText' is not a solution for me and I was wondering if it was possible for regex to combine /(<.*?>)/g and /\S+/g to get the actual word count without having to make a bunch of string operations.
The language I'm using here is Dart, if a solution I haven't found already exist within it that would work too as an answer. Thanks !
Edit : Someone edited the tags ? This question is not Dart-specific and is about regex, so I'm putting them back as they were.
Edit 2 : The question was closed because it is not "focused", but I do not know how I can make "if it was possible for regex to combine /(<.*?>)/g and /\S+/g" any more focused.
Assuming all text is enclosed in HTML elements, you can use (?<=>|\s)[^<\s>='"]+?(?=<|\s).
With the string <p>One</p><p>Two Three, Four. Five</p><p>Six</p> there are six matches.
Note:
It uses a lookbehind group, which might not be supported in all browsers.
Punctuation at the end of words are grouped with them, e.g. "three," so keep that in mind if you're planning to use the actual words and not just count them.

In What order should you declare “id” and “class” for the same HTML element, and why ? It seems that my questions is reported for being a duplicate, but mine is referring to a specific H1 HTML element in this case. Thank you
<h1 id="orange-text" class="pink-text blue-text">Hello World!</h1>
There is no predefined order for the attributes in terms of passing w3c validation... it's completely up to you. Any order of HTML attributes will have no effect on performance either.
Order is not important, both of them works correctly. But I always add "id" before "class" because I think is easier to read and the "id" provide more information.

As a HTML5 beginner, I would like to know if it is necessary to use an ID for all html elements I use ?
No, you only need to use an ID if you want to target that element or its children for style or script purposes.
No.
You might need to use it,when you need to work with it like ->
To link to an element with a specified id within a page
To style text with CSS

A perfect example is stackoverflow. When a user types a question, the textarea give the user basic formatting options such as bullet points, numbering, italicize, etc. How can I create a similar textarea? I am currently using html, css and php.
You can use javascript (or more effectively jQuery) to create your own textarea with this behaviour, or look at an existing package such as TinyMCE and configure it to meet your requirements (the approach I would suggest): http://www.tinymce.com/
Easiest way would be to use an editor like TinyMCE: http://www.tinymce.com/
There are others as well, but TinyMCE is what I see used most.

I need a regular expression to help me close the <br> tag to comply with the xhtml standard. In my html br does not always comes empty, so the regex has to account for it. Thanks in advance for your help.
Look for this pattern
(\<br[^\>]*)(\/)?(\>)
And replace with this
$1/$3
Based on the engine you may need to use \1/\2 instead of $1/$3 in the replacement string.
The regex might also look a bit simpler:
replace
/<br.*?>/i
with
<br\/>
