Consequences of not using a lang attribute in an html5 html tag
(1 answer)
Closed 5 years ago.
I just wanted to ask if the tag is really that important... Do I need to use it if I am developing a website?
Will it affect my code if I don't put it?
It's important for accessibility reasons, not codewise.
It's mainly used for translations "bot".
If you really want it to be perfect, then use <html lang="en-US"> or the appropriate country code for your language (like mine is fr-FRand not fr-CA since there are differencies between those two languagues).

How to use HTML5 features with XHTML
(2 answers)
Closed 4 years ago.
I have seen on several occasions that some companies are looking for web developers who know how to program in html5 and xhtml. I wonder why they specify xhtml. I do not know if these languages are used separately or if you can join strengths in the same file.
I'm sorry if my English is not very good and if my question is novice. Thank you
XHTML is an older architecture based on html4, it's possible to keep old applications alive

There are a lot of people who are afraid of copyright infringement, but as mplungjan said
If you put it on the web, it will be available to look at.
And that, unfortunately for you, is the case for every site from Google to Stack Overflow.
If there are any bad cases of your site being plagiarized you should think of suing.

Uppercase or lowercase doctype?
(7 answers)
Closed 7 years ago.
Does DOCTYPE have to be in uppercase in HTML5?
The start of an HTML5 document is usually written as:
<!DOCTYPE html>
...but is the lowercase also valid?
<!doctype html>
In HTML, the DOCTYPE is case insensitive.
You can find more info here: https://www.w3.org/TR/html5/syntax.html#the-doctype
Unlike earlier versions of HTML, in HTML5 the doctype declaration is case-insensitive. In other words works as well as . Check here: http://www.html-5-tutorial.com/doctype.htm

I'm learning HTML via a workbook that I've paid for. In it it says "An HTML5 document can be written using HTML or XHTML syntax"...Is this true? I thought an HTML5 document could only be written in HTML5!? I know that by using <!DOCTYPE html> I'm declaring that the document is written in HTHL5. I know XHTML has a different document declaration, so it's not like I'm going to head up my page with <!DOCTYPE html> and then use XHTML as my syntax...
What this means is that you can use XHTML syntax if you like. For example, both of these are fine:
<meta charset="utf=8">
<meta charset="utf=8" />
The single doctype of:
<!DOCTYPE html>
covers both. They are BOTH HTML5!
Where you really need to be careful though is that ONLY elements that are defined as elements with no content are allowed to use the self-terminating syntax. This would be elements like: img, br, meta and link. If an element is declared in the spec. as a content element, it can't be self-terminated:
<p /> is incorrect

Does my HTML5 doctype have to be on the VERY first line?
(6 answers)
Closed 9 years ago.
Is it valid to have blank line returns preceding the doctype declaration?
The <!DOCTYPE> declaration must be the very first thing in your HTML
document, before the <html> tag.
via w3schools
Not necessarily; BOM, whitespace and comments may come first.
http://www.w3.org/TR/html-markup/documents.html#syntax-document-html
So yeah, it must come first, before any actual HTML tags, but note that you can't really ever put doctype before BOM.
