You have created a Web page in HTML. When it fails W3C validation, you try changing the HTML standard to make your code more com

solniwko [45]

Answer:

<table>

Explanation:

W3C validation is a test applied to web pages codes, containing HTML, CSS and other important web frameworks, to make sure that they follow the right syntax and semantics prescribed by the W3C - World Wide Web Consortium.

When a web page, or simple an HTML document, passes this test then it shows that the set rules for creating web pages, that can be easily rendered across many browsers, have been well followed.

There are many reasons why the test may fail. Some of them are highlighted as follows;

i. Not specifying the Doctype at all. For an HTML document to pass the W3C validation test, it is important to specify the Doctype which tells the browser how to treat the document. If HTML is specified as Doctype, then the browser treats the document as HTML. If none is specified, the browser does not know and may have to guess how to treat the document.

ii. Missing closing tags. HTML is a markup language and the use of tags are very important. Many tags have opening and closing parts such as;

<p> </p>.

Some are self closing such as;

<br />

Now, opening a tag and not closing it will make the test fail.

iii. Not completing important child tags. Some tags have child tags that are very important. Child tags are put inside another tag called the parent tag. An example is the <table> tag which has a few child tags such as <tr>, <tbody> e.t.c

Now, when creating a table, according to the W3C specifications, one or more of the <tr> or <tbody> child tag should be inserted.
