There is a W3C Quality Assurance tip about this topic: <h1> is the HTML element for the first-level heading of a document: If the document is basically stand-alone, for example Things to See and Do in Geneva, the top-level heading is probably the same as the title. If it is part of a collection, for … Read more
No, Ian Hickson (HTML spec editor) is convinced that this is a CSS problem, not an HTML one: This shouldn’t be necessary. It’s a limitation of CSS. The right solution is for CSS to provide some pseudo-element or other mechanism that introduces an anonymous container into the rendering tree that wraps the elements you want … Read more
The English phrase “Everything but the kitchen sink” means “almost anything one can think of”. Looking at the first 8 Google results for github kitchen sink, it’s pretty clear that it’s generally used for demo applications which showcase all (or almost all) of the features of an API, generally for use by developers who’re learning … Read more
I’m glad you’re starting by asking about a specification rather than implementation first. There are a lot of ideas floating around about what FRP is. From the very start in the early 90’s (when I was working in interactive graphics at Sun Microsystems and then Microsoft Research), it has been about two properties (a) denotative … Read more
You might want to check out this paper: Sentence similarity based on semantic nets and corpus statistics (PDF) I’ve implemented the algorithm described. Our context was very general (effectively any two English sentences) and we found the approach taken was too slow and the results, while promising, not good enough (or likely to be so … Read more
You can only place <h2> elements within <a> elements if you’re working with HTML5, which allows any other elements within <a> elements. Previous specifications (or current ones however you want to look at them) never allowed this. The usual way of doing this is to place <a> within <h2>. This works, has always worked, and … Read more
It’s a parameter expansion, it means if the third argument is null or unset, replace it with what’s after :- $ x= $ echo ${x:-1} 1 $ echo $x $ There’s also another similar PE that assign the value if the variable is null: $ x= $ echo ${x:=1} 1 $ echo $x 1 Check … Read more
Syntax is the grammar. It describes the way to construct a correct sentence. For example, this water is triangular is syntactically correct. Semantics relates to the meaning. this water is triangular does not mean anything, though the grammar is ok. Talking about the semantic web has become trendy recently. The idea is to enhance the … Read more
UL means “unordered list”. OL means “ordered list”. UL gets you bullet points. OL gets you numbers. Definitely not interchangable.
As I state in my comment and you quote in the W3C, h1 is a heading and not a title. Each sectioning element can have its own heading element(s). You cannot think of h1 as being the title of a page only but as the heading of that particular section of the page. Just like … Read more
