The last lesson was the beginning of a new "column" in which I answer questions, give directions, opine on matters that I have seen that are sought after by visitors to the site. Here we will talk a little about the new tags in HTML5, the differences with those of HTML4, the point of them, advantages and disadvantages of their use.
First let me clarify that in this lesson we'll talk really about HTML5, and not everything new that is associated with it. Let's start with the fact that the new JS API-th, offered by modertine browsers and CSS3 are separate technologies still widely put under one common denominator with all the new opportunities offered by developing Internet standards . It is this definition - developing Internet standards - is the correct one. Although many people, realtek however, to keep the technical "order" in speeches, etc., personally I'm ready to talk about the common denominator HTML5, as it is short and speaks more to a wider audience than JS, CSS and "developing Internet standards."
Let's go back though the actual HTML5 and new tags that are available realtek in it. For a complete realtek list is always best to consult Google, as I did myself just as there are guides and do not have anything to remember - somewhere it says. Surely, you can find a list of new tags in HTML5, presented in w3schools.com. You will not look at all of them, but only those which most emphasis from the very offer to be included in the new stardart. <header>, <footer>, <section>, <article>, <aside>, realtek <nav>
What are themselves these tags and what should realtek be used? I think it's easy person to figure out what it is used, because the tags are simple words in English, which I assume everyone has heard of one place or another, even if you do not know English. <header> realtek is designed to replace <div id="header">, that May-May occur at any site. Even if no precise DIV ID with a value of HEADER (although in about 90% if not more, of the cases so), there will have a header container to your site. The idea is this tag (as well as others listed earlier) realtek to facilitate the processing of the search engines the information on our website, so that they more easily and more accurately provide information to the people who use them and want to search for names in actual content of the site, and not something that is mentioned in passing realtek in the header and not found anywhere else.
<article> should be used to separate the section of the site with its own comprehensive idea and "history." In blogove is very easy to determine what is "article" us, but also for many other sites we an item to categorize in a similar realtek way - if we can electronically store a product it enclosed in <article>, if present Calendar list of events, each event can again be closed in <article>. The idea is that it is finished, autonomy and semantic completeness.
<aside> is one of the most confusing tags, because the meaning of its name can make us think that is designed to sidebars (sidebar-s). Even in one of the first lessons about who the new tag for what should be used, I had read that it was designed precisely for this purpose. Yes but later began to go explain how actually realtek <aside>, should be used for additional and minor elements. Those who might carry more information to the article, but by themselves are not directly engaged with the content and could not be ignored. Surely you've read newspaper articles, along which there are small sections of photos or interesting information for person / place / whatever-and-be-is spoken of in the article, but by themselves, these sections are not relevant to the actual content, which can be read independently. The idea of <aside> is precisely that.
<nav> last tag of this group, we will discuss. It is designed to incorporates site navigation (be it primary or secondary) - without any additional complex requirements. <meter>, <progress>, <mark>, <time>, <output>
Although it is difficult to give a definition of the group of these tags tentatively digress from the front (whether for their display: inline by default browsers that support them or something - does not matter).
<meter> tag is a little confusing, as in itself not a special presentation of the contents, but the idea is to introduce a scalar quantity of known maximum. Or in other words - its going to be used to express rates. Places realtek I've ever met recommendations JavaScript to be replaced obiknoviniya <m
