But note that in some cases, the script may need to be placed in the head of your document, because you want it to take effect before the browser starts rendering the page. Thus, most scripts should be placed at the very bottom of the page, so that theyвЂ™ll only be parsed after the rest of the page has loaded. This results in the page appearing to load much more slowly when large scripts are included at the top of the page before any content. When a browser encounters a script, it will pause downloading and rendering the rest of the page while it parses the script. Placing the element at the bottom of the page is for the purposes of the page-load speed. Likewise with script elements, youвЂ™ll see them almost anywhere in a document, but theyвЂ™re usually at the bottom (just before the closing tag) as a best practice. And unlike older versions of HTML, thereвЂ™s no need to include a type attribute (which was never needed in the first place). A stylesheet can be included anywhere in a document, but youвЂ™ll customarily see it inside the. The stylesheet is included using the element with an appropriate rel attribute. The last two significant portions of our HTML template are the reference to a stylesheet and script. For example, below is what would appear in a tweet if you included a link to GitHubвЂ™s home page: When you see a post shared on social media, youвЂ™ll often see these bits of data automatically added to the social media post. For example, the five elements included here will appear in social cards embedding the following data: The ones weвЂ™re including here will enhance the appearance of the web page when itвЂ™s linked in a social media post.

You can view a full list of available Open Graph meta options on the Open Graph website. These are the ones youвЂ™re likely to use most often. These elements take advantage of something called the Open Graph protocol, and there are many others you can use. The next section in our HTML5 boilerplate includes some of those meta element options: Open Graph Meta Elements for Social CardsДЄs mentioned, all meta elements are optional but many have benefits for SEO and social media marketing. ThereвЂ™s much more we could write about this subject, but for now, weвЂ™re content to accept this simplified declaration and move on to the next part of our document. It should also appear before any content-based elements (like the element that appears later in our example). Note: to ensure that certain older browsers read the character encoding correctly, the entire character encoding declaration must be included somewhere within the first 512 characters of your document. Nonetheless, if you want to delve a little deeper, you can read about character encoding in the HTML specification. A full explanation of character encoding is beyond the scope of this article, and it probably wonвЂ™t be that interesting to you, either. In nearly all cases, utf-8 is the value youвЂ™ll be using in your documents. This is an optional feature and wonвЂ™t cause any warnings in validators, but itвЂ™s recommended for most HTML pages: The first line inside the section of an HTML document is the one that defines the character encoding for the document. In fact, you can use one of the older doctypes with new HTML5 elements on a page and the page will render the same as it would if you used the new doctype. ItвЂ™s really up to the browser to determine feature support on a case-by-case basis, regardless of the doctype used. In other words, the doctype alone isnвЂ™t going to make your pages compliant with modern HTML features. ThereвЂ™s never going to be an вЂњHTML6вЂќ, so itвЂ™s common to refer to the current state of web markup as simply вЂњHTMLвЂќ.Д«ecause browsers are required to support older content on the Web, thereвЂ™s no reliance on the doctype to tell browsers which features should be supported in a given document. Although the current iteration of web markup is known as вЂњHTML5вЂќ, it really is just an evolution of previous HTML standards - and future specifications will simply be a development of what we have today.

YouвЂ™ll notice that the вЂњ5вЂќ is conspicuously missing from the declaration. The doctype can be written in uppercase, lowercase, or mixed case. With the advent of HTML5, those indecipherable eyesores are gone and now all you need is this: Many years ago, the doctype declaration was an ugly and hard-to-remember mess, often specified as вЂњXHTML StrictвЂќ or вЂњHTML TransitionalвЂќ. The doctype should always be the first item at the top of any HTML file. In the case of HTML files, it means the specific version and flavor of HTML. A doctype is simply a way to tell the browser - or any other parser - what type of document itвЂ™s looking at. Your HTML5 template needs to start with a document type declaration, or doctype.
