海外TECH	DEV Community	Inside the head of an HTML document	https://dev.to/abi/inside-the-head-of-an-html-document-53e8	Inside the head of an HTML documentIn a HTML document the lt head gt is the place where you put everything that s not content This is where you tell the browser how to render your page and what other files like CSS or JS or fonts to download It s also where you tell a search bot or a social media website like Facebook or Twitter about your website Let s walk through one by one all the things you should include in your lt head gt Browser DirectivesFirst up is lt meta charset utf gt It directs the browser to treat all your HTML content as UTF and not ASCII or some character encoding such as ISO I don t think this is strictly necessary if you already have lt DOCTYPE html gt at the top of the file specifying that this document is an HTML document HTML only supports UTF And even if you remove the doctype and include lt meta charset ISO gt Chrome still treats it as UTF but other browsers might not leading to potentially unpredictable behavior So the consensus is that you should always include this tag A mobile optimized website should include lt meta name viewport content width device width initial scale gt Without this tag the mobile browser might render the page at desktop width say px and then scale the page down to fit the actual width of the device likely something much smaller like px It will end up looking super zoomed out With this tag however things work as expected The media query breakpoints you ve set for lower widths will return true and the page will render as you intend it to on a smaller device SEOThen we have lt title gt which controls the text in the tab bar of the browser It s also very important for SEO It ends up being the Google search result s title For SEO reasons it is recommended that it s as close to characters as possible It also ends up being the default name under which the bookmark gets saved as in a user s browser lt meta name description content gt is important for SEO reasons as well Recommend length is characters I like to include lt meta name robots content follow index gt although the default behavior of most search engine bots is to follow links and index all pages so technically it s optional but doesn t hurt to be explicit The canonical URL is really important for SEO reasons lt link rel canonical href gt It lets the search engine know that canonical URL for the content on this page is the value specified using this tag That way I can syndicate this blogpost on dev to and Medium but still have Google direct people to this page when my content ranks highly for a search keyword So your actual website ends up getting the traffic rather than dev to or Medium Another reason this matters is that large scale duplication can lower your search ranking With canonical URLs you are telling Google when something is a duplicate vs not Make sure you have consistent canonical URLs across your website trailing slashes or not www subdomain or not HTTPS or not pick HTTPS What about the keywords tag lt meta name keywords content seo search engine optimization gt I ve seen a lot of websites use them but the consensus in the SEO community is For of people the meta keywords tag is useless and filling it out is a waste of time You should only use it if you have a particular reason to do so like using it for an internal keyword tagging system or an internal site search Most search engines including the biggest one of them all Google disregard the tag For more SEO tweaks I generate a free report here It ll check many of the things described above The Google Search Console is also very helpful Social MediaWhen a link gets shared on Twitter this is how it looks The Open Graph meta tags are what the website uses to render this tile lt meta property og title content Loops gt lt meta property og site name content Loops gt lt meta property og url content gt lt meta property og description content Analyze Solana transactions Trace how NFTs and tokens move across multiple accounts gt lt meta property og type content website gt lt meta property og image content PUBLIC URL og image png gt Title site name URL and description pretty much just correspond to lt title gt website domain or name canonical URL and lt meta name description gt respectively The type can be a few different types but typically it s either article for a blogpost or website for an app or an e commerce website For the image Facebook recommends x or larger is preferred up to MB Stay close to a aspect ratio to avoid cropping But I ve found that following the image guidelines is no substitute for actually testing the previews To test I use ngrok to tunnel my local website to the public internet and copy the URL into this tool to look at the previews across platforms Open Graph tags are used by most social platforms including Twitter However for Twitter you are able to specify Twitter specific tags as well Twitter will use title description from the Open Graph tags so I don t bother re specifying them But there are some Twitter specific tags worth including lt meta name twitter card content summary large image gt lt meta name twitter site content abi gt Summary card with large image is likely what you want for articles and websites but if you have a video instead you can specify player Twitter s image recommendation for the summary card with large image is slightly different from Facebook Images for this Card support an aspect ratio of with minimum dimensions of x or maximum of x pixels Images must be less than MB in size JPG PNG WEBP and GIF formats are supported Only the first frame of an animated GIF will be used SVG is not supported However since the aspect ratio is only slightly from Facebook you can probably skip using a different image Besides the testing tool linked earlier Facebook and Twitter offer their own tools as well Facebookand Twitter OthersThe only remaining thing we must include is a bevy of favicons Here s a great article by the author of PostCSS on what we need and why lt link rel icon href favicon ico sizes any gt lt × gt lt link rel icon href icon svg type image svg xml gt lt link rel apple touch icon href apple touch icon png gt lt × gt lt link rel manifest href manifest webmanifest gt And then in the manifest webmanifest file icons src icon png type image png sizes x src icon png type image png sizes x If your app is a progressive web app i e a website that can be installed to the home screen without using an App Store you should fill out the manifest file with more detail	2022-05-03 01:13:06
