     HTML is a Markup Language not a programming language, so it can't connect directly to any database.

     But you can send the form's action of you login.html to the same of the login.php of blesta and add the same name of each input.

   • How to make login authentication page in HTML or JAVASCRIPT

     Top Answer

     Answered Jan 30, 2016 · 10 votes

     HTML and Javascript are interpreted on the client side. For login purposes, it is the server side code that is commonly used to verify the credentials - simply because that fact that you are already aware of - with a simple client side implementation, you can see the credentials in source code, server side is also easier to work with, once you understand it, it is more flexible for further development, it is more secure, and it is really used everywhere for this task.

     It is a good idea to use PHP, ASP, Ruby (or any other server side language) for this. If you do not want that, you need to make it hard for the user to read the credentials from the source code.

     In order to do that, you can use various methods like cryptography or obfuscation. Cryptography is highly recommended over obfuscating as it provably adds more security to your application. Obfuscating basically means that you change the source code in a way that it is hard to read - you add functions that encode strings, so that your "password" can not be spotted on the first sight. However, obfuscation can always be bypassed, and usually quite easily with a good debugging tools.

     So, let's go with cryptography. What you are looking for here is using one way hash functions. You have plenty to choose from - MD5, SHA1, SHA256, ... each provides different level of security. SHA256 implementation in Javascript is an example you can use. There are many other libraries and examples for this, so just use Google and find the one that you like.

     Now, what to do with it? Say you have sha256() function that accepts a string and returns its hash as a string. For each user and password you have, you precount SHA256 hash of string "user + password".

     Say, you want your username to be "Pedro" and password for this account is "MyPassword".

     You precount the hash of "PedroMyPassword" - e.g. with with online hashing tool. You can see the its SHA256 hash is

     40be6e939eedf018b2b846e027067dcb006585a2155ce324f1f2a6a71d418b21-

     This hash is what you put into your Javascript code.

     When the user enters their user and password, you call your sha256 function on "username + password" and you compare it to your precounted hash.

     Note that you have to select really strong password, otherwise certain attacks (such as dictionary attack) would be easy to use to break your hash.

     The problem is now, that you did not specify, what you want to do next. For example, you might want to redirect authenticated users to next page, but here you have the same problem again - if you have redirection in Javascript to "secondpage.html" in your code, someone could just skip the authentication and navigate to this second page directly.

     What you can do in this case is that you name your second page as

     40be6e939eedf018b2b846e027067dcb006585a2155ce324f1f2a6a71d418b21.html-

     i.e. the hash of your user+pass string. In this variant you do not put the hash in the code at all. The web server will just return error 404 for all users that fail to authenticate. For example, if someone attempts to use "Pedro" with "123456" as password, the SHA256 would be

     3bac31720fdd4619ebe2e8865ccc0dc87eb744f3f05f08c628bb9217a77e4517

     and if you redirect them to

     3bac31720fdd4619ebe2e8865ccc0dc87eb744f3f05f08c628bb9217a77e4517.html

     it won't exist, because your second page file is called

     40be6e939eedf018b2b846e027067dcb006585a2155ce324f1f2a6a71d418b21.html-

     You would need to create these second pages for each user/pass combination. You could then put a simple redirection code to the real second page.

     But make sure you are using HTTPS protocol, otherwise, the second pages would go through the wire unencrypted ...

     This all will work, but still, I highly suggest, you consider the server side way.

   • How to make a HTML Page in A4 paper size page(s)?

     Top Answer

     Answered Jun 09, 2021 · 435 votes

     Ages ago, in November 2005, AlistApart.com published an article on how they published a book using nothing but HTML and CSS. See: http://alistapart.com/article/boom

     Here's an excerpt of that article:

     CSS2 has a notion of paged media (think sheets of paper), as opposed to continuous media (think scrollbars). Style sheets can set the size of pages and their margins. Page templates can be given names and elements can state which named page they want to be printed on. Also, elements in the source document can force page breaks. Here is a snippet from the style sheet we used:

     @page { size: 7in 9.25in; margin: 27mm 16mm 27mm 16mm;}

     Having a US-based publisher, we were given the page size in inches. We, being Europeans, continued with metric measurements. CSS accepts both.

     After setting the up the page size and margin, we needed to make sure there are page breaks in the right places. The following excerpt shows how page breaks are generated after chapters and appendices:

     div.chapter, div.appendix { page-break-after: always;}

     Also, we used CSS2 to declare named pages:

     div.titlepage { page: blank;}

     That is, the title page is to be printed on pages with the name “blank.” CSS2 described the concept of named pages, but their value only becomes apparent when headers and footers are available.

     Anyway…

     Since you want to print A4, you'll need different dimensions of course:

     @page { size: 21cm 29.7cm; margin: 30mm 45mm 30mm 45mm; /* change the margins as you want them to be. */}

     The article dives into things like setting page-breaks, etc. so you might want to read that completely.

     In your case, the trick is to create the print CSS first. Most modern browsers (>2005) support zooming and will already be able to display a website based on the print CSS.

     Now, you'll want to make the web display look a bit different and adapt the whole design to fit most browsers too (including the old, pre 2005 ones). For that, you'll have to create a web CSS file or override some parts of your print CSS. When creating CSS for web display, remember that a browser can have ANY size (think: “mobile” up to “big-screen TVs”). Meaning: for the web CSS your page-width and image-width is best set using a variable width (%) to support as many display devices and web-browsing clients as possible.

     EDIT (26-02-2015)

     Today, I happened to stumble upon another, more recent article at SmashingMagazine which also dives into designing for print with HTML and CSS… just in case you could use yet-another-tutorial.

     EDIT (30-10-2018)

     It has been brought to my attention in that size is not valid CSS3, which is indeed correct — I merely repeated the code quoted in the article which (as noted) was good old CSS2 (which makes sense when you look at the year the article and this answer were first published). Anyway, here's the valid CSS3 code for your copy-and-paste convenience:

     @media print { body{ width: 21cm; height: 29.7cm; margin: 30mm 45mm 30mm 45mm; /* change the margins as you want them to be. */ } }

     In case you think you really need pixels (you should actually avoid using pixels), you will have to take care of choosing the correct DPI for printing:

     • 72 dpi (web) = 595 X 842 pixels
     • 300 dpi (print) = 2480 X 3508 pixels
     • 600 dpi (high quality print) = 4960 X 7016 pixels

     Yet, I would avoid the hassle and simply use cm (centimeters) or mm (millimeters) for sizing as that avoids rendering glitches that can arise depending on which client you use.

     It would be fairly easy to force the web browser to display the page with the same pixel dimensions as A4. However, there may be a few quirks when things are rendered.

     Assuming your monitors display 72 dpi, you could add something like this:

     <!DOCTYPE html><html> <head> <style> body { height: 842px; width: 595px; /* to centre page on screen*/ margin-left: auto; margin-right: auto; } </style> </head> <body> </body></html>

     A4 size is 210x297mm

     So you can set the HTML page to fit those sizes with CSS:

     html,body{ height:297mm; width:210mm;}
