Landing page with adaptive design and country recognizing from database



Below you can see one my small MVC project for one special Landing with adaptive design. In this project I work as full stack programmer, including job of html layout engineer, therefore firstly I describe front-end of this project. This project need to work extremely fast, therefore I create it without any script, only on CSS.



1. Front-End.

What is adaptive design? My CSS file contains six different parts, six different html markup.


   1:  html, body {
   2:      padding: 0px;
   3:      font-family: Cuprum;
   4:      max-width:100%;
   5:      overflow-x:hidden;
   6:  }
   7:   
   8:   
   9:  #copyright p {
  10:      color: white;
  11:  }
  12:   
  13:  @media only screen and (max-width: 320px) {
  14:      #content {
  15:          background-image: url("../Images/Phone.jpg");
 ...:  
 123:  }
 124:   
 125:  @media only screen and (min-width: 320px) and (max-width: 480px) {
 126:      #content {
 ...:  
 235:  }
 236:   
 237:  @media only screen and (min-width: 480px) and (max-width: 768px) {
 238:      #content {
 239:          background-image: url("../Images/Tablet.gif");
 ...:  
 352:  }
 353:   
 354:  @media only screen and (min-width: 768px) and (max-width: 1920px) {
 355:      #content {
 ...:  
 470:  }
 471:   
 472:  @media screen and (min-width: 1920px) and (max-width: 2560px) {
 473:      #content {
 ...:  
 580:  }
 581:   
 582:  @media screen and (min-width: 2560px) {
 583:      #content {
 ...:  
 694:      }
 695:  }

Each html markup has own background with different positioning of html-elements, for example this is different view with width less than 480 and more than 480.



In line 200-207 I arrange buttons in vertically, in 316-323 I arrange buttons horizontally.


 ...:  
 125:  @media only screen and (min-width: 320px) and (max-width: 480px) {
 126:      #content {
 ...:  
 200:      #twobutton {
 201:          position: relative;
 202:          top: 330px;
 203:          display: inline-block;
 204:          width: 230px;
 205:          height: 140px;
 206:          /*border: 1px solid red;*/
 207:      }
 ...:  
 209:      #selectukraine {
 210:          background: url(../Images/480-UkraineSelect.gif) no-repeat left top;
 211:          width: 230px;
 212:          height: 58px;
 213:          border-radius: 8px;
 214:          cursor: pointer;
 215:          float: left;
 216:      }
 217:   
 218:      #selectrussia {
 219:          background: url(../Images/480-RussiaSelect.gif) no-repeat left top;
 220:          width: 230px;
 221:          height: 58px;
 222:          border-radius: 8px;
 223:          cursor: pointer;
 224:          float: right;
 225:          margin-top: 20px;
 226:      }
 ...:  
 236:   
 237:  @media only screen and (min-width: 480px) and (max-width: 768px) {
 316:      #twobutton {
 317:          position: relative;
 318:          top: 400px;
 319:          display: inline-block;
 320:          width: 475px;
 321:          height: 62px;
 322:          /*border: 1px solid red;*/
 323:      }
 ...:  
 327:      #selectukraine {
 328:          background: url(../Images/768-UkraineSelect.gif) no-repeat left top;
 329:          width: 230px;
 330:          height: 58px;
 331:          border-radius: 8px;
 332:          cursor: pointer;
 333:          float: left;
 334:      }
 335:   
 336:      #selectrussia {
 337:          background: url(../Images/768-RussiaSelect.gif) no-repeat left top;
 338:          width: 230px;
 339:          height: 58px;
 340:          border-radius: 8px;
 341:          cursor: pointer;
 342:          float: right;
 343:      }

Each button has rollover, I define it in this way:



 227:   
 228:          #selectrussia:hover {
 229:              background-position: left bottom;
 230:          }
 231:   
 232:          #selectukraine:hover {
 233:              background-position: left bottom;
 234:          }

2. Admin panel design. Loading IP database.

For this project I have created simple Admin panel in classic ASP.NET.

3. Admin panel authentication .

For this project I decide simple authentication with define user in config file and to work without user database. I restrict access to admin user.


  24:    <system.web>
  25:      <customErrors mode="Off" />
  26:      <compilation debug="true" targetFramework="4.5.1" />
  27:      <httpRuntime targetFramework="4.5.1" maxRequestLength="20000000" executionTimeout="300" />
  28:      <authentication mode="Forms"></authentication>
  29:      <membership>
  30:        <providers>
  31:          <clear />
  32:          <remove name="AspNetSqlMembershipProvider" />
  33:        </providers>
  34:      </membership>
  35:    </system.web>
  36:    <location path="~/Admin">
  37:      <system.web>
  38:        <authentication mode="Forms">
  39:          <forms loginUrl="~/Admin/Login.aspx" timeout="2880" defaultUrl="~/Admin/Default.aspx">
  40:            <credentials passwordFormat="Clear">
  41:              <user name="XXXXXXXXXXXX" password="YYYYYYYYYYY" />
  42:            </credentials>
  43:          </forms>
  44:        </authentication>
  45:        <authorization>
  46:          <deny users="?" />
  47:        </authorization>
  48:        <membership>
  49:          <providers>
  50:            <clear />
  51:            <remove name="AspNetSqlMembershipProvider" />
  52:          </providers>
  53:        </membership>
  54:      </system.web>
  55:    </location>

Each page before beginning must check user authentication.



And this is my login page.

4. Loading IP CSV-file to database.

For this project I pay database in https://www.ip2location.com/

After that I define a database in MS SQL. Firstly I plain upload IP4 and IP6 database, but little bit later I decides to limit myself only IP4 database, but there is definition to both tables (IP6 database has more precision than support MS SQL, therefore I store data in binary form).


   1:  CREATE TABLE [dbo].[IP4](
   2:      [I] [int] IDENTITY(1,1) NOT NULL,
   3:      [IP_FROM] [bigint] NOT NULL,
   4:      [IP_TO] [bigint] NOT NULL,
   5:      [COUNTRY_CODE] [char](2) NOT NULL,
   6:   CONSTRAINT [PK_IP4] PRIMARY KEY CLUSTERED 
   7:  (
   8:      [I] ASC
   9:  )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
  10:  ) ON [PRIMARY]
  11:   
  12:  GO
  13:   
  14:  CREATE TABLE [dbo].[IP6](
  15:      [I] [int] IDENTITY(1,1) NOT NULL,
  16:      [IP_FROM] [varbinary](39) NOT NULL,
  17:      [IP_TO] [varbinary](39) NOT NULL,
  18:      [COUNTRY_CODE] [char](2) NOT NULL,
  19:   CONSTRAINT [PK_IP6] PRIMARY KEY CLUSTERED 
  20:  (
  21:      [I] ASC
  22:  )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
  23:  ) ON [PRIMARY]
  24:   
  25:  GO

And this is a form to uploading ip2location CSV-file to my database. For this task I have to filtered data and stored IP only for Ukraine and Russia.

5. Cache IP database to memory.

Initially I use ORM Linq-to-SQL, but little bit later I have rebuild this site to EF. Below you can see a screen with EF6 and three magic string to upload IP-database to site memory.



It is reasonable, because database is not huge.



6. Get IP4 from IP6 address.

If I decide to use only IP6, I create this module to analyze any IP addr adn select IP4 from app possible IPs.


  31:      Public Shared Function GetIP4Address() As String
  32:          Dim IP4Address As String = String.Empty
  33:   
  34:          For Each IPA As IPAddress In Dns.GetHostAddresses(HttpContext.Current.Request.UserHostAddress)
  35:              If IPA.AddressFamily.ToString() = "InterNetwork" Then
  36:                  IP4Address = IPA.ToString()
  37:                  Exit For
  38:              End If
  39:          Next
  40:   
  41:          Return IP4Address
  42:   
  43:      End Function
  44:  End Class

7. Get Country by IP.

Pay attention to calculation in string 16 - this is more than integer !


   1:  Imports System.Net
   2:  Imports BraggartES
   3:  Friend Class GetCountry
   4:   
   5:      Public Shared Function FromIP4(Ip As String) As String
   6:          Dim IP4 As List(Of IP4)
   7:          If HttpContext.Current.Application("IP4") Is Nothing Then
   8:              Dim db1 As New BrgUaEntities
   9:              HttpContext.Current.Application("IP4") = db1.IP4.ToList
  10:          End If
  11:          IP4 = HttpContext.Current.Application("IP4")
  12:          Dim IpArr1() As String = Ip.Split(".")
  13:          Dim Res As Integer = 0
  14:          If IpArr1.Length = 4 Then
  15:              If Integer.TryParse(IpArr1(0), Res) And Integer.TryParse(IpArr1(1), Res) And Integer.TryParse(IpArr1(2), Res) And Integer.TryParse(IpArr1(3), Res) Then
  16:                  Dim IpValue As Int64 = CLng(IpArr1(0)) * 256 * 256 * 256 + CLng(IpArr1(1)) * 256 * 256 + CLng(IpArr1(2)) * 256 + CLng(IpArr1(3))
  17:                  Dim Z = (From X In IP4 Select X Where X.IP_FROM <= IpValue And X.IP_TO >= IpValue).ToList
  18:                  If Z.Count > 0 Then
  19:                      Return Z(0).COUNTRY_CODE
  20:                  Else
  21:                      Return "NO"
  22:                  End If
  23:              Else
  24:                  Return "NO"
  25:              End If
  26:          Else
  27:              Return "NO"
  28:          End If
  29:      End Function

8. MVC controller code

In string 59-62 I define a model to communicate with view.


   1:  Public Class HomeController
   2:      Inherits System.Web.Mvc.Controller
   3:   
   4:      Dim db1 As BrgUaEntities
   5:      Dim Seo As List(Of Seo)
   6:   
   7:      Function Index() As ActionResult
   8:          If HttpContext.Application("Seo") Is Nothing Then
   9:              db1 = New BrgUaEntities
  10:              Seo = db1.Seos.ToList
  11:          Else
  12:              Seo = HttpContext.Application("Seo")
  13:          End If
  14:          ViewBag.Title = (From X In Seo Select X Where X.SeoType = "PageTitle").First.SeoValue
  15:          ViewBag.Description = (From X In Seo Select X Where X.SeoType = "PageDescription").First.SeoValue
  16:          ViewBag.Keywords = (From X In Seo Select X Where X.SeoType = "PageKeywords").First.SeoValue
  17:          '
  18:          Dim RequestIP4 As String = GetCountry.GetIP4Address
  19:          Dim Country As String = "NO"
  20:          If Not String.IsNullOrEmpty(RequestIP4) Then
  21:              Country = GetCountry.FromIP4(RequestIP4)
  22:          End If
  23:          '
  24:          Dim Model = New MvcModel
  25:          'Country = "NO"

  29:                  If CBool(ConfigurationManager.AppSettings("RussiaReady")) Then
  30:                      Model.RussiaLink = (From X In Seo Select X Where X.SeoType = "RussiaLink").First.SeoValue
  31:                  Else
  32:                      Model.RussiaLink = "/Home/Russia"
  33:                  End If
  34:                  Model.UkraineLink = (From X In Seo Select X Where X.SeoType = "UkraineLink").First.SeoValue
  35:                  Return View("SelectCountry", Model)
  36:              Case "RU"
  37:                  Model.Label = (From X In Seo Select X Where X.SeoType = "RussiaText").First.SeoValue
  38:                  If CBool(ConfigurationManager.AppSettings("RussiaReady")) Then
  39:                      Model.Link = (From X In Seo Select X Where X.SeoType = "RussiaLink").First.SeoValue
  40:                  Else
  41:                      Model.Link = "/Home/Russia"
  42:                  End If
  43:                  Return View("Russia", Model)
  44:              Case "UA"
  45:                  Model.Label = (From X In Seo Select X Where X.SeoType = "UkraineText").First.SeoValue
  46:                  Model.Link = (From X In Seo Select X Where X.SeoType = "UkraineLink").First.SeoValue
  47:                  Return View("Ukraine", Model)
  48:              Case Else
  49:                  Return View("Index", Model)
  50:          End Select
  51:      End Function
  52:   
  53:      Function Russia() As ActionResult
  54:          Return View("RussiaClosed")
  55:      End Function

  65:      Public Property UkraineLink As String
  66:      Public Property RussiaLink As String
  67:  End Class

9. Layout page and Views.

This is layout page with CUPRUM font definition and title setting in admin system and stored in DB.


   1:  <!DOCTYPE html>
   2:  <html>
   3:  <head>
   4:      <meta charset="utf-8" />
   5:      <meta name="viewport" content="width=device-width, initial-scale=1.0">
   6:      <meta name="description" content="@ViewBag.Description">
   7:      <meta name="keywords" content="@ViewBag.Keywords">
   8:      <title>@ViewBag.Title</title>
   9:      <link href="https://fonts.googleapis.com/css?family=Cuprum" rel="stylesheet">
  10:      @Styles.Render("~/Content/css")
  11:      @Scripts.Render("~/bundles/modernizr")
  12:  </head>
  13:  <body>
  14:          <div id="content">
  15:              >@@RenderBody()
  16:              <div id="copyright">
  17:                  <p>Braggart.es</p>
  18:              </div> 
  19:          </div>
  20:  </body>
  21:  </html>


And this is some another view of this smallest site.


   1:  @Code
   2:      Layout = "~/Views/Shared/_Layout.vbhtml"
   3:      @ModelType MvcModel
   4:  End Code
   5:   
   6:  <form action="@Model.Link">
   7:      <input id="angel" type="submit" value="" />
   8:  </form>
   9:   
  10:  <div id="label">@Model.Label</div>
  11:   
  12:  <div id="onebutton">
  13:      <form action="@Model.Link">
  14:          <input id="goukraine" type="submit" value="" />
  15:      </form>
  16:  </div>


This site is extremely small, another my sites has hundreds of forms, please see for example:

but this site is so instructive, therefore I decide to describe it.
