Syntax - Syntax sass

Sass merupakan salah satu compiler css yang sangat populer, untuk dapat menggunakan sass sebagai compiler css, kita harus menginstallnya terlebih dahulu, lihat disini.

Berikut beberapa syntax sass dan perbandingannya dengan css biasa,

Parent and child

//sass
.test{
    position: absolute;
    border: 4px solid black;
    top: 200px;
    left: 25%;
    width: 50%;
    height: 200px;
    text-align: center;
    span{
      font-size: 24px;
      line-height: 200px;
    }
}
//css
.test span {
  font-size: 24px;
  line-height: 200px;
}

Use one parameter

//sass
.test {
  font-family: 'Pacifico', cursive;
  height: 400px;
  background-image: url("lemonade.jpg");
  border:{
    top: 4px solid black;
    bottom: 4px solid black;
  }
}
//css
.test {
  font-family: 'Pacifico', cursive;
  height: 400px;
  background-image: url("lemonade.jpg");
  border-top: 4px solid black;
  border-bottom: 4px solid black;
}

Use variable

//sass
$translucent-white:rgba(255,255,255,0.3);
$standard-border: 4px solid black;
.test{
 background-color: $translucent-white;
 border: $standard-border;
}
//css
.test{
 background-color: rgba(255, 255, 255, 0.3);
 border: 4px solid black;
}

Use mixin

//sass
@mixin transform($transformation) {
  transform: $transformation;
  -webkit-transform: $transformation;
  -moz-transform: $transformation;
  -ms-transform: $transformation;
  -o-transform: $transformation;  
}
.test {
 width: 300px;
 height: 180px;
 &:hover{
  @include transform (rotatey(-180deg));  
 } 
}
//css
.test {
  width: 300px;
  height: 180px;
}
.test:hover {
  transform: rotatey(-180deg);
  -webkit-transform: rotatey(-180deg);
  -moz-transform: rotatey(-180deg);
  -ms-transform: rotatey(-180deg);
  -o-transform: rotatey(-180deg);
}

Variable on mixin

//sass
$stripe-properties: to bottom, 15%, blue, white;
@mixin stripes($direction, $width-percent, $stripe-color, $stripe-background: #FFF) {
  background: repeating-linear-gradient(
    $direction,
    $stripe-background,
    $stripe-background ($width-percent - 1),
    $stripe-color 1%,
    $stripe-background $width-percent
  );
}
.test {
 width: 100%;
 height: 100%;
 @include stripes($stripe-properties...);
}
//css
.test {
  width: 100%;
  height: 100%;
  background: repeating-linear-gradient(to bottom, white, white 14%, blue 1%, white 15%);
}

Use String

//sass
@mixin photo-content($file) {
  content: url(#{$file}.jpg); //this is ruby???
  object-fit: cover;
}
.image {
    @include photo-content('titanosaur');
    width: 60%;
    margin: 0px auto;  
}
//css
.image {
  width: 60%;
  margin: 0px auto;
  object-fit: cover;
  content: url(titanosaur.jpg);
}

Hover in mixin

//sass
@mixin hover-color($color) {
   &:hover{
       color: $color;
   }
}
.test {
 display: block;
 text-align: center;
 position: relative;
 top: 40%;
 @include hover-color(red);
}    
//css
.test:hover {
  color: red;
}

You can use your math skill

//sass
.test {
  color: red+blue;
}
//css
.math {
  color: magenta; //hahahaha
}

//other math
$width:250px;
.math {
  width: $width;
  border-radius: $width/6;
}
//css
.math{
  width:250px;
  border-radius: 41.66667px;
}

Looping

//use each
$list: (orange, purple, teal);
@each $item in $list { //shit this code same with ruby hahaha,.,.
  .#{$item} {
    background: $item;
  }
}
//css
.orange {
  background: orange;
}
.purple {
  background: purple;
}
.teal {
  background: teal;
}

//use for
$total: 10;
$step: 360deg / $total;
.test {
  height: 30px;
}
@for $i from 1 through $total {
  .test:nth-child(#{$i}) {
    background: adjust-hue(blue, $i * $step);
   }
}
//css
.test {
  height: 30px;
}
.test:nth-child(1) {
  background: #9900ff;
}
.test:nth-child(2) {
  background: #ff00cc;
}
.test:nth-child(3) {
  background: #ff0033;
}
.test:nth-child(4) {
  background: #ff6600;
}
.test:nth-child(5) {
  background: yellow;
}
.test:nth-child(6) {
  background: #66ff00;
}
.test:nth-child(7) {
  background: #00ff33;
}
.test:nth-child(8) {
  background: #00ffcc;
}
.test:nth-child(9) {
  background: #0099ff;
}
.test:nth-child(10) {
  background: blue;
}

Import scss

//import other scss files
@import "test";

Engine - Create graph or chart

Hello everyone,,

Tutorial kali ini codedoct akan membagikan cara membuat grafik / chart menggunakan highcharts pada php.

Grafik atau chart ini sangat berguna pada pada setiap perusahaan untuk menampilkan data statistik dari pertumbuhan database suatu perusahaan.

Oke langsung saja kita buat grafik / chart nya,

Berikut codenya,

<?php
 //you can change this data with your database
 $datas = array(
  array(
   'gender' => 'Laki-laki',
   'jumlah' => '123'
  ),
  array(
   'gender' => 'Perempuan',
   'jumlah' => '321'
  )
 );
?>
<html>
 <head>
  <title>Grafik | Chart</title>
  <script type="text/javascript" src="extension/jquery.min.js"></script>
  <script type="text/javascript" src="extension/highcharts.js"></script>
  <script type="text/javascript">
   $(function(){
     showChart();
   });

   function showChart()
   {
     var chart1; // globally available
     $(document).ready(function() {
       chart1 = new Highcharts.Chart({
          chart: {
             renderTo: 'chart',

Review - Custom server VS serverpilot

Hello everyone,

Kali ini codedoct akan mencoba sebuah experiment untuk membandingkan sebuah server yang dibuat dengan custom/manual konfigurasi dan server yang dibuat dan dimaintenance dengan menggunakan serverpilot.

Serverpilot merupakan sebuah aplikasi atau engine yang dibuat untuk mempermudah seorang developer dalam membuat, menjalankan, dan maintenance websitenya pada sebuah server.

Bagi anda yang tidak terlalu paham dengan OS server seperti Ubuntu, centOS dan sejenisnya, serverpilot tentu sangat membantu dalam hal mengkonfigurasi webserver anda, karena dengan serverpilot anda tidak perlu lagi mengkonfigurasi apapun seperti install php, enable site, konfigurasi HOST, dan lain-lain pada server, karena serverpilot sudah mengatur semuanya untuk anda.

Dengan konfigurasi yang serba otomatis lalu bagaimana dengan performa server yang diinstall dengan menggunakan serverpilot ini?

Berikut ringkasannya,

Dari data-data tersebut dapat kita lihat bahwa performa server yang dikonfigurasi dengan serverpilot cukup bagus dan tidak kalah dibandingkan dengan konfigurasi manual, tapi ada beberapa konfigurasi yang dapat kita lakukan dengan mudah pada server custom, tapi sangat sulit jika dikonfigurasikan pada serverpilot. Dan satu hal lagi, serverpilot ini tidak gratis hehehe..

Visual Basic - Membuat sistem (CRUD) Update dan Delete

Melanjutkan tutorial sebelumnya, tutorial kali ini kita akan melengkapi project kita sebelumnya dengan sistem CRUD yang lebih sempurna,

Pada tutorial kali ini kita akan melengkapi project sebelumnya dengan navigasi yang digunakan untuk mengupdate dan mendelete field database.

Oke langsung saja kita praktekan tutorialnya,

Pertama, tambahkan beberapa button baru sehingga tampak seperti ini,

Selanjutnya klik 2x button Prev dan isikan code berikut,

DataUserBindingSource.MovePrevious()

Kemudian klik 2x button Next dan isikan code berikut,

DataUserBindingSource.MoveNext()

Setelah itu klik 2x button Delete dan isikan code berikut,

DataUserBindingSource.RemoveCurrent()

Terakhir klik 2x button Close dan isikan code berikut,

Me.Close()

Full codenya terlihat seperti ini,

Public Class Form1

    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        'TODO: This line of code loads data into the 'Project_CRUDDataSet1.DataUser' table. You can move, or remove it, as needed.
        Me.DataUserTableAdapter.Fill(Me.Project_CRUDDataSet1.DataUser)
    End Sub

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        DataUserBindingSource.AddNew()
    End Sub

    Private Sub save_Click(sender As Object, e As EventArgs) Handles save.Click
        On Error GoTo SaveErr
        DataUserBindingSource.EndEdit()
        DataUserTableAdapter.Update(Project_CRUDDataSet1.DataUser)
        MessageBox.Show("Data was saved")
SaveErr:
        Exit Sub
    End Sub

    Private Sub Button3_Click(sender As Object, e As EventArgs) Handles Button3.Click
        DataUserBindingSource.MovePrevious()
    End Sub

    Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
        DataUserBindingSource.MoveNext()
    End Sub

    Private Sub Button4_Click(sender As Object, e As EventArgs) Handles Button4.Click
        DataUserBindingSource.RemoveCurrent()
    End Sub

    Private Sub Button5_Click(sender As Object, e As EventArgs) Handles Button5.Click
        Me.Close()
    End Sub
End Class

Saat di "Run" tampilannya akan tampak seperti ini,
