The Ren'Py visual novel engine .

Ren'Py is a visual novel engine – used by thousands of creators from around the world – that helps you use words, images, and sounds to tell interactive stories that run on computers and mobile devices. These can be both visual novels and life simulation games. The easy to learn script language allows anyone to efficiently write large visual novels, while its Python scripting is enough for complex simulation games.

MAVO : Create webpages with HTML and CSS .

A start intro into MAVO can be found here.
The MAVO is a simple way to create good design and graphics for your website.
The development team tells us: What if I told you, that you can do these things (and more!), just with HTML and CSS? No programming code to write, no servers to manage.
A demo page shows us how good is this system, see here.

New codepen example - modal window.

In user interface design for computer applications, a modal window is a graphical control element subordinate to an application's main window. It creates a mode that disables the main window, but keeps it visible with the modal window as a child window in front of it.
This is my example with a modal window created on codepen website.
The example is very simple.
The html5 source code is created with classes and id's.
The css file make all style for this tags.
The javascript use all of this to open the modal window, use click to close the window.
The Cancel and Add buttons not work with the java script.

Create a shadow text effect with HTML5 and CSS .

This tutorial is simple because I used HTML5 and CSS.
The CSS source code is simple (see: font-size:13px or you can use any size, colors , background).
I used my jsfiddle account to test and run it.
Create a project into jsfiddle editor and add this source code.
Into HTML5 area the source code can start with your text into div tag and named class font_001.
You can add span tag to have display block CSS style.
Into CSS area the source code is this:

@import url(https://fonts.googleapis.com/css?family=Work+Sans);

body {
  line-height: 2.5;
  margin: 0;
  background: #1F4C6F;
  font-family: 'Work Sans' sans-serif;font-size:13px;
}

.font_001 {
  max-width: 50%;
  margin: 0 auto;
}

h1 {
  color: #fff;
  font-weight: 810;
  padding-top: 4rem;
  margin: 0;
  text-transform: uppercase;
  font-size: 3em;
  line-height: 1.8;
  color: #3C6FB0;
  text-shadow: 20px 5px 30px rgba(0,0,0,.2), -30px 10px 30px rgba(0,0,0,.1), 
-40px 10px 30px rgba(0,0,0,.1), -3px 2px 5px #1F4C6F, 3px -2px 5px #3C6FB0;
}

h1 span {
  display: block;
  
}

The EaselJS java script libraries.

The team development teel us:
A suite of modular libraries and tools which work together or independently to enable rich interactive content on open web technologies via HTML5.

• EASELJS - working with the HTML5 Canvas;
• TWEENJS - for tweening and animating HTML5 and JavaScript properties;
• SOUNDJS -  work with audio on the web;
• PRELOADJS - manage and co-ordinate the loading of assets and data;

These javascript libraries are used and used to create web content for all modern desktop and mobile browsers.
To include the EaselJS libraries in your project by linking to the CreateJS CDN it is necessary to link them with script tag :

src="https://code.createjs.com/easeljs-0.8.2.min.js"

The official site offers readers only some modest demo about the capabilities of these libraries for creating web content.

Create 3D text with HTML 5 .

This is the result of this tutorial:

The example is simple and use two ways to draw text.
First use a function how make the text by using index variable to put on canvas same text.
The next use function strokeText to add to canvas the text.
The onload function is used to put on canvas all you need to see.
This is the source code for java script I used into head HTML5 tag :
window.onload = function(){
 var canvas = document.getElementById("3dCanvas");
 var canvasWidth = canvas.width;
 var canvasHeight = canvas.height;
 var ctx = canvas.getContext("2d");
 ctx.font = "20pt Verdana";
 ctx.fillStyle = "black";
 ctx.textAlign = "center";
 // first
 drawTextInCanvas(ctx , "graphic-3d.blogspot.com", canvasWidth/2, canvasHeight/2, 4);
 // the next
 ctx.strokeText('... read this website !', 150, 150);
};

function drawTextInCanvas(ctx, mytext, wdth, hght, dpth){
 var index;
 for (index = 0; index < dpth; index++) {
  ctx.fillText(mytext, wdth - index, hght - index);
 }

 // shadow casting in bottom layers
 ctx.fillStyle = "#30F30F";
 ctx.shadowColor = "black";
 ctx.shadowBlur = 6;
 ctx.shadowOffsetX = dpth+ 2;
 ctx.shadowOffsetY = dpth+ 2;
 ctx.fillText(mytext, wdth - index, hght - index);

}
Then add the canvas tag into body tag with this :
id="3dCanvas" width="400" height="200" style="border:1px solid black;"
