In this tutorial we explain how to open a css file, and how to edit it whitout write code.

First of all we need ArduoCss editor. It is free and you can download it from this site. In the previous tutorial "How to install ArduoCss editor" we teach how to download and install it.

We can run it by the desktop icon or trough the windows menu start >> programs >> ArduoCss  and clicking on ArduoCSS icon.

This is the startup form of ArduoCss. You can open a new css file by standard menu file >> open or clicking in the yellow "Open file" link in the startupContent.

After that a file open dialog will appear. You have to choose the right file and click "Open".

The css document will be loaded on a new tab sheet. The application allow to manage multiple style sheet: each one has its tab sheet.

note:

Yoou can work in "visual mode" or in "text mode". In "visual mode" you can build a css without write css code, all the css code is managed by the application.

Work in managed mode prevent errors and let the designer to focus on the styles without waste times on writing code. By the way lot of graphic designer think that a textual editoe is more efficent than a managed one.

So each document can be edit in both way. You can swith from one modality to another by clicking on the buttons belove the node list. By now, We assume to work in "visual mode".

As said above, each css document as a tab sheet. You edit always the selected one. In the center of the window you will find the list of  the css styles. By single click you choose the style.

The right panel allow you to edit the selected node. In this panel there are all the css properies. For each properties you can assign a value. Most of property types (colors,fonts, size etc..) as a specific editor.

For example we will try to edit the "body" style changin the "border-top-color" property. We have to:

1. Single left click on the node. (the style expands and all appear)
2. By the rigth panel, we find the property and click on the button near the property.A littel color pciker will appear.
3. By single click we select the desidred color.

After each change to the document, the "preview panel" will be updated. You can check the element styles, before the css will be applied to the html document.

In the last screenshot I turned to "text mode" to see the generated code.

An Alternative way to edit a css style is by double-clik on the style. After a double click a edit window appear. On this windos you find a tab sheet for each properties category,

on each tab sheet you can set the properties of this category.

First of all download and install ArduoFileSplitter. If you find some problems during installation, please contact us.

Suppose that we nee to split a big file called "bigfile.zip" into smaller pieces no more big than 100KB.

The first step is to open the application. To do thi start menu > Programs > ArduoFileSplitter > and click into ArduoFilesplitter icon. This may vary from pc to pc.

Only for who download the portable version:

If you have downloaded the portable version, you need to extract the executable file from the zip archive. You can use the freeware 7zip op winrar. After that you can run the application.

Once the application run you got a window like this:

Now we need to:

1. Select the big file
2. Select the output folder
3. Run the split process

Select the big file

click into the "Select File..." button. A Open File selector dialog will appear. Through this you can choose the desidred file, in this sample the "bigfilke.zip" on my pc.

Select the output folder and file size

The choosed file will be fragmented into smaller pieces and wiil be saved into a folder. So We choose the output folder clicking into "Select output folder". 

We have to say how much bigger must be each cunk! So we put 100 into the site textbox and choose KB as measurement unit. If you wnato to use default sizes (i.e. CD ROM size or DVD Size) you find them as pre configured.

Select the big file

In the end, the easier task: we nee only to click the "Split" file. The process could take some minute, but you can check the state of the work through the progress bar.

Wen the progress finished, a popup alert you.

So we can open the selected folder:

This is the foldere used in my example, there is:

1. the original file
2. A set of file of 100 KB
3. The checksum file

The original file has been splitted into 16 pieces each of 100KB and a md5 checksum file has been product.

This file i very important beacuse contains a md5 checksum for each chunk and the checksum for the whole file. When you will send thoose chunks to someone, it could happen that some chunk will be corrupted during internet transfert. So the receiver ca check the integrity of each file with ArduoFileSplitter. If some chunk is not good, it ca be re sended. After the whole file have been rebuild with ArduoFileSplitter, you can check the integrity of the whole file. Now if there are an error,it dependes only by the receiver, because each cunks was good. You can discover how to rebuild a file, given a set of chunk, in the next tutorial.

In this section will be store all tutorials and help information.
