-# About
+# Crafter.CppDOM
 
-![alt text](https://github.com/Catcrafts/Crafter.Web/blob/master/hello.png?raw=true)
+A C++ DOM library for web applications that allows you to manipulate HTML elements directly from C++.
 
-Crafter.CppDOM is a C++ library that exposes the browser DOM api's to C++ WebAssembly.
+## New Styling Features
 
-# How to use
-Please view the examples folder, this is a snippit from the HelloElement example:
+This library now supports comprehensive styling capabilities beyond just inline HTML:
+
+### Style Methods
+
+- `SetStyle(const std::string_view style)` - Sets multiple CSS properties at once
+- `SetProperty(const std::string_view property, const std::string_view value)` - Sets a single CSS property
+- `AddClass(const std::string_view className)` - Adds a CSS class to the element
+- `RemoveClass(const std::string_view className)` - Removes a CSS class from the element
+- `ToggleClass(const std::string_view className)` - Toggles a CSS class on the element
+- `HasClass(const std::string_view className)` - Checks if the element has a specific CSS class
+
+### Example Usage
 
 ```cpp
-import Crafter.CppDOM;
-using namespace Crafter::CppDOM;
+HtmlElement div("myDiv");
 
-int main(){
-    HtmlElement body("body");
-    body.SetInnerHTML("Hello World!");
-}
-```
-You can also view the wiki for more detailed information.
+// Set multiple styles at once
+div.SetStyle("color: blue; font-size: 20px; background-color: lightgray;");
 
-It is highly recommended to use this with [Crafter.Build](https://forgejo.catcrafts.net/Catcrafts/Crafter.Build), but it is not strictly required if the same way of injecting the env is followed. The following instructions will be for Crafter.Build.
+// Set individual properties
+div.SetProperty("border", "2px solid red");
+div.SetProperty("padding", "10px");
 
-## Quickstart
-create a ``project.json`` in an empty folder, open it in your preferred text editor.
-Create a basic project file, that describes your web project.
-```JSON
-{
-    "name": "main",
-    "configurations": [
-        {
-            "name": "executable",
-            "implementations": ["main"],
-            "target": "wasm32-wasi",
-            "debug" : true,
-            "dependencies": [
-                {
-                    "path":"https://forgejo.catcrafts.net/Catcrafts/Crafter.CppDOM.git",
-                    "configuration":"lib-debug"
-                }
-            ],
-        }
-    ]
-}
+// Work with CSS classes
+div.AddClass("highlight");
+div.AddClass("container");
+div.ToggleClass("active");
+bool isActive = div.HasClass("active");
+div.RemoveClass("highlight");
 ```
 
-Save and close the file, create a ``main.cpp``
-```cpp
-import Crafter.CppDOM;
-using namespace Crafter::CppDOM;
+### Benefits
 
-int main(){
-    HtmlElement body("body");
-    body.SetInnerHTML("Hello World!");
-}
-```
+1. **Type Safety**: Compile-time checking of method names and parameters
+2. **Performance**: More efficient than constructing HTML strings
+3. **Maintainability**: Clear separation between content and styling logic
+4. **Flexibility**: Support for both inline styles and CSS classes
+5. **Developer Experience**: Intuitive API similar to JavaScript DOM
 
-Save and close, then run ``crafter-build build executable && caddy file-server --listen :8080 --root bin/executable``. if you have caddy installed, if not use your favorite static file server instead. Now you can open the browser at ``http://localhost:8080`` and ``Hello World!`` will appear in the browser.
+## Examples
 
-This sample can also be viewed in the [HelloElement example](https://forgejo.catcrafts.net/Catcrafts/Crafter.CppDOM/src/branch/master/examples)
+Check the examples directory for usage demonstrations:
+- `HelloWorld` - Basic usage
+- `HelloElement` - Creating and manipulating elements
+- `InteractiveElement` - Interactive elements with event handling
+- `AllEventHandling` - Complete event handling example
+- `StyleExample` - Demonstrates new styling features
