CSS is working yes, what happens is that simply Google is carrying a "lighter" and "older" version of your site, this is because either it does not recognize your browser as a modern browser, or thinks it is Internet Explorer.

The component WebBrowser (https://docs.microsoft.com/en-us/dotnet/api/system.windows.forms.webbrowser?view=netframework-4.8) will use the functionality of the user’s operating system, through Activex, in case it depends on the version of the IE that the customer has installed, will be the support that will have your component, so if you are going to load a website designed with support for old browsers, will work perfectly, otherwise it is impossible.

If you want a better engine/engine, like the same one used in Google Chrome, called Chromium, you can try this project:

• https://github.com/cefsharp/CefSharp

If using Winforms, install via Nuget:

• https://www.nuget.org/packages/CefSharp.WinForms/

An example from Cefsharp (https://ourcodeworld.com/articles/read/173/how-to-use-cefsharp-chromium-embedded-framework-csharp-in-a-winforms-application):

public partial class Form1 : Form
{
    public ChromiumWebBrowser chromeBrowser;

    public Form1()
    {
        InitializeComponent();

        // deve ser chamado depois de InitializeComponent
        InitializeChromium();
    }

    private void Form1_Load(object sender, EventArgs e)
    {

    }

    public void InitializeChromium()
    {
        CefSettings settings = new CefSettings();

        // Inicia as configurações que você forneceu
        Cef.Initialize(settings);

        // Cria o componente
        chromeBrowser = new ChromiumWebBrowser("https://www.google.com");

        // Adiciona para o form (ajuste aqui)
        this.Controls.Add(chromeBrowser);
        chromeBrowser.Dock = DockStyle.Fill;
    }

    private void Form1_FormClosing(object sender, FormClosingEventArgs e)
    {
        //Finaliza "quando fechar"
        Cef.Shutdown();
    }        
}
