WebView Show only part of Website/ hide a part of the website

I am trying to show only part of the website. I am trying to hide the slideshow. For some reason, my code doesn't work and it still shows the whole page. I searched the whole web but couldn't find an answer that worked out for me. I am still a beginner, so sorry if I make some dumb mistakes:) Thank you in advance!!

package com.example.myapplication;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;

public class MainActivity extends AppCompatActivity {

 webview.getSettings().setJavaScriptEnabled(true);
        webview.setWebChromeClient(new WebChromeClient());
        webview.setWebViewClient(new WebViewClient(){
        @Override
        public void onPageFinished(WebView view, String url) {
        super.onPageFinished(view, url);
        view.evaluateJavascript("document.getElementById('main-carousel2').style.display='none';", new ValueCallback<String>() {
            @Override
            public void onReceiveValue(String value) {
                Log.e(TAG,value);
            }
        });
    }
});
    webview.loadUrl("http://www.eventster.it");
}

here is what you need to hide the section:

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.webkit.ValueCallback;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebViewClient;

public class MainActivity extends AppCompatActivity {

    private static final String TAG = MainActivity.class.getSimpleName();
    WebView webview;
    final String URL = "http://www.eventster.it";
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        webview = findViewById(R.id.webview);
        webview.getSettings().setJavaScriptEnabled(true);
        webview.setWebChromeClient(new WebChromeClient());
        webview.setWebViewClient(new WebViewClient(){
            @Override
            public void onPageFinished(WebView view, String url) {
                super.onPageFinished(view, url);
                view.evaluateJavascript("document.getElementById('main-carousel2').style.display='none';", new ValueCallback<String>() {
                    @Override
                    public void onReceiveValue(String value) {
                        Log.e(TAG,value);
                    }
                });
            }
        });
        webview.loadUrl(URL);
    }
}

The thing is you are asking webview to hide a content which isn't loaded yet i.e you need to wait until the webView finish loading the full page so that you can hide the content.
