I studied HTML & CSS, Java, and JavaScript at Progate and decided to make something, but I was frustrated because there were too many things I didn't understand. What should I do specifically?

I think HTML5 and CSS3 are good choices, but the actual service is HTML5 + CSS3 + Python and C ++ for speeding up the server side (C ++ is outsourced to the team or someone who can do it within the team if there is a budget). Go language. Or HTML5 + CSS3 + Go language (including server side). It seems that the composition is realistic and good. It is a configuration that also has a C10K problem. JAVA is too difficult. The learning hurdle is high. I'm always interested in profitable businesses, so I always watch TV's Gatch Remanday, buy and sell real estate, rent, employment change information services such as recruitment, AI agency sales services, etc. I think it is an easy example, so I hope you can use it as a reference for having goals and objectives.

プロゲートでHTML&CSS、Java、JavaScriptを勉強し何か作ろうと思いましたが分からないことが多すぎて挫折しました。具体的に何をどうすればよいのでしょうか？

実際のサービスは、HTML５＋CSS３＋　Pythonとサーバーサイドは高速化の為にC++（C++はチームもしくは予算があれば外注かチーム内の出来る人に任せる）かGo言語。もしくは、HTML５　＋　CSS3　＋　Go言語（サーバーサイドを含めて）。と言う構成も現実的で良いようです。C10K問題も出来ている構成としてです。JAVAは難しすぎます。学習のハードルが高いですよ。それと儲かるビジネスに日頃から興味を持ち、TVのガッチリマンデーは欠かさず見る様にしたり、不動産の売買や賃貸、リクルートの様な就職転職情報サービスやAI代行営業サービスなどは、儲けやすくて二番煎じがしやすい典型だと思いますので、目標や目的を持つ事の参考にして頂ければと思います。
