Hey @anhanhoi,
Since you’re using Pro. That is possible. Here are the steps to replicate that.
1. Use our theme’s Page Background Image feature. If you use 2 or more images, this becomes a slider background. The effect is similar to your sample site where an image fades to another image.

2. Use a Blank No Container | Header Footer Page template. For more details about Page templates, please see https://theme.co/apex/forum/t/meta-options-pages/144
3. Create a Pro custom header for your page. The header should have 2 bars. The top bar’s height should be 80vh and the bottom one that will contain the menu should be 20vh. I believe you get that the height of both bars combined is 100vh and that is the full height of the screen.
Below is a video demonstrating the steps. You can lower the play speed and pause and play the video to follow along.
Hope that helps.
