I am very curious how to make the equation and the blank space combined become one. This is also like in sololearn but much more complicated because the equation is very hard. I have learnt Java, PHP, html, and now Python. But I haven't mastered them enough. Please help me. Please don't angry at me to ask a question like this. I really need your help.

//it can be fixed using width and height in vh like
Height:100vh; it will take full height on vertical height, other like pixel, % take only exact values

//About your situation i can only say create your 3-4 projects, and push your self forward, Doing real project will help to overcome this type of bugs

Answer 2

I am sorry maybe the link couldn't be opened via handphone but it will work via chrome in laptop. But my problem is I don't know how to create a blank space like in Sololearn but with more advance mathematical equation such as differensial. I want to create uncomplete equation and the user should be the one who complete the equation in my apps.
