Select and input form boxes won't line up using flex-CodePudding

On my form I have title, first name and last name on the top line. I am using flex to give the title 20% width and the first and last name 80% between them. Firstly, the title box isn't ever fully in line with the first and last names boxes, it is very minimally taller. Secondly, when my validation error messages show the title box completely moves out of place.

I have tried to research the different styling rules of select boxes but can't seem to find anything that would help. I could wrap all three boxes in one container but then I would have to give them all equal widths?

This is what happens when I submit the select box moves out of place:

     color: white;
     padding: 1rem;
     width: calc(100%   3rem);
     margin: 0;
     font-size: 1.3rem;
     text-align: center;
     box-sizing: border-box;
}

Please look into the following snippet. You need to style .titles class with the given below properties:

.titles {
 display: flex;
 flex-direction: column;
 justify-content: flex-start;
 width: 20%;
 align-items: flex-start;
}

Hopefully, This solves your problem.

You try adding some margin-bottom to it so it moves up on its own.
