表单边框在内部元素周围创建空间

Question

I'm trying to create a simple bordered form that has a button and input of type="text" inside of it.

There is this spacing that appears that I cannot remove.

 main { display: flex; height: 100vh; width: 100vw; justify-content: center; align-items: center; } main form { display: flex; border: 2px solid green; } main form.btndep { display: block; padding: 10px; background: green; border: 0; box-shadow: none; outline: none; } main form input { border: 0; outline: none; box-shadow: none; text-align: right; padding-left: 5px; padding-right: 5px; }

 <main> <form class="deposit"> <button class="btndep">Deposit</button> <input type="text" placeholder="0.00€"> </form> </main>

Answer 1

I added a margin: 0 on your button and it seems to be working.

 main { display: flex; height: 100vh; width: 100vw; justify-content: center; align-items: center; } main form { display: flex; border: 2px solid green; /* Here is the line I added */ padding:0 } main form.btndep { display: block; padding: 10px; background: green; border: 0; box-shadow: none; outline: none; /* Here is the line I added */ margin:0 } main form input { border: 0; outline: none; box-shadow: none; text-align: right; padding-left: 5px; padding-right: 5px; }

 <main> <form class="deposit"> <button class="btndep">Deposit</button> <input type="text" placeholder="0.00€"> </form> </main>

there is a way around it; it seems... outline instead of border
