when I focus my input with
border-radius
border radius
input[type="text"]{
border: 1px solid red;
border-radius:10px;
}
<input type="text">
The blue rectangle is referenced as outline
you can hide it via the outline: none
rule
input[type="text"]{
border: 1px solid red;
border-radius:10px;
}
input[type="text"]:focus{
outline: none

<input type="text">
Of course you can style it.. See this w3c school post to see applicable rules.
