Add button inside input with rounded corners - html

Question

Id like to have a text input with a submit button inside the input and have the edges rounded using something like border-radius
Im using the css from the second answer in this question:
How to add button inside input
#form {
display:flex;
flex-direction:row;
border:1px solid grey;
padding:2px;
border-radius:50px; /* this is me trying to round edges of input*/
}
#input {
flex-grow:2;
border:none;
}
but when I add that border-radius the button no longer appears inside the input
how could I do it?

Answer 1

There are a couple of errors in your code. First, form and input are native tags, they don't need a hashtag in the css. If you assign an id to the form, that wil be your #id (i've given the form an id of 'form' for demo purposes.
You can give the form a border radius, but to make the buttons rounded without rounding the entire form, you need to add a border-radius to the input. You can assign a border-radius to all inputs by using input (general) or specify the type input[type=submit] in your css
Hope this helps
#form {
width: 60%;
display: flex;
flex-direction: row;
border: 1px solid grey;
padding: 2px;
border-radius: 50px; /*you can remove this to avoid rounded corners on the form*/
}
input {
flex-grow: 2;
border: none;
border-radius: 50px;
}
<form id="form">
<input type="text" placeholder="text" />
<input type="submit" value="Click here" />
</form>

Answer 2

How about something like this? The <form> is now just a flex container, and the border styles are actually applied to the input and the button.
#my-form {
display: flex;
flex-direction: row;
}
#my-form input,
#my-form button {
border-radius: 10px;
border: 1px solid grey;
padding: 2px;
}
#my-form input {
flex-grow: 2;
border-right-width: 0;
border-top-right-radius: 0;
border-bottom-right-radius: 0;
}
#my-form button {
background: teal;
color: white;
border-left-width: 0;
border-top-left-radius: 0;
border-bottom-left-radius: 0;
}
<form id="my-form">
<input type="text" />
<button type="submit">my button</button>
</form>

:root {
--border-width: 4px;
--border-radius: 10px;
--height: 40px;
}
input[type="text"],
input[type="submit"] {
transition: box-shadow .3s;
}
input[type="text"] {
width: 200px;
height: var(--height);
padding: 3px 60px 3px 5px;
border-radius: calc(var(--border-width, 1px) + var(--border-radius, 10px));
border-width: var(--border-width, 1px);
box-sizing: border-box;
border-color: blue;
border-style: solid;
}
input[type="text"]:hover,
input[type="text"]:focus {
outline: none;
box-shadow: 0px 0px 2px 3px blue;
}
input[type="submit"] {
transform: translateX(calc(-100% - var(--border-width, 1px)));
height: calc(var(--height) - 2 * var(--border-width));
background: blue;
color: white;
border: 0;
-webkit-appearance: none;
border-radius: 0 var(--border-radius, 10px) var(--border-radius, 10px) 0;
}
input[type="submit"]:hover,
input[type="submit"]:focus {
outline: none;
box-shadow: inset 0px 0px 2px 3px white;
}
<input type="text"><input type="submit">

Answer 4

You have to add a border and the border-radius to the input text element.
In the example you linked, it would be like this:
input[type="text"] {
width: 200px;
height: 20px;
padding-right: 50px;
border: 2px solid black;
border-radius: 30px;
}
EDIT:
If the border is supposed to go around both elements, then you could add this CSS to the button:
border: 3px solid black;
border-left: 0;
border-radius: 0 30px 30px 0;
