How to prevent input from cutting tails of the letters without changing the height? - css

Question

I'm trying to achieve an input field with an underline. As it is visually more appealing to me, I'm trying to make underline as close as possible to the font. I did achieve the closeness, but now, input field cuts tail parts of the letters with tails. Is there a possible workaround for this? Can I cancel input's this behaviour with something like "overflow: visible"? Or may I draw a fake line over the input field, instead of using border-bottom? Thanks in advance.
In short, I'm trying to make text get through the bottom line.
Here is a screenshoot about the problem.
Here is my current class:
.kk_input {
border: 0;
border-bottom: 1px solid #000;
outline: none;
font-size: 20px;
height: 20px;
margin-top: 5px;
}

Answer 1

Without seeing the rest of your markup, this should give you an idea enough to go off of.
.kk_input {
border: 0;
outline: none;
font-size: 20px;
}
div {
position: relative;
}
div:after {
position: absolute;
content: "";
bottom: 4px;
left: 0;
height: 1px;
width: 100%;
background-color: black;
}
<div>
<input class="kk_input" type="text">
</div>

You can use more than one box-shadow to create this effect.
.so49204829_input{
line-height: 20px;
font-size: 20px;
padding: 8px 4px;
box-shadow: inset 0 -11px 0 #fff, inset 0 -12px 0 #000;
}
<input type="text" class="so49204829_input">
& here's another approach using a second element. Unfortunately, you can't add an :after pseudo-element to input elements (at the time of posting).
.so49204829_input {
line-height: 20px;
font-size: 20px;
padding: 8px 4px;
width: 200px;
display:block;
}
.so49204829_input_accent {
margin-top: -14px;
height: 1px;
width: 208px;
background-color: #000;
pointer-events: none; /* this makes sure click events aren't intercepted by the accent-line element */
}
<input type="text" class="so49204829_input"><div class="so49204829_input_accent"></div>
