I tried to google it, and surprisingly found no result related... I wonder how can I use css to adjust the blinking cursor inside the search box with CSS? I adjusted the size of the search box, but seem the blinking cursor's size is still original small text size.
You cannot change the width of the caret (at least for now); But you can change the caret color for majority of modern browsers
https://developer.mozilla.org/en-US/docs/Web/CSS/caret-color
input {
caret-color: red;
caret-color: #ff0000;
caret-color: rgb(255, 0, 0);
caret-color: hsl(0, 97%, 50%);
}
