}

input[type="text"]:hover, input[type="text"]:focus{
    border: 1px solid #cccccc;
    border-radius: 8px;
}

/*Style input text boxes*/
input[type='text'][name='Worksheet-Name']{
    font-size: 36px;
    margin-top: 20px;
    margin-left: 15px;
}

input[type='text'][name='Worksheet-Problem']{
    font-size: 20px;
}

/*Change placeholder*/
input[type='text'][name='Worksheet-Name']::-webkit-input-placeholder { /* Chrome/Opera/Safari */
    font-weight: 500; 
    font-size: 36px;
}
input[type='text'][name='Worksheet-Name']::-moz-placeholder { /* Firefox 19+ */

}

Answer 1

Guys sometimes proposed solutions don't work with placeholders, here is more powerful approach:

input::placeholder {
  overflow: visible;
}

Answer 2

You can reduce the bottom padding and/or the font size and that will fix your overflow issue.

input[type='text'][name='Worksheet-Name']{
    font-size: 35px;//instead of 36
    margin-top: 20px;
    margin-left: 15px;
}

or

.input-lg {
    height: 46px;
    padding: 10px 16px 0;//change here to have 0
    font-size: 18px;
    line-height: 1.33333;
    border-radius: 6px;
}
