I just can't realize why first child has white space right after parent's "border". What is my mistake?
.content {
font-size: 22px;
}
.content__row {
height: 150px;
}
.content__column_half {
width: 49%;
height: 100%;
display: inline-block;
box-sizing: border-box;
padding-top: 30px;
padding-bottom: 30px;
border-bottom: 1px dotted #000000;
background-color: graytext;
}
