Can't Customize the Line-height in Sahifa theme :(

Hi, I am trying to change the line-height in the CSS file but it does not work at all. ??

I changed `.entry {
word-wrap: break-word;
line-height: 22px;
}`

to

.entry {
word-wrap: break-word;
line-height: 30px;
}

but it doesn’t work at all and the spacing size is still 22px while I look in inspect element.

Kindly help me where I am wrong?
