Unable to customize line spacing 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?
