sidebar subcatagory second line won't indent wordpress

Some of the subcategories (pages) on my sidebar are too long and they wrap into the second line but they don’t automatically indent inline with the first line. See website: https://www.naturalsystemsutilities.com/

Here is my style css code. What should I fix in this code to have the second line indent:

/*
Theme Name: NSU
*/

/* main elements */

#header ul li{text-transform:uppercase;}
.list li li li a , .list li li li .active a {

}
#commentform fieldset{border:none;}
#comments li {list-style:none;}
#commentform input{ width:300px; margin: 5px 0 5px 0;}
#commentform #submit{ width:150px;}
.navigation .next{float:right;}

.articless {
    float: left;
    padding: 29px 10px 0 3px;

}
.articless img {
    float: left;
    margin: 0 10px 0 0;
}
.mark{ margin: 0 0 28px;}
#content .mark p{margin:0;
 display: inline;
}

#content .gallery img {
      border: 1px solid #000000 !important;

ul.gallery{  width: 694px; }

	height: auto; /* Override height to match resized width for correct aspect ratio. */
}
