Default CSS Styling When Needed

With Oxygen and sometimes other instances there is a need for default styling to be set up.  Here is an ever growing stylesheet of some important style pieces. For instance when you set an image to align right or styling of a numbered list, you will need to add in the CSS.

.hide {
    display:none;
}

img.alignright {float:right; margin:0 0 1em 1em}
img.alignleft {float:left; margin:0 1em 1em 0}
img.aligncenter {display: block; margin-left: auto; margin-right: auto}
a img.alignright {float:right; margin:0 0 1em 1em}
a img.alignleft {float:left; margin:0 1em 1em 0}
a img.aligncenter {display: block; margin-left: auto; margin-right: auto}

ol > li > ol, ol > li > ol > li > ol {
    padding-bottom:0px !important;
}
ol > li > ol {
    padding-left:25px !important;
    list-style-type: lower-alpha !important;
}
li::marker {
    font-weight: bold;
}
ol > li > ol > li > ol {
    list-style-type: lower-roman !important;
}
