CSS Rotated Text With Background Shows Some Background-issues

I am using CSS to slightly rotate Text. The text is black on a white background, but because of the rotation part of the background has some little transparent lines going through

Solution 1:

Add a small inset box-shadow to avoid this issue (seems to do the job only on Chrome)

.item-heading { 
    /*Black text on white background*/
    box-shadow:
      0 0 0 5px #fff,
      0 0 0 2px #fff inset;
    padding: 0;
    background: #fff;
    line-height: 2 !important;
    display: inline;
    color: #000;
    text-shadow: none;
}

.caption h3 {
    /*Rotate Text*/
    transform: rotate(-3deg);
    margin-bottom:15px;
}

body {
 background:pink;
}

<div class="caption caption-large">                                     
<h3><a href="http://www.fair-fashion-magazin.de/2019/07/03/das-nachhaltige-mode-label-people-tree/" class="item-heading">Fashion zum Verlieben:<br> Das Fair Fashion Label People Tree</a></h3>
</div

Another idea is to consider border and rely on box-decoration-break (pay attention to the support: https://caniuse.com/#feat=css-boxdecorationbreak)

.item-heading { 
    /*Black text on white background*/
    border:5px solid #fff;
    padding: 0;
    background: #fff;
    line-height: 2 !important;
    display: inline;
    color: #000;
    text-shadow: none; 
    -webkit-box-decoration-break: clone;
     box-decoration-break: clone; 
}

.caption h3 {
    /*Rotate Text*/
    transform: rotate(-3deg);
    margin-bottom:15px;
}

body {
 background:pink;
}

<div class="caption caption-large">
