I looked at that, and the code has:
<div style="color: #000; background-color: #fff; font-family: arial, helvetica, sans-serif; font-size: 10pt;" id="yiv2575389172yui_3_16_0_1_1405658232141_11311">
<p style="text-align: left;"><a href="https://thecreativecanvass.com/wp-content/uploads/2014/06/Muffin-and-mummy.jpg"><img width="213" height="284" alt="Muffin and mummy" src="https://thecreativecanvass.com/wp-content/uploads/2014/06/Muffin-and-mummy-225x300.jpg" class="alignleft wp-image-621"></a>Hello and welcome to the Creative Canvass.</p>
Given that the style is generated inline with that DIV tag and is not in a CSS file, tells me it’s generated by the theme or some plugin and can be changed with it. Might try putting the following into the theme’s CSS file:
#yiv2575389172yui_3_16_0_1_1405658232141_11311 {
color: #000 !important;
background-color: #fff !important;
font-family: arial, helvetica, sans-serif !important;
font-size: 10pt !important;
}
Change the above values to what you want. Well only if that seemingly random ID stays the same though.
Hmmm.. or you might edit the About page’s HTML and add your own style to the paragraph tags in the post itself.
