Photo size in the slider, and no text in the widget Recent Post

Hello lucy211,

about your problem on slider the theme crop a image for the slide.. in your case I believe the small images was articles that was added before the theme was used.. in this case you can remove the featured image on those then try to re upload it.. so the theme will crop the correct image size..

and on sidebar recent post sorry i may miss looked that part please try to add this line of css on style.css

.flat-white-recent-post .post-desc-container {
position: inherit;
max-width: 260px;
margin: auto;
background: rgba(0, 0, 0, .5);
padding: 15px;
}
.post-thumb-container .post-desc-container {
position: absolute;
bottom: 0;
width: 100%;
left: 0;
}

thanks
