Hello Monica,
Sorry for late reply to this,
I have tried to inspect in your site, you can applied the CSS code below into your template css file from
JoomlaFolder/templates/rox_doom/css/template.css
First you have to remove this line code
.blog-meta-bottom .blog-more {
font-size: 20px;
color: #6f2b6c !important;
text-decoration: underline; //REMOVE THIS LINE CODE
}
After that add this few code at your bottom
.blog-meta-bottom .blog-more a
{
text-decoration: underline
}
.blog-meta-bottom .blog-more a:hover
{
text-decoration: none;
}
#ezblog-menu .blog-navi li.toolbar-item > form {
margin: 0 !important;
}
#ezblog-body .blog-post .blog-title, #ezblog-body .blog-post .blog-title a {
font-size: 30px !important;
}
#ezblog-menu .blog-navi li.toolbar-item > form input.input {
width: 300px !important;
}
Then clear your everything cache and reload your file again and see how it goes.
