I just realised that if you do display the other resource icons you will probably want to change their colour to match the link text.
The below will allow you to play with all the link colours if you wish, just by changing the colour values.
Again, red is probably not the best choice for the internal links but it certainly makes them stand out when trying the CSS and, again, I have not had the time to ensure that these changes do not cause problems elsewhere in Joplin’s Markdown renderer…
a {
color: #0000CD; /* set general link colour - includes TOC links*/
}
a[data-resource-id] {
color: #FF0000; /* change the colour of INTERNAL links */
}
.resource-icon.fa-joplin {
display: none; /* do not display the Joplin resource icon */
}
.resource-icon {
background-color: #FF0000; /* change other resource link icons to the same as the internal link colour */
}
Please remember that once you start CSS “modding” of Joplin it is up to you to maintain. This is because a later version of Joplin may be released that implements a different element/class naming scheme and all or some of the above may stop working…
