Yes there is a way.
You need to learn how to use your browser inspector, it will show you how your html and css are working.
For tutorials on html + css etc: https://www.w3schools.com/
You may do better asking this question at the support forum for your theme.
thanks. i will give it a try
just checked, no support forum for the Tesseract theme
Well with no theme support, that leaves you with your browser inspector and w3school and other tutorials, how are they going ?
Maybe you should think about changing theme.
I was thinking the same, any suggestions to a good theme for a photography site?
I have no specific suggestion. I would suggest you identify a gallery plugin that you like. Then you are free to use any theme you find attractive. Finding a theme that both looks good and offers a good gallery feature really limits your options.
In selecting either plugins or themes, you should seek modules that are regularly maintained and actively supported. Popularity is a factor only because there would more likely be a larger support community to draw upon.
