Creating your own theme
When working with themes, there are some important things to know. First of all, there is the theme export SQL file in which all templates of the theme are included. Secondly, there are the images that belong to your theme. And thirdly, there are the .css
files. CSS is an abbreviation of Cascading Style Sheet and describes the style of the elements in a web page. For example, the font of the text or the color of the background. In the stylesheet there are also references to images. It is important that the references in these files are correct, otherwise you will see no style at all, just plain text.
When you want to create your own theme you can do two things: start from scratch or copy an existing theme and adapt it. Starting from scratch is more work as you have to create all the templates as well. Copying and modifying an existing theme costs less time but if you have to change a lot in order to get the desired layout, you might as well start from scratch.
