Fibo Golden Ratio

The plugin is designed to overlay the Golden section grid on the page during the preview when editing.
Allows you to visually assess whether the page element sizes and its position correspond to the Golden ratio.
You can change the size of the grid and move it around the page using the mouse and its wheel.
There are grid modes: lines, circles, squares, and the Fibonacci spiral. There are also tooltips for the control buttons. All modes can be enabled and disabled using the checkboxes on the options page.
The data table of the appropriate width and height of an element is also processed. You can hover the cursor over the data in the table. The grid lines corresponding to the data will be highlighted.
A set of control buttons allows you to hide and display the grid and data table, change the grid size proportionally, invert colors, make lines dotted, and rotate the displayed spiral and circles.
There is also a button for General enabling and disabling plugin elements on the screen.
On the option page you can choose colors of lines, remove unnecessary elements of the grid, change the line width and opacity.
There is also a checkbox that allows you to completely enable or disable the plugin. So, there is no need to deactivate the plugin when it is not needed.
The plugin does not affect the appearance and html code of the page when its publishing.
