Work with Bootstrap
Before you start getting to know Bootstrap, download it freely. After downloading and subsequent unpacking, the user will receive three folders that contain styles, scripts and icon fonts. All this is Bootstrap. You can open a modal window after creating a folder with the name of the framework. In it you need to create an empty file "ndex.html". In the downloaded software, completely select the “fonts” folder and the “bookstrap.css” style from the corresponding folder. Do not forget the “bootstrap.js” script as well. Create a folder similar to the name “css” in an existing folder, place “bootstrap.min.css” in it. Make another “css” with an empty “style.css” file. You will need it to add your own styles.
When everything you need is created, further work will only be done with "ndex.html". If you do not want to write codes manually, refer to the ready-made html-skeleton of the document. Copy and paste the code into the file. In the created skeleton, styles, library and script will be connected. Before the body tag, do not forget to connect the jQuery library, and after that - the js script.
Grid
The Bootstrap modal window is used to create a classic site layout. It consists of a cap, a main part, a side column and a basement. In order for everything to be displayed correctly, it is necessary to calculate the width of each element in percent with an individual flow. The basement and the heading of the site should be 100% wide, the main part and side columns may be smaller.
The Bootstrap grid is needed just to give the blocks the required width. The functioning of the grid occurs using a table that has columns and rows. A grid can be made inside another grid an unlimited number of times. If parts of the site are made with its help, there is no need to write adaptive queries yourself. In addition to the grid, the modal window contains many additional components (menus, tables, tabs, tooltips).
Mistakes
Sometimes multiple Bootstrap modal windows open at the same time can lead to an error. This is possible if Windows is not able to correctly load a file of type html. The presence of an error indicates that the file was infected with malware or a virus. Most often, errors associated with the Bootstrap file occur during program, computer startup, or after some action. The most common ones are those associated with the modal window: “Error in file”, “Missing file”, “Not found”, “Failed to load”, “Failed to register”, “Runtime and loading error”. They can appear when the user installs the program or it is already running, as well as when the computer is turned on and off. It is important to carefully monitor the occurrence of errors, as this helps to correctly resolve the cause of their occurrence in Bootstrap. The modal window sometimes does not work due to an incorrect call, which does not depend on internal errors.
