Working with Bootstrap

Before you start acquaintance with Bootstrap, download it freely. After downloading and subsequent unpacking, the user will receive three folders that contain styles, scripts and iconic fonts. All this is Bootstrap. You can open a modal window after you create a folder with the name of the framework. In it, you need to create an empty "ndex.html" file. In the downloaded software, select the entire folder "fonts" and the style "bookstrap.css" from the corresponding folder. Do not forget also about the script "bootstrap.js". Create an existing folder with the same name as "css", put "bootstrap.min.css" in it. Make another "css" with an empty "style.css" file. It will be required to add your own styles.

When everything necessary is created, further work will be done only with "ndex.html". If you do not want to write the codes manually, refer to the finished html-skeleton of the document. Copy and paste the code into a file. In the created skeleton styles, a library and a script will be connected. Before the body tag, do not forget to connect the library "jQuery", and after - the script "js".

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 individual wrap. The basement and the header of the site should be 100% wide, the main part and side columns may be smaller.

The Bootstrap grid is needed just to set the blocks to the required width. The grid functions by using a table that has columns and rows. A grid can be made inside another grid unlimited times. If parts of the site are made with it, there is no need to write adaptive queries yourself. In addition to the grid, the modal window contains many additional components (menus, tables, tabs, hints).

Errors

Sometimes, several modal Bootstrap windows open at the same time can lead to an error. This is possible if Windows is not able to correctly load a file such as html. The presence of an error indicates that the file has been corrupted by malicious software or a virus. Most often, errors associated with the Bootstrap file occur during the loading of programs, the computer, or after performing any actions. The most common ones are those associated with the modal window: "Error in file", "Missing file", "Not found", "Failed to load", "Failed to register", "Failed to execute and load". They can appear when the user installs the program or is already running, as well as when the computer is turned on and off. It is important to closely monitor the occurrence of errors, as this helps to correctly eliminate the cause of their occurrence in Bootstrap. The modal window does not work sometimes due to an invalid call, which does not depend on internal errors.
