Modal box structure:
The default Bootstrap modal box is as follows:
Trigger modal box:
You can use a link or button to trigger a modal box. The marker for the trigger element may look like this:
<a href="http://miracleart.cn/link/93ac0c50dd620dc7b88e5fe05c70e15b" class="btn btn-lg btn-success" data-toggle="modal" data-target="http://miracleart.cn/link/93ac0c50dd620dc7b88e5fe05c70e15bbasicModal">點(diǎn)擊打開(kāi)模態(tài)框</a>
Note that the link element has two custom data properties: data-toggle
and data-target
. data-toggle
Tell Bootstrap what to do, data-target
Tell Bootstrap which element to open. Therefore, whenever such a link is clicked, a modal box with ID "basicModal" appears.
Modal box code:
The following are the marks required to define the modal box itself:
<div class="modal fade" id="basicModal" tabindex="-1" role="dialog" aria-labelledby="basicModal" aria-hidden="true"> <div class="modal-dialog"> <div class="modal-content"> <div class="modal-header"> <h4 class="modal-title" id="myModalLabel">基本模態(tài)框</h4> <button type="button" class="close" data-dismiss="modal" aria-label="Close"> <span aria-hidden="true">×</span> </button> </div> <div class="modal-body"> <h3>模態(tài)框主體</h3> </div> <div class="modal-footer"> <button type="button" class="btn btn-default" data-dismiss="modal">關(guān)閉</button> <button type="button" class="btn btn-primary">保存更改</button> </div> </div> </div> </div>
The parent div of the modal box should be the same as the ID used in the trigger element above. In this case, it is http://miracleart.cn/link/93ac0c50dd620dc7b88e5fe05c70e15bbasicModal
. The aria-labelledby
and aria-hidden
properties are used for accessibility and are recommended to be retained.
Adjust the modal box size:
You can change the size of the modal box by adding a modifier class to the .modal-dialog
div: modal-lg
(large modal box) or modal-sm
(small modal box).
Use jQuery to activate the modal box:
You can use jQuery's .modal()
function to control the modal box:
<a href="http://miracleart.cn/link/93ac0c50dd620dc7b88e5fe05c70e15b" class="btn btn-lg btn-success" data-toggle="modal" data-target="http://miracleart.cn/link/93ac0c50dd620dc7b88e5fe05c70e15bbasicModal">點(diǎn)擊打開(kāi)模態(tài)框</a>

There are three ways to selectively include CSS on a specific page: 1. Inline CSS, suitable for pages that are not frequently accessed or require unique styles; 2. Load external CSS files using JavaScript conditions, suitable for situations where flexibility is required; 3. Containment on the server side, suitable for scenarios using server-side languages. This approach can optimize website performance and maintainability, but requires balance of modularity and performance.

CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.

CSSCounters is a tool for creating automatic numbers. 1. Basic usage: define and operate counters through counter-reset and counter-increment, such as "SectionX." before h2. 2. Advanced usage: Use nested counters to create complex numbers, such as chapter and section numbers. 3. Notes: Ensure the counter is reset correctly, optimize performance, and simplify counter logic. 4. Best practice: clear naming, define counters in CSS, and use counter-increment and counter-reset reasonably.
