Vertical Alignment of Container within a Jumbotron in Bootstrap
Achieving vertical alignment of a container within a jumbotron in Bootstrap can be achieved through various approaches, depending on the level of browser support desired.
The Modern Way
Using Flexbox
For modern browsers that support Flexbox, a more straightforward and consistent approach is to use the Flexbox layout model. By adding the following CSS to your page:
.vertical-center { display: flex; align-items: center; }
you can effortlessly vertically center the container within the jumbotron. Ensure you surround the container with a div with the class ".vertical-center".
The Old-Fashioned Way
For Older Browsers
For browsers that lack Flexbox support, a web-standard technique involving vertical alignment necessitates a bit more effort. Utilize the text-align: center property to align child elements horizontally within the parent. Create a div element initially hidden by display: none with a height equal to or less than the parent. Now, manipulate alignment using vertical-align on the desired element (like the container).
.vertical-center { text-align: center; font: 0/0 a; } .vertical-center .hidden-child { display: none; height: 100%; } .vertical-center.aligned .hidden-child { display: inline-block; vertical-align: middle; }
Within the container, add a display: inline-block; property along with vertical-align: middle; to achieve vertical centering. Note that this involves some extra markup to mimic the effect of Flexbox.
Browser Considerations
Remember that Internet Explorer 8 and 9 won't correctly interpret the inline-block technique, requiring alternative solutions.

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.

Autoprefixer is a tool that automatically adds vendor prefixes to CSS attributes based on the target browser scope. 1. It solves the problem of manually maintaining prefixes with errors; 2. Work through the PostCSS plug-in form, parse CSS, analyze attributes that need to be prefixed, and generate code according to configuration; 3. The usage steps include installing plug-ins, setting browserslist, and enabling them in the build process; 4. Notes include not manually adding prefixes, keeping configuration updates, prefixes not all attributes, and it is recommended to use them with the preprocessor.

In CSS, selector and attribute names are case-sensitive, while values, named colors, URLs, and custom attributes are case-sensitive. 1. The selector and attribute names are case-insensitive, such as background-color and background-Color are the same. 2. The hexadecimal color in the value is case-sensitive, but the named color is case-sensitive, such as red and Red is invalid. 3. URLs are case sensitive and may cause file loading problems. 4. Custom properties (variables) are case sensitive, and you need to pay attention to the consistency of case when using them.
