Bootstrap 4 Alpha 6 Major Components in Flexbox

Bootstrap-4-Alpha-6

Alpha 6 has just launched and it becomes the biggest ships to date.  Hence, in this article we will describe its grid system and major components in flexbox. If you are web developers who are currently working on WordPress, this article is for you. Discover what’s new with Bootstrap 4 Alpha 6, here!

Embracing Flexbox
As bootstrap is now flexbox by default, you can control your grid system and core components and provide unparalleled flexibility. However, it may be dropping IE9 support yet brings significant improvements to component layout, alignment, and sizing.

If you have no idea about Flexbox, here are some benefits that you can have when applying Bootstrap 4:

  • No more HTML white space or broken table-style rendering
  • Auto margins for easy spacing
  • Automatic equal-width grid columns (e.g., two columns are automatically 50% wide)
  • Equal height and equal; width cards
  • Utility classes for easily changing display, direction, alignment, and more.
  • Justified navigation and button groups
  • Vertical and horizontal centering without hardcoding values with translate or margin

In fact, almost every component now takes advantage of flexbox. This is because less reliance on clearfix, more control over Dom, and visual order, and fewer bugs. Even, Carousels, a more complex component has used Flexbox in some areas.

Responsive Utilities and the Great Infix
Among so many advantages that Alpha 6 offered, they also made two important changes to their naming scheme.

  • First, we’ve dropped the –xs infix from our lowest (extra small) breakpoint. However, xs isn’t a responsive breakpoint just like sm, md, lg, and xl. This is because it doesn’t start applying styles at a min-width and up. It can be applied to everything as there’s no bounding @media query.
  • Second, to better articulate their property value pairings, we’ve renamed several classes. Instead of pull, we use float. You can start with the property name, instead of creating new names for the various flexbox properties.

Combine them together and you’ll get updated class, such as .col-6, .d-none, .float-right, .d-md-flex, .justify-content-end, and .text-lg-left. With these classes, you can have immense power and customization to folks building with Boothstrap.

More Grid Improvements
You will also have more grid improvements. By adding responsive auto sizing columns, more container padding options, and add any number of .col-* classes, the result will automatically be equal in width.

To remove gutters from grid rows and their columns, you can use the .no-gutters modifier.

Updated Navbar
If you find that the Alpha 5 navbar still needs more improvement, you’ll see that the Alpha 6 is done perfectly. The navbar has been rewritten and it provides better built-in responsive behaviors and improved layout customization.

Here are some of the lists of the updates:

  • The responsive navbar toggle, .navbar-toggler, has also been updated. The icon is once again a child element, .navbar-toggler-icon, for improved customization. It also includes easy modifiers for absolutely aligning it to the top right or top left.
  • Navbar navs no longer require the .nav base class. While it provided a starting point, these shared styles often got in the way of navbar behaviors. Now it’s just .navbar-nav and utilities for alignment.
  • Navbars are built with flexbox! Instead of floats, you’ll need flexbox and margin utilities.
  • The .navbar-toggleable classes are now applied to the .navbar instead of the .collapse within. This allows us to provide better responsive behavior with just one class change.

MySQL 5.7 Reference Manual

My SQL

Nowadays, MySQL is the most popular database system used with PHP among so many developers. PHP combined with MySQL are cross-platform which you can develop in Windows and serve on a Unix platform. Basically, tables stores the data in a MySQL database. A table consists columns and rows which is a collection of related data. Databases are useful for storing information categorically. My SQL is an open source relational database management system (RDBMS).  So, whether you are a mobile or web developer, it is never too late to learn more about MySQL 5.7. Here are the details and don’t hesitate to check them out!

MySQL has supported for full-text indexing and searching, such as follows:

  • A full-text index in MySQL is an index of type FULLTEXT.
  • Only with InnoDB or MyISAM tables, you can create Full-text indexes, and can be created only for CHAR, VARCHAR, or TEXT
  • As of MySQL 5.7.6, My SQL provides a built-in full-text ngram parser. It supports Chinese, Japanese, and Korean (CJK), and an installable MeCab full-text parser plugin for Japanese. Parsing differences are outlined in Section 13.9.8, “ngram Full-Text parser”. Then, Section 13.9.9, “MeCab Full-Text Parser Plugin”.
  • CREATE TABLE provides A FULLTEXT index definition or adds later using ALTER TABLE orCREATE INDEX.
  • To load large data sets faster, you can use a table that has no FULLTEXT index. Then, create the index to load data into a table that has an existing FULLTEXT index.

By using  MATCH() … AGAINST syntax, you can perform full-text searching. MATCH() takes a comma-separated list that names the columns to be searched. You can use AGAINST to take a string and an optional modifier that indicates what type of search to perform. Create search string that is constant during query evaluation through string value. This rules out, for example, a table column because that can differ for each now.

There are three types of full-text searches:

  • A natural language search interprets search string as a phrase in natural human language. There are no special operators. The stop word list applies if the modifier gives or not give the IN NATURAL LANGUAGE MODE. Full-text searches are natural language searches.
  • Using the rules of a special query language, a Boolean search interprets the search string. The string contains the words to search for. It can also contain operators that specify requirements such that a word must be present or absent in matching rows. It also should be weighted higher or lower than usual. In Boolean search interprets, search index will omit certain common words. Besides, some words do not match if present in the search string. The IN BOOLEAN MODE modifier specifies a Boolean search.
  • A modification of a natural language search is a query expansion. To perform a natural language search, you can use search string. After adding the words to the search string, then words from the most relevant rows returned by the search. The search is done again. From the second search, the query returns the rows.

Find Out the Right Types of SSL Certificate for Your Website

Find out the right types of SLL certificate fo your website

Since, Google cybercrime gets bigger and bigger nowadays, the way Google assesses a website is change. In fact, Google is among the most proactive, they give better rewards to sites whose adding SSL certificates (or HTTPS). This makes many SEO engineers put a good attention on SSL certificate for their better SEO service. But, you need to be more careful in choosing the right SSL certificate, as there are many types of SSL certificate. Each SSL types use the same standard encryption methods but each option has their own requirements and distinct characteristics.

Option #1. Single Domain

Single domain (or single-name) SSL certificates protect a single domain. This SSL type really works well for simple and straightforward content-based sites. These sites include B2B sites, e-commerce ones where all transactions occur on a single domain. Someone has to get an authenticated domain ownership when she/he wants to get a “Domain-validated”.

Option #2. Multi-Domain (SAN)

Multi-domain SSL certificates are also what they sound like. Multi-domain SSL certificates are also referred to as “SAN” (for Subject Alternative Names). With SAN and one multi-domain SSL certificate, it will cover a suite of sites. So, they provide flexibility for covering sites that might go away or not yet exist.

Option #3 Wildcard

If you want to cover all subdomains on a single root domain or host name, wildcard SSL certificates will be suitable for you. It uses an unsecure, content-driven ‘marketing’ site on the primary domain. Fortunately, this SSL’s type can run all purchase-related through a secure subdomain. With this single wildcard SSL certificate, you can simplify the mess, and it also protects the main site.

Option #4 Organization

Organization SSL certificates works to authenticate a company’s identity and information, such as the company’s primary address, and etc. You may think that this is similar to single domain. But in organization SSL certificates, you will get more content-based sites. By this, you don’t need to secure an e-commerce or payments component.

Moreover, you also will be asked to confirm and authenticate the other organization-related details as well.

Option #5 Extended

The last option, called as extended is better known as the most secure option. They do the extra organization validation bit by verifying the domain. It also double checks the legal corporation. It will also show a green address bar on most modern browsers for your troubles. In Chrome, you’ll also get the company name like this Twitter example below:

Credibility is what you’re paying for here. But, the secure connection uses on your site are that different than any other reputable SSL connection.

Hence, by selecting the right SSL certificate types, you’ll get a single certificate to purchase and set up to protect multiple different sites.
