jQuery (Ajax) Contact form with all elements

This is my default CONTACT form built with jQuery and CSS.
The form uses a jQuery call to a PHP script that inserts data into a Mysql DB and sends two emails of confirmation, all this under the hood… meanwhile, there is a CSS only animation that displays a message that the data is been sent to the server and shows a positive message if that data was sent without errors and an error message if there was an error.

jQuery + CSS – Activate DIV background colour and deactivate other DIV’s bg colour

This little code delivers all the magic, if you are into one page websites/apps like me, this short code will simply save you lots of time.
This code simply activates(changes the style) of an DIV that is clicked on and removes the same style applied to other DIV(active button) in case it has another active style applied to another DIV.
It can be combined with a little CSS code to display a beautiful color transition.
You can see the code running on this little jsFiddle I made: https://jsfiddle.net/cosminr/ampjtwjp/

PHP & HTML – easy spam prevention using hidden form fields (sample code)

The easy and fast working method of securing your forms agains spam bots is as easy as a few lines of PHP and HTML code.

Spam bots, at least, most of them, crawl random websites and fill their forms with all kind of ads or unwanted content. There are a lot of alternatives to stop this, Google Captcha, reCaptcha, etc., I used all of this methods, they work pretty well but, sometimes, when you move your site to a new server or domain, you need to spend a lot of time working around this methods to make them work again.

I simply tried a really simple method that I found a few years ago, the method implies using simple PHP and HTML to trick the bot to fill a field that the user doesn’t see(hidden via CSS).

The code is pretty simple…

Here is the HTML…

How to Optimize Your Website And Obtain a Google Page Speed of 98-100?

First, please backup your files before you start modifying anything I write in this post.

Thank You!

First, why you should follow my advice? Well, almost anyone can tell you that a fast website is a good website and a good website is a mobile and desktop 100% compatible website but, as a developer, you need to test your site with Google’s Page Speed tool(https://developers.goo…).

Obtaining a good grade there can help your search engine traffic… So, what Google Page Speed score your project gets?

I’ve done a few projects with 98-99 out of 100, and a few with perfect 100.

I will list here a few “secrets” I used to boost my grade from 68/100 to 99/100.

1. Use only inline CSS

You need to use only inline css, period. Don’t link to any external frameworks(Bootstrap, etc.), don’t link to any Google Fonts file, to any particular style…

If you want to be productive, you ca use PHP to include_once(“”); your css files into the interpreted file.

If you want to use fontawesome or Google Fonts, you can put fontawesome file before you close your </body> tag.

You can also modify the Google Fonts .css file and include it inline into your source via PHP. Also, you can remove all the Vietnamese or Greek fonts from the Google Fonts file and use only the Latin style, works with english projects and most of the languages.

2. Insert the .js files at the end of the file

This is no secret that, inserting the .js files before you close </body> tag can get you a good Page Speed grade.

3. Use Server Side compression(gzip)

This is a pretty easy step, I provided instructions here on another post on how to do that.

4. Optimize images

Don’t exaggerate with images, use a low resolution image thumbnail, I use only < 10kb images. Specify the width and height of the image. You can use a free online tool to reduce the size of the images.

5. Minify css, js and html

This step gives anyone a lot of work if you are updating your site constantly… You can use free online tools to minify your css, html and js code.

6. Reduce the Server Response Time

Don’t load your server with requests, use, as much as you can only static content or make Ajax requests to content.

Bonus Point!

Transform your favicon in BASE64 text and include the code via PHP and get rid of a few connections that can slow down your website… I use this tool to convert my favicons: https://xaviesteve.co…

 

Hope this experience helps, try and play with this list and tell me your result.

Take a look at a sample page that I’ve recently made and got a great score: https://developers.google.com…

Best responsive CSS framework so far

There are a lot of CSS frameworks that use a grid system to display content on mobile and desktop(eg.: Bootstrap, Foundation…) but why load a lot of styles that you don’t need on your project? For example a series of form styles when you only need a simple Material Design form?

Lately I discovered Simple Grid, a simple, minimalistic responsive css framework that delivers only the basic functions of the grid.

You can take a look here: http://simplegrid.io/

Delayed color transition on .class:hover (button/link)

Sometimes you just want to add a beautiful delayed transition to your form button or menu links, this one works only on the desktop version/no mobile experience is seen…

CSS

.send-btn {
background: rgba(88, 214, 141, .8);
transition: all 0.6s cubic-bezier(.25,.8,.25,1);
}
.send-btn:hover { background: rgba(88, 214, 141, 1) }

CSS/form input with width: 100% goes outside parent’s bound

There is a pretty simple solution for this problem:

CSS

.example_class {
          box-sizing: border-box; /* works with Ch, Saf 5.1+, IE 8+, Op 9+  */
}

(Method of specifying whether or not an element’s borders and padding should be included in size units)

Responsive background image in card-header (Bootstrap 4)

This is a Bootstrap 4 version of the Responsive Background Image in Panel Heading (Bootstrap). Since they changed the panel class with the card class in Bootstrap 4, you just need to change the old Bootstrap 3 class names… here is my code and demo.
