New Features in HTML 5.1

| Comments

HTML started evolving at a faster pace after the major release of HTML 5.0, W3C and WHATWG is developing the standard backed by a great community to bring in useful features in every version. Let’s look at some of the key features of HTML5.1

Context Menus / Right Click Menus

We have been using right click on web browser to use certain actions on page like copy, paste, define, etc., Well you can use the <menu> tag to define a menu consisting of one or several <menuitem> elements and then bind it to any element using the contextmenu attribute.

The <menuitem> can be defined as three types:

  • checkbox to select or deselect an option
  • command to execute an action on click
  • radio to select one option from a group

PS. At the time of writting this post, the feature is only supported in firefox.

Details and Summary Elements / Accordions

We have long been using accordions in our websites if we want to show less content and on user interest reveal the extra information. But the way we usually do is with help of JS/CSS. Well with HTML 5.1 there is this new <details> & <summary> tag to take care of those.

The way to do it is simple define a parent <details> element with a <summary> element inside it. Clicking on the summary toggles the visibility of the rest of the content from the <details> element.

New Input Types (month, week, datetime-local)

The input type is getting enhanced more and in HTML 5.1 we have three new types.

  • month, week - allow you to select a week or a month. You get to see a dropdown calendar like the one we have seen in jQueryUI Calendar. When you try to access the values from JavaScript you will receive a string something like: "2016-W43" for the week input and "2016-10" for the month input.
  • The datetime-local input consists of two parts — the date, which can be selected in a similar way to the week or month input, and the time part, which can be typed in separately.

Validating Forms with form.reportValidity()

HTML5 defines the form.checkValidity() method which allows you to check the inputs of a form against the defined validators and returns a boolean value as a result.

The new reportValidity() is very similar — it also allows you to validate a form and retrieve the result, but additionally reports the errors to the user right in the browser.

Multiple image support for responsive design

In HTML 5.1, you can use <picture> tag together with the srcset attribute to make responsive image selection possible. The <picture> tag represents an image container that allows developers to declare different image resources in order to adapt to the user viewport size, screen pixel density, screen type, and other parameters used in responsive design.

The <picture> tag itself doesn’t display anything, it functions as a context for the multiple image resources. You need to declare the default image resource as the value of the src attribute of the <img> tag, and the alternative image resources go within the srcset attributes of the <img> and <source> elements.

Code example:

  <source srcset="mobile.jpg, mobile-hd.jpg 2x" media="(max-width: 360px)">
  <source srcset="large.jpg, large-hd.jpg 2x" media="(min-width: 1920px)">

  <img src="default.jpg" srcset="default-hd.jpg 2x" alt="your image">

My Ultimate Self Guide - for Better Living

| Comments

Everyone has their own way of living

This here is my self-guide I use to improve myself in a consistent manner. I learned this from many different sources(articles, books, word of mouth, etc.,) so If I haven’t mentioned your name/source let me know in comments I will give credits for the same.


“Each good morning we are born again, what we do today is what matters most” — Buddha

  • Become an early riser. It’s hard at the start, but if you do anything for 30 days a new habit is created.
  • If you have the gift of waking up automatically you are gifted, Others(majority) don’t keep your alarm in reachable area/in bed
    • Avoid Snooze/Negotiating with your pillow, As soon as the alarm goes, wake up and change the environment to get yourself up easily.
    • Do some activities immediately (Wash your face, Brush, Etc.,)
  • Do exercise in the morning to feel happy, be more productive & create a healthy lifestyle.
    • At least a few mins is good enough to boost Endorphins (1 min is enough for new starters - check Kaizen Technique)
  • There are hundred’s of articles explaining the benefits of doing exercise in the morning. So I leave it there

Waking up early and developing a routine can transform you into a very intelligent, organized, and successful person within a relatively short period of time (approx. 1–10 years). Just imagine this in your mind (2Hrs every day for 10 years)

“Lose an hour in the morning, and you will be all day hunting for it” — Richard Whately

First Things First

“Good is the enemy of great.” — Jim Collins

It’s easy to start the day with something that seems to be good/easy but ultimately isn’t all that important. Watch below video where Stephen Covey explains the importance of putting “first things, first.”

  • Read uplifting content to motivate, inspire you for the day (max 10 mins)
  • Do #1 priority task in the morning. Never let easy/small task fill in your day
  • Learn how to Prioritize your tasks

Notes on Self Development

Self-improvement isn’t a destination. You’re never done

  • Create Goals (Daily, Weekly, Monthly, Yearly)
    • Avoid Unrealistic goals: Do not overcommit and get disappointed if you don’t achieve.
    • Create reasonable and achievable goals to get your Endorphins level up. One step at a time!
  • Maintain goal(Daily, Weekly, Monthly, Yearly) streaks to make yourself consistent
    • Use App like Today to set time-based reminders and track streaks
  • Give 10x the value of what you say you will
    • It’s not about the price, it’s the value that matters.
    • “Quality is not an act, it is a habit.” — Aristotle
  • Use Kaizen Technique to create habits
    • “Little strokes fell great oaks.” —  Benjamin Franklin
    • Do something useful every day just for 1 min(very less time and easy do-able) and over the time it will become as your habit
  • Wherever You Are, Make Sure You’re There, Most people are never present
    • Google Search: In flow, Deep work, Focus.
  • The world looks for the best always; not the average person
    • Read Book: The Dip A Little Book That Teaches You When to Quit (and When to Stick)
    • If you don’t quit on bad/time-consuming tasks you are not going to succeed on that righteous goal in your todo list
    • So quit on unwanted things and spend time on useful things and be the best
  • Be consistent
    • The difference between Amateur and Professional is; the later is consistent no matter what.
    • If you’re not that good now, consistency will make you better.
  • Embrace multiple learning techniques and never quit learning
    • “Anyone who stops learning is old, whether at twenty or eighty.” — Henry Ford
    • By consistent learning - You make new connections in your brain, Open yourself to a new world of experience

Keep Your Energy Up

  • Two keen things to be limitless - Body, Mind
    • Body: Cardio(run), Strength(gym), Flexibility(yoga, sports)
    • Mind: Meditation, Brain Exercise
  • Eat healthily, Drink 3-4 liters of water every day
  • Stop looking for quick methods to make your body fit as it’s not going to last, instead gradually adopt to healthy life (Approx 1-4 Years)

Things to do before you go to sleep

The success of your morning begins the night before.

  • Having 7Hrs of good sleep is very important to wake up fresh and recharge your brain. Not having enough sleep ruins next day, so avoid it at any cost.
  • Take a few mins every night to mentally prepare yourself for next day. Make sure you write down your #1 priority task for tomorrow
  • Turn off WIFI/Mobile data
  • Keep your mobile/alarm far away from bed (To wake yourself up in one alarm)
  • Read a physical book, Avoid e-devices(kindle/tablet/mobiles)
  • Think about the tasks & goals you need to accomplish tomorrow and go to sleep
    • “Never go to sleep without a request to your subconscious.” — Thomas Edison
    • Your subconscious mind works when you sleep (Book: The Power of Your Subconscious Mind, Google search to find out more)

When you wake up the next morning, you’ll be primed for success. The only thing you need to do is immediately get out of bed.

“Successful mornings don’t happen by chance. They happen by choice. Neither does a successful life.” — Benjamin P. Hardy
